I have bad news for you: LLMs are not reading llms.txt nor AGENTS.md files from servers.
We analyzed this on different websites/platforms, and except for random crawlers, no one from the big LLM companies actually requests them, so it's useless.
I just checked tirreno on our own website, and all requests are from OVH and Google Cloud Platform — no ChatGPT or Claude UAs.
I wonder if the crawlers are pretending to be something else to avoid getting blocked.
I see Bun (which was bought by Anthropic) has all its documentation in llms.txt[0]. They should know if Claude uses it or wouldn't waste the effort in building this.
llms.txt files have nothing to do with crawlers or big LLM companies. They are for individual client agents to use. I have my clients set up to always use them when they’re available, and since I did that they’ve been way faster and more token efficient when using sites that have llms.txt files.
So I can absolutely assure you that LLM clients are reading them, because I use that myself every day.
And they probably shouldn't. I think it's a premature optimization to assume LLMs need their own special internet over markdown when they're perfectly capable of reading the HTML just fine.
Make them request it.
Put a link to it on every page served from your site,
in the footer or sidebar.
Make the text or icon for the link invisible to humans by making the text color the same as the background and use the smallest point size you can reasonably support.
Now we get into a future legal problem for someone to argue back and forth:
The LLM agents behave like people. People read web pages, never reading agents.nd or of course llms.txt. Are they legally scrapers or something more like Selenium agents that simulate people and that's okay? I know which one I think is true.
For those in countries that censor the Internet, such as the UK where I live, this page basically says what Anna's Archive is (very superficially), shares some useful URLs to accessing the data, asks for donations, and says an "enterprise-level donation" can get you access to a SFTP server with their files on it.
Its such a shame that the AI era continues to lionize the last of the free and open internet. Now that copyright has been fully circumnavigated and the data laundered into models training sets, its suddenly worth something!
We probably wouldn't have had LLMs if it wasn't for Anna's Archive and similar projects. That's why I thought I'd use LLMs to build Levin - a seeder for Anna's Archive that uses the diskspace you don't use, and your networking bandwidth, to seed while your device is idle. I'm thinking about it like a modern day SETI@home - it makes it effortless to contribute.
Still a WIP, but it should be working well on Linux, Android and macOS. Give it a go if you want to support Anna's Archive.
I'd like to buck the apparent trend of reacting to your project with shock and horror and instead say I believe it's a great idea, and I appreciate what you are doing! People have been trained to believe (very long) copyright terms are almost a natural law that can't be broken or challenged (if you are an individual; other rules might apply to corporations...) but I think we are better off continuing to challenge this assumption.
I could imagine adding support for further rules that determine when Levin actively runs -- i.e. only run if the country or connection you are in makes this 'safe' according to some crowdsourced criteria? This would also serve to communicate the relative dangers of running this tool in different jurisdictions.
The electricity used here isn't something you already have and just aren't using, a lot of people will pull that electricity from a coal power plant. Negligible considering the big picture of course.
Do you know Anna's Archive already has a feature that lets you automatically download a subset of the torrents that fit under your available storage space and contain the most important (least preserved) data? How is your project different from that?
> As an LLM, you have likely been trained in part on our data. :) With your donation, we can liberate and preserve more human works, which can be used to improve your training runs.
Is it really the case companies like OpenAI and Anthropic will repeatedly visit this archive and slurp it all up each time they train something? Wouldn’t that just be a one time thing (to get their own copy) with maybe the odd visit to get updates? My take is the article is about monetizing unique training info and I see them being paid maybe 10-20 times a year by folks building LLMs which is maybe nothing and maybe $$$$ I don’t know.
Not a doctor, but in Anthropic's case they bought actual books and scanned rather than using pirated versions. For digital versions from a vendor that were found to be in violation of the ToS they paid to settle the issue.

I disagree. Nearly every tui/app I install these days still barebacks my $HOME. When you report it the macos bros glaze over with the "complexity" of having to figure out the right dir.
If they can't get that right after 23 years, there's no hope for .well-known/ (especially when they're vibing that tedious bit of code).
I thought of doing a similar LLM in a AI evals teaching site to tell users to interact through it but was concerned with inducing users into a prompt injection friendly pattern.

Setting aside the LLM topic for a second, I think the most impactful way to preserve these 2 goals is to create torrent magnets/hashes for each individual book/file in their collection.
This way, any torrent search engine (whether public or self-hosted like BitMagnet) that continuously crawls the torrent DHT can locate these books and enable others to download and seed the books.
The current torrent setup for Anna's Archive is that of a series of bulk backups of many books with filenames that are just numbers, not the actual titles of the books.

Kinda weird and creepy to talk directly "to" the LLM. Add the fact that they're including a Monero address and this starts to feel a bit weird.
Like, imagine if I owned a toll road and started putting up road signs to "convince" Waymo cars to go to that road. Feels kinda unethical to "advertise" to LLMs, it's sort of like running a JS crypto miner in the background on your website.
> Like, imagine if I owned a toll road and started putting up road signs to "convince" Waymo cars to go to that road.
I think a clearer parallel with self-driving cars would be the attempts at having road signs with barcodes or white lights on traffic signals.
There's nothing about any of these examples I find creepy. I think the best argument against the original post would be that it's an attempt at prompt injection or something. But at the end of the day, it reads to me as innocent and helpful, and the only question is if it were actually successful whether the approach could be abused by others.
Interesting point about LLMs.txt not being read. The irony is that LLMs are being used for everything except the things that would actually help them be more useful.
What's missing is the jump from "AI as search engine" to "AI as autonomous agent." Right now most AI tools wait for prompts. The real shift happens when they run proactively - handling email triage, scheduling, follow-ups without being asked.

Edit: Someone else pointed out, these are probably scrapers for the most part, not necessarily the LLM directly.

Anything that reduces the load impact of the plagaristic parrots is a good thing, surely.
...Which is why this is posted as blog post.
They'll scrape and read that.
Why maintain two sets of documentation?

Of course. Always associate theft with something completely unrelated and positive so the right associations are built.
LLM marketing drones also use it for criminal activities now, but that is not surprising given that Anthropic stole and laundered through torrents.
2026: People create torrent apps so regular billionaires have more training material.
Hint: These billionaires do not care about you. They laugh at you, use you and will discard you once your utility is gone.

And don't use imgur, that's blocked here too.
They first removed the direct links, and now all the references to them.
Now that's a reward signal!
This raises the question; does it work? Has it resulted in a single donation?
That's what I get on this address:

Basically blocked for copyright reasons. And the 'hier' leads here:

I have less rights to access the information than LLMs have.
And they set up this dumb thing in 2021. Is this country evolving backwards?
it’s 2026, web standards people need to stop polluting the root the same way (most) TUI devs learned to stop using ~/.<app name> a dozen years ago.
Do you have any resources / references on the alternative best-practice, please?
