> in feature preview for all paid Claude users in the United States. Support for users on our free plan and more countries is coming soon

US only

More countries soon.
Excited to see this. I've really been enjoying Claude. It feels like a different, more creative flavor of experience than GPT. I use Claude a lot for dialogues and exploring ideas, like a conversational partner. Having web access will add an interesting dimension to this.
Ditto. I use Claude 3.7 to refine drafts of research papers and ask it “What have I missed?”.

Now I can prompt Claude to ping PubMed and make sure that its suggested references are verified. Each citation/claim should be accompanied by a PMID or a DOI.

I hope this works!

That's a great way to use it!
That's how I use it as well! It'll also occasionally hallucinate things, but much less often than other AI tools I've tried. But typically I'll just run things by it that I'm question myself about, or if I want to solidify a concept I'll ask it if my understanding is correct.

It's also fun to ask the same question to multiple AI tools and see how the answers differ. Usually Claude is the most accurate and helpful, though.

Excited to see how this compares to Perplexity or Gemini. I remember that ChatGPT used to be able to search the web, but last I checked it it couldn't. I wonder why they removed that feature
Search was not removed from ChatGPT, although it can be glitchy at times.
Also not all models support it. I think only gpt-4o and gpt-4o-mini support it, although I haven't triple checked that.
ChatGPT can search the web (I just checked in my account). It appears to be available for all users (not just paid): https://help.openai.com/en/articles/9237897-chatgpt-search
I definitely tried to web search with ChatGPT a few weeks ago and it couldn't. I don't think I'm making this up. Unless I suffered a TBI.
It told me it can't search the web and then proceeded to search the web
About half my requests end up going to web search. But if you ask it for something specific like "find an X-ray image with an abnormality," then it refuses.
Web search is available for some but not all of their models. It is not particularly obvious from their UI which models have this feature.
As sibling said, search was nog removed. But not all models can use the web search, maybe that is causing your perception?
Couldn't a lot of front-ends using Claude API do this already? What's new?
If that's true, they are using a separate search API to get search results and feed it into a regular Claude API call. The difference here is that Anthropic is integrating it directly, like OpenAI and Google have. It doesn't look like it's in the API yet, but presumably that's coming. Then, as with gpt-4o and the Gemini models, you can make a single API call and it will do the searching for you and incorporate the results.
I wonder if it will actually respect the robots.txt this time.
almost no one does, robots.txt is practically a joke at this point — right up there with autocomplete=off
In what circles is it a joke? Google bots seem to respect it on my sites according to logs.
Apparently, the regular search crawler does it, but the ai thingie doesn't.
Huh? You can add Google-Extended[1] to opt out from Generative AI summaries.

[1] https://blog.google/technology/ai/an-update-on-web-publisher...

Google will still scrape it for training data either way, this only impacts search results.
> Today we’re announcing Google-Extended, a new control that web publishers can use to manage whether their sites help *improve Bard and Vertex AI generative APIs*, including future generations of models that power those products.
Can confirm. My website is flooded with AI bots despite attempts to block crawlers to certain parts of it.
I know an artist that had noindex turned on by mistake in robots.txt for the last 5 years - google, kagi and duckduckgo find tons of links relevant to the artist and the artwork but not a single one from the website.

so not seem to or apparently but matter of fact like. robots.txt works for the intended audience

AI crawlers are part of the intended audience.
Not being indexed is different from not being crawled.
It's in a small circle of those that do. Blame the internet archive for starting this trend: https://blog.archive.org/2017/04/17/robots-txt-meant-for-sea...
Given websites do disappear or worse, get their content adultered. Also given the long history of the internet archive as a non profit - and the commons service it has served so far, the joke would be to see that bot honor it.
lol IA did not start that, if anything they were late to the game. only the top handful of US-based search engines ever bothered respecting it in the first place
Sorry to intrude with something unrelated. But YC closed the earlier discussion. Saw your comment about Kannel WAP of few months back and wanted to ask if do you know of any WAP Push full service provider still in operation.
Nah I just know about that public gateway I linked. I can't use it anymore as 2G was shut down on my local towers back in January.
A small number of search engines respect it, no one else does. Just about every content scraping bot ignores it, including a number of Google's.
I have replaced all robots.txt rules with simple WAF rules, which are cheaper to maintain than dealing with offending bots.
For my personal stuff I also included a Nepenthes tarpit. Works great and slows the bots down while feeding them garbage. Not my fault when they consume stuff robots.txt says they shouldn't.

I'm just not sure if legal would love me doing that on our corporate servers...

The WAF rule matches based on the user agent header? Perplexity is known to use generic browser user agents to bypass that.
I do essentially both: robots.txt backed by actual server-level enforcement of the rules in robots.txt. You'd think there would be zero hits on the server-level blocking since crawlers are supposed to read and respect robots.txt, but unsurprisingly they don't always. I don't know why this isn't a standard feature in web hosting.
robots.txt is meant for automated crawlers, not human-driven actions.
Every automated crawler follows human-driven actions.
Conversely, every browser is a program that automatically executes HTTP requests.
Yet they respect a lot of things meant for machine to machine interaction. Like server return codes, cookie negotiations, and CAPTCHAs if they behave a certain way.

So they sometimes hit bollards and turnstiles made for other types of code which executes HTTP requests. So they're bots basically, but better (or suitably) behaving ones.

Browsers let you visit websites without regard for robots.txt.
It must form the search index somehow. That is prior the human action. Simply it would not find the page at all if it respects.
I remember in late 90s/early 2000 as a teen going to robots.txt to specifically see what they were trying to hide and exploring those urls.

What is the difference if I use a browser or a LLM tool (or curl, or wget, etc) to make those requests?

careful, some of those are honey pots or trip wires
But how did you find those sites that had the robot.txt to begin with? LLM must somehow find the existence of those pages and store that information before they can crawl them further or mark as acceptable source.
I am a human so I can visit other sites with links or from word of mouth or business cards or literally anywhere?

LLM finds out about it from me, when I ask it to go to the link.

You don’t accuse browsers of “somehow find[ing] the existence of those pages”. How does a browser know what page to visit?

The user tells it to.

If I prompt an LLM “go to example.net and summarize the page” how is that any different from me typing example.net in a browser URL bar?

That is certainly true. But that is not how these work 99% of the time. This post was originated by "search".
I think a distinction needs to be made between ingesting for LLM training and ingesting / crawling because a human asked it to during an inference session.

I have been talking about the latter, agree the former is abusive.

Let's say you had a local model with the ability to do tool calls. You give that llm the ability to use a browser. The llm opens that browser, goes to Google or Bing, and does whatever searches it needs to do.

Why would that be an issue?

In practice, robots.txt is to control which pages appear in Google results, which is respected as a matter of courtesy, not legality. It doesn't prevent proxies etc. from accessing your sites.
if a human triggers the web crawlers by pressing a button, should they ignore robots.txt?
If a human triggers a browser by pressing a button, should it ignore robots.txt?
Are you arguing that these are equivalent actions?

The entire web was built on the understanding that humans generally operate browsers, and robots.txt is specifically for scenarios in which they do not.

To pretend that the automated reading of websites by AI agents is not something different…is quite a stretch.

I see it as very different. I the human want the data from that request. I am using a tool to get it for me.

Should I not be able to execute curl to download a webpage because the "understanding that humans generally operate browsers"?

> I the human want the data from that request. I am using a tool to get it for me.

Isn't this a bit of an oversimplification, though? Especially when the tool you're using completely alters the relationship between the content author and the reader?

I hear this argument often: "it's just another tool and we've always used tools". But would you acknowledge that some tools change the dynamics entirely?

> Should I not be able to execute curl to download a webpage because the "understanding that humans generally operate browsers"?

Executing curl to download a webpage is nothing new, and compared to a traditional browser, has about the same impact. This is still drastically different than asking an AI agent to gather information and one of the pages it happens to "read" is the one you were previously navigating to with a browser or downloading with curl.

If you're a content creator who built a site/business based on a pre-LLM understanding of the dynamics of the ecosystem, doesn't it seem reasonable to see these types of "readers" differently?

It's reasonable for the content creator to see it differently, but I don't think it's reasonable to expect everyone around the content creator to contort any new approach to the needs of the pre-existing business model.
No, whether I curl it, or I use a browser, or an LLM, it is essentially ALL the same, unless of course the LLM crawls it by itself, without human interaction.

If the scale bothers you, block it, just like how you would block any other crawlers.

Other than that, we all wanted "ease-of-access" (not me though), and now we have it. It does not change anything.

What if the crawlers are faking their identity (As they are doing it right now)
Well, how do we deal with it in terms of DDoS?
I agree. This came up in terms of copyright either, or who is pressing the shutter and who owns the copyright to the photo taken. I personally think that the copyright belongs to me, because I, a human, made the detailed prompt, the tool just generated it. Do I not own the copyright if I make something using Photoshop? As far as I know, I do. So, how is AI any different that needs human action (i.e. be prompted)? Because it is better than Photoshop? That is not a good argument, IMO.
So, do you mean LLMs are human-like and conscious?

I thought they were just machine code running on part GPU and part CPU.

(comment deleted)
There’s a human using the LLM. In a live web browsing session like this, the LLM stands in for the browser.
Would you believe that humans turn on traditional web-crawlers as well?
I think they mean that it's a tool accessing URLs in response to a user request to present to the user live - with that user being a human. Like if you used some webpage translation service, or non-ML summarizer.

There's some gray area though, and the search engine indexing in advance (not sure if they've partnered with Bing/Google/...) should still follow robots.txt.

Yeah, that seems to be a big distinction. If I tell my AI to summarize the headlines from my three favorite news sites every morning, it's just carrying out my request same as if I'd clicked to them, so that seems fine.

But if I say, "Search the web for a low-carb chicken casserole recipe that takes squash and cottage cheese," then it's either going to A) send queries to a search engine like Google, in which case robots.txt already should have been respected, or B) check its own repository of information it's spidered before I asked the question, in which case it should have respected robots.txt itself.

I don't think it should. If a user asks the AI to read the web for them, it should read the web for them. This isn't a vacuum charged with crawling the web, it's an adhoc GET request.
You could make this justification for a lot of unapproved bot activity.
How can you be so sure? Processors love locality, so they fetch the data around the requested address. Intel even used to give names to that.

So, similarly, LLM companies can see this as a signal to crawl to whole site to add to their training sets and learn from it, if the same URL is hit for a couple of times in a relatively short time period.

No thank you, when I define a robots.txt file I expect all automated systems to respect it.
But this isn't automated. This is user-driven.
If this feature isn’t already part of the Claude API it likely will be at some point, in which case many Claude requests will be automated with no way to distinguish between user-driven or otherwise.
Simply put, at the end of the day you lose, AI blocking will not work.

I mean, currently the AI request comes from the datacenter running the AI, but eventually one of two things will happen.

AI models will get small/fast enough to run on user hardware and use the users resources: End result? You lose. The user will set their own headers and sites will play the impossible game of identifying AI.

AI sites will figure out how to route the requests via any number of potential methods so the requests appear to come from the user anyway: End result? You lose. The sites attempting to block will play the cat and mouse game of figuring out what is AI or not AI.

Note, this doesn't mean AI blocking isn't worth doing, if nothing else to reduce load on the servers. It's just not a long term winning strategy.

Depends if the legal system survives.

You may not be able to stop AIs from crawling web sites through technological means. But you can confiscate all the resources of the company that owns the AI.

Ideally bad behavior by AI companies should trigger crushing fines and jail time for executives.
It’s clearly not. The human user is not requesting the resource. The AI is.
It's clearly not. The human user is not requesting the resouce. The web browser is.

Where do we stop here? at "please drink a verification can and maintain eye contact at all times"?

Someone should call the robots.txt police then, there's a bandit on the loose!
A browser is automated too.
Browser don't automatically browse, unless they are being automated.
Any AI tool I make will ignore robots.txt on principle. Artificial humans should have equal rights as real humans.
> Artificial humans should have equal rights as real humans.

This is ridiculous and plain evil.

People like you are ruining the internet.
Think of the "searching" LLM as a peon of the user, the user asks, the peon performs. In that essence, searching by the LLM should be human-driven and must not be blocked. It's just an automated system doing the search not your personal peon.
Can't you make the same argument for a crawler? The user wants information, the peon (crawler) just compiles it for them.
Then you’ve fundamentally misunderstood what a robots.txt file does or is even intended to do and should reevaluate if you should be in charge of how access is or is not prevented to such systems.

Absolutely nothing has to obey robots.txt. It’s a politeness guideline for crawlers, not a rule, and anyone expecting bots to universally respect it is misunderstanding its purpose.

> Absolutely nothing has to obey robots.txt

And absolutely no one needs to reply to every random request from an unknown source.

robots.txt is the POLITE way of telling a crawler, or other automated system, to get lost. And as is so often the case, there is a much less polite way to do that, which is to block them.

So, the way I see it, crawlers and other automated systems have 2 options: They can honor the polite way of doing things, or they can get their packets dropped by the firewall.

>You can now use Claude to search the internet to provide more up-to-date and relevant responses.

It's a search engine. You 'ask it to read the web' just like you asked Google to, except Google used to actually give the website traffic.

I appreciate the concept of an AI User-agent, but without a business model that pays for the content creation, this is just going to lead to the death of anonymously accessible content.

Well I expect eventually the agent will be able to act on your behalf with your credentials.
And as advertisers get declining human views on their ads, the value of the business model will dwindle until it needs to be replaced by other forms of revenue. Content that can't shift business models and requires revenue to continue will die off.

Edit: Maybe that's fine, maybe that's bad. Maybe new models will emerge and things will reshape. But I'm just supporting the case that AI agents will pressure the current "free" content economy.

the free content economy is bogus, I am part of a growing segment of users that just block ads anyways.
I'm also and I pay for the services that I use to not see ads, but I don't pay for every single one. For example a local classified website is financed by ads, and I don't think anybody will pay for just looking at stuff there. Maybe they can switch to the model where the person puting the thing for sale would pay but hat is something where we are not currently.
If that's the case, then you might as well just list it on eBay and skip the local classifieds/craigslist/facebook/whatever.

Is that a world we actually want?

Which is fine if you’re paying for a subscription. Will probably soon see one subscription rate allowing AI access on your behalf, and a lower rate without that access. Since a human accessing without a bot is likely to see the ads.
What was the web like before wide spread internet ads, auth, and search engines?

Did all those old sites have “business models”? What did the web feel like back then?

(This is rhetorical - I had niche hobby sites back then, in the same way some people put out free zines, and wouldn’t give a damn about today’s AI agents so long as they were respectful.

The web was better back then, and I believe AI slop and agents brings us closer to full circle)

It was much smaller and people wrote on Usenet to connect with one another, not to shout in the void while corporations hoover all the content.
I recall a hotelier who advertised free WiFi at a time when everyone thought that monetizing WiFi was a hot new revenue stream.

"What," he was asked, "is the business model for free WiFi?"

"What," he retorted, "is the business model for free washrooms?"

The web was so much smaller back then. Just imagine I turned the user (not automated in any way) based clicks that can occur from a link like reddit today towards your site then. We called it the slashdot effect way back, but that many clicks might take down the entire ISP.

Many of these sites business model was simply "don't cost too much". The moment the web got big a lot of these sites died. Now add DDOS for fun and profit became a thing, most people moved to huge advertising based providers/hosters (think FB).

Simply put, we're never getting the old web back. Now, we may get something new, but it will be different and still far more commercial.

(comment deleted)
IDK bittorrent is pretty effective at hosting bytes. I think if something like IPFS takes off in our generation there will be no need for advertising as an excuse for covering hosting costs in the client-server model.

As for funding "content creation" itself, you have patronage.

You can't expect the benefits of public web without bearing the costs. Just put your stuff under a auth wall (can even be free) and no one will crawl it.
> This isn't a vacuum charged with crawling the web, it's an adhoc GET request.

Doesn't matter. The robots-exclusion-standard is not just about webcrawlers. A `robots.txt` can list arbitrary UserAgents.

Of course, an AI with automated websearch could ignore that, as can webcrawlers.

If they chose do that, then at some point, some server admins might, (again, same as with non-compliant webcrawlers), use more drastic measures to reduce the load, by simply blocking these accesses.

For that reason alone, it will pay off to comply with established standards in the long run.

In the limit of the arms race it's sufficient for the robot to use the user's local environment to do the browsing. At that point you can't distinguish the human from the robot.
That's not how many of these services work though. The websearch and subsequent analysis of the results by an LLM are done from the servers of whoever supplies the solution.
Many if not most websites are paid for by eyeballs not by get requests. A bot is a bot is a bot. Respect robots.txt or expect to have your IPs banned.
It may not be very long before the big majority of web searches are via AI. If that happens, blocking AI will mean blocking most people too.

You’d already be blocking me as I’d guess I now search via AI >90% of the time between perplexity, chatgpt, deep research, and google search AI.

>It may not be very long before the big majority of web searches are via AI. If that happens, blocking AI will mean blocking most people too.

If that happens a big majority of websites will go bankrupt and won't exist anymore to be searched. Problem solved!

big doubt on that and maybe that's a good thing? Let's be honest, right now most of the web is dominated by low effort spam. Taking money away from view farming would dramatically increase the web quality of the web. Suddently that guy who's really into "key gardening" doing research and publishing detailed results on his website actually has viewers — isn't this good? Especially since website hosting is close to being free these days.
> big doubt on that and maybe that's a good thing? Let's be honest, right now most of the web is dominated by low effort spam.

I think that is funny considering it is likely going to have the exact opposite effect.

Low effort blog spam is cheap to make. And it is often part of content marketing strategies where brand visibility is all that matters, so not much harm if the viability is directly on your site or in an AI chatbit interface.

Quality content on the other hand is hard to make. And there are two groups of people who make such content:

1. individuals or small groups that like to share for the sake of sharing. They likely won’t care about the AI crawlers stealing their content, although I think there is a big overlap between people who still run blogs and those who dislike AI.

2. small organizations that are dedicated to one specific topic and are often largely ad financed. These organizations would likely stop to exist in such an AI search dominated world.

> Especially since website hosting is close to being free these days.

It is under specific circumstances. The problem is that those AI crawlers don’t check by once in a while like Google does but instead they hit the site very frequently. For a static site this won’t be much of an issue except for maybe bandwidth. For more complex sites like - say - the GitLab instances for OSS projects, reality paints a different picture

Still unconvinced. You really don't need anything beyond a static site to effectively share information.

Another point you're missing is that there's a 3rd group of people sharing content: experts who are there to establish their expertise. Small companies and individuals generate the highest quality content these days. I work on a blog for our SAAS company and it has been a great success in terms of organic growth (even people coming from LLMs) and to simply establish authority and signal expertise in the field. I can imagine a future where this is majority of expert content on the web and it seems quite sustainable imo.

> blocking AI will mean blocking most people too

If that's websites want, they should have that option.

What are you even talking about?

robots.txt is not a security mechanism, and it doesn’t “control bots.” It’s a voluntary convention mainly followed by well behaved search engine crawlers like Google and ignored by everything else.

If you’re relying on robots.txt to prevent access from non human users, you’re fundamentally misunderstanding its purpose. It’s a polite request to crawlers, not an enforcement mechanism against any and all forms of automated access.

The AI isn't "reading the web" though, they are reading the top hits on the search results, and are free-riding on the access that Google/Bing gets in order to provide actual user traffic to their sites. Many webmasters specifically opt their pages out of being in the search results (via robots.txt and/or "noindex" directives) when they believe the cost/benefit of the bot traffic isn't worth the user traffic they may get from being in the search results.

One of my websites that gets a decent amount of traffic has pretty close to a 1-1 ratio of Googlebot accesses compared to real user traffic referred from Google. As a webmaster I'm happy with this and continue to allow Google to access the site.

If ChatGPT is giving my website a ratio of 100 bot accesses (or more) compared to 1 actual user sent to my site, I very much should have to right to decline their access.

> If ChatGPT is giving my website a ratio of 100 bot accesses (or more) compared to 1 actual user sent to my site

are you trying to collect ad revenue from the actual users? otherwise a chatbot reading your page because it found it by searching google and then relaying the info, with a link, to the user who asked for it seems reasonable

While yes, I am attempting to collect ad revenue from users, and yes, I don't want somebody competing with me and cutting me out the loop, a large part of it is controlling my content. I'm not arguing whether the AI chatbot has the legal right to access the page, I'm not a legal scholar. What I'm saying is that the leading search engines also have the equal rights to access whatever content they want, and yet they all give webmasters the following tools:

- Ability to prevent their crawlers from accessing URLs via robots.txt

- Ability to prevent a page from being indexed on the internet (noindex tag)

- Ability to remove existing pages that you don't want indexed (webmaster tools)

- Ability to remove an entire domain from the search engine (webmaster tools)

It is really impolite for the AI chatbots to go around and flout all these existing conventions because they know that webmasters would restrict their access because it's much less beneficial than it is for existing search engines.

In the long run, all this is going to lead to is more anti-bot countermeasures, more content behind logins (which can have legally binding anti-AI access restrictions) and less new original content. The victim will be all humans who aren't using a chatbot to slightly benefit the ones who are.

And again, I'm not suggesting that AI chatbots should not be allowed to load webpages, just that webmasters should be able to opt out of it.

> While yes, I am attempting to collect ad revenue from users, and yes, I don't want somebody competing with me and cutting me out the loop, a large part of it is controlling my content.

I agree with you about the long run effects on the internet at large, but I still don't understand the horse you have in it personally. I read you as saying (1) it's less about ad revenue than content control, but (2) content control is based on analysis of benefits, i.e. ad revenue?

Well you have no rights when you expose a server to the internet. Other than copyright of course.
> Well you have no rights when you expose a server to the internet.

Technically you don’t, but there are still laws that affect what you can legally do when accessing the web. Beyond the copyright issues that have been outlined by people a lot more qualified than me, I think you could also make the point that AI crawlers actively cause direct and indirect financial harm.

Someday I’ll have enough “karma” to downvote things like this.

The agent should respect robots.txt no matter who is using the Robot.

Do really think LLM vendors that download 80TB+ of data over torrents are going to be labeling their crawler agents correctly and running them out of known datacenters?
Apparently they use smart appliances to scrape websites from residential accounts.
The ones I noticed in my logfiles behave impeccably: retrieve robots.txt every week or so and act on it.

(I noticed Claude, OpenAI and a couple of others whose names were less familiar to me.)

Maybe we need a new "ai.txt" that says "yes I mean you, ChatGPT et. al."
If they don't comply with robots.txt, why would they comply with anything else?
Why wonder. You can test for yourself.
Presumably the crawler that produces whatever index it uses does, which is how it knows what sites to read. Unless you provide it a URL yourself I guess, in which case, it shouldn't.
The LLM shouldn’t.

robots.txt is intended to control recursive fetches. It is not intended to block any and all access.

You can test this out using wget. Fetch a URL with wget. You will see that it only fetches that URL. Now pass it the --recursive flag. It will now fetch that URL, parse the links, fetch robots.txt, then fetch the permitted links. And so on.

wget respects robots.txt. But it doesn’t even bother looking at it if it’s only fetching a single URL because it isn’t acting recursively, so robots.txt does not apply.

The same applies to Claude. Whatever search index they are using, the crawler for that search index needs to respect robots.txt because it’s acting recursively. But when the user asks the LLM to look at web results, it’s just getting a single set of URLs from that index and fetching them – assuming it’s even doing that and not using a cached version. It’s not acting recursively, so robots.txt does not apply.

I know a lot of people want to block any and all AI fetches from their sites, but robots.txt is the wrong mechanism if you want to do that. It’s simply not designed to do that. It is only designed for crawlers, i.e. software that automatically fetches links recursively.

While robots.txt is not there to directly prevent automated requests, it does prevent crawling which is needed for search indices.

Without recursive crawling, it will not possible for a engine to know what are valid urls[1]. They will otherwise either have to brute-force say HEAD calls for all/common string combinations and see if they return 404s or more realistically have to crawl the site to "discover" pages.

The issue of summarizing specific a URL on demand is a different problem[2] and not related to issue at hand of search tools doing crawling at scale and depriving all traffic

Robots.txt does absolutely apply to LLMs engines and search engines equally. All types of engines create indices of some nature (RAG, Inverted Index whatever) by crawling, sometimes LLM enginers have been very aggressive without respecting robots.txt limits, as many webmasters have reported over the last couple of years.

---

[1] Unless published in sitemap.xml of course.

[2] You need to have the unique URL to ask the llm to summarize in the first place, which means you likely visited the page already, while someone sharing a link with you and a tool automatically summarizing the page deprives the webmaster of impressions and thus ad revenue or sales.

This is common usage pattern in messaging apps from Slack to iMessages and been so for a decade or more, also in news aggregators to social media sites, and webmasters have managed to live with this one way or another already.

> it does prevent crawling

No it doesn’t. It politely requests to crawlers that they do not, and if said crawlers choose to honour it than those specific crawlers will not crawl. That’s it. It can and is ignored without penalty or enforcement.

It’s like suggesting that putting a sign in your front yard saying “please don’t rob my house” prevents burglaries.

> Robots.txt does absolutely apply to LLMs engines and search engines equally

No it doesn’t because again, it’s a request system. It applies only to whatever chooses to pay attention to it, and further, decides to abide by any request within it which there is no requirement to do.

From google themselves:

“The instructions in robots.txt files CANNOT ENFORCE crawler behavior to your site; it's up to the crawler to obey them.”

And as already pointed out, there is no requirement a crawler follow them, let alone anything else.

If you want to control access, and you’re using robots.txt, you’ve no idea what you’re doing and probably shouldn’t be in charge of doing it.

> Robots.txt does absolutely apply to LLMs engines and search engines equally.

It does not. It applies to whatever crawler built the search index the LLM accesses, and it would apply to an AI agent using an LLM to work recursively, but it does not apply to the LLM itself or the feature being discussed here.

The rest of your comment seems to just be repeating what I already said:

> Whatever search index they are using, the crawler for that search index needs to respect robots.txt because it’s acting recursively. But when the user asks the LLM to look at web results, it’s just getting a single set of URLs from that index and fetching them – assuming it’s even doing that and not using a cached version. It’s not acting recursively, so robots.txt does not apply.

There is a difference between an LLM, an index that it consults, and the crawler that builds that index, and I was drawing that distinction. You can’t just lump an LLM into the same category, because it’s doing a different thing.

> It does not.

Yes it does. I am the one controlling robots.txt on my server. I can put whatever user agent I want into my robots.txt, and I can block as much of my page as I want to it.

People can argue semantics as much as they want...in the end, site admins decide what's in robots.txt and what isn't.

And if people believe they can just ignore them, they are right, they can. But they are gonna find it rather difficult to ignore when fail2ban starts dropping their packets with no reply ;-)

Any information on what search engine is powering it?
kagi already lets me use claude to search the web. how is this different?
kagi is searching the web for you, and then injecting the results into the context of the prompt.
Are there any downsides to that approach? It seems like we're moving towards empowering llm's to interact with stuff as if that's better than us doing it for them - is it really?

Eg say I want to build an agent to make decisions, shall I write some code to insert the data that informs the decision into the prompt, return structured data, and then write code to implement the decision?

Or should I empower the llm do those things with function calls?

If you want deeper search, it needs to be able to iterate, plan, reason while searching.
Aside, does anyone know of an app like Perplexity for surfing the news in a foreign language (language practice)?

Perplexity's "Explore" tab translates its news to your local language, and its curated news items are all pretty interesting, but the problem is that there are so few of them. I seem to get maybe a dozen stories in a day. I paid their subscription for a month just to listen to the news on my walk, but didn't renew because of this.

A foreign news site like BBC Mundo (Spanish) on the other hand barely has any stories outside of a few niches. Its tech section only has a few stories per week.

Hmm, maybe I want a sort of RSS reader that AI-translates stories for me. But I don't really want to maintain a feed myself either.

Apple News would probably do it since they also have good curation, but afaict they still don't support foreign news sources (why???).

Use a VPN to appear like being in the target country. Use a browser profile where you set the language preference to the one you target.
For which purpose?

ground.news includes sources from all sorts of countries, and also auto-translate headline and the intro, while you can still click to access the source article. Not affiliated, just happy user.

Example with sources in English, German and French: https://ground.news/article/accident-on-the-a13-in-the-yveli...

Although I'm not sure how useful it is for language learning, as you cannot (afaik) configure it to only display articles in Spanish or something similar, but if you filter by stories about France, you'll get a lot of French sources (obviously).

What's up with the geoblocking of Claude features? Not the first time it happens
Different geographies have different legal requirements.
ask the same geniuses who gave you the browser cookie popup re-implemented in a new way on every fucking website ever
Does not really say /how/ it's performing a web search... Is it tapping into it's "own" corpus of material or calling out to some other web search engine?
In my quick experiment (asking a question that would naturally lead to content on my own site) it is not doing a real time request to the site in question. Its answer included links back to my site (and relevant summaries), but there was no requests for those pages while it was generating its answer. So it's clearly drawing from info that has already been scraped at some earlier point. And given that I see Claudebot routinely (and politely) crawling the site I'd guess it's working from it's own scraped copies (because why use someone else's if you've got your own....)
Major AI players don’t want to use someone else web index as they may cut it off or jack up the prices etc. major players want to build their own web index
And this is why we see our logs overloaded with ABot BBot CBot etc, every single "AI" company makes their own bot and they all crawl the same pages over and over.
There is already a 100 ways of doing it using MCP

https://glama.ai/mcp/servers?searchTerm=search

What's the benefit of bringing native integration?

The native app that allows for MCP is only available officially on Mac's and the web interface is generally more convenient for non-technical users. Searching and interacting with the web has become a table-stakes feature and was a glaring gap in Claude.
Let me rephrase it.

MCP has the capability to add this functionality.

It would be nice to see MCP getting adoption in their web UI, as well easier UX, rather than more ad hoc features being added natively.

This is likely implemented behind the scenes as an MCP server exposed to their model in the web UI. It is likely that they will enable MCP servers over HTTP+SSEs (vs the stdin/stdout used with Claude desktop) on the web version in the near future.
Good news. I integrated Claude with a scrapper to get info from pages and it was not giving hallucinations 99% of the time. Hope this works out of the box now.
Funny thing is that I have the obsidian-mcp-tools installed and today claude-desktop just starting fetching stuff from the web through that because it exposes a fetch tool to claude.

So this limitation is a bit arbitrary anyway.

Awesome, but I also do want to say it’s pretty sad it took this long straight up. Literally no excuse. But I’m glad they finally got to a feature that was launched more than a year ago on competitors.
I haven't used Claude yet, but heard many good things. So I'm surprised to see that they're so far behind on this feature.

These are interesting times.

It wasn't long ago that a uni senior who worked for a decade+ on Google Search told me that it was hopeless anyone tries to compete with Google not because it sees a tonne of signals that helps with IR but because of its in-house AI/ML.

It turns out that the org that built the ultimate AI/ML that runs rings around anything that came before it for NLP (and thus IR) was a sister team at Google Translate.

It isn't inconceivable that a kid might be able to build a Google-quality web search, scalability aside, on CommonsCrawls data in a weekend. As someone who built re-ranking algorithms for a search engine built atop Yahoo! and Wikipedia (REST/SOAP) APIs back in the late 2000s as a side project (and experienced the launch and subsequent iterations of Echo/Alexa up close at Amazon), the current capabilities (of even the open weight multi-modal models) seem too good to be true.

Google itself though is saved by its enormous distribution advantages afforded by Chrome (3B to 5B users) and Android (3B+), aside from its search deals with Apple and other browser vendors.

I’ll be interested in trying it. My admittedly limited experience with this on ChatGPT has been disappointing. ChatGPT falls for the SEO content that has taken over the web.

As an example, I recently travelled abroad to a popular vacationing spot and asked ChatGPT for local recommendations on what to do. When it gave me answers directly, they were pretty solid. But when it “searched the web” instead, the answers were awful. Every single result it suggested had terrible ratings. It did this repeatedly. One of those times I asked it to pick something with better ratings and it sort of improved but not by much.

Of course this is another tool and maybe Claude uses better sources or a better algorithm, but in this case where there was a concrete number tied to the results, that while not perfect, aims to rate the quality of a result, it still did not filter out low quality answers. I’m not sure I trust these LLMs to do any better when there aren’t such ratings available. The available input data is just not very good, and now LLMs are being used to feed that low quality, SEO machine.

thats great - the web he has been trained on or the one from Google?
It's like a line of platforms waiting for their own agents for web search
Is there a way to access the new web browsing capability via API?
Not yet, and no hints as to whether that will happen or not.
Is no one concerned about LLMs just feeding people SEO ads as content?
