Show HN: Zenfetch – Turn your saved browsing content into an AI second brain (zenfetch.com)

56 points by rex123 ↗ HN
Hey everyone! Akash and Gabe here from Zenfetch (YC W23) - a chrome extension to help you remember more of what you read. Zenfetch makes it easy to index any content from across the web into a neural search engine and AI chat. Try the chrome extension at https://www.zenfetch.com/?utm_source=hacker_news.

How it works:

1. Optionally sync your bookmarks and/or Pocket saves. Zenfetch will continue to sync newly saved items. 2. Click the Zenfetch icon in a tab to save any PDF, YouTube video, note, article, email, forum post, etc. Zenfetch can save almost anything across the internet. 3. Zenfetch indexes the text or transcript and adds that information to your AI second brain. 4. Use the dashboard or side panel to search or chat with your AI second brain. 5. Zenfetch will send morning digests summarizing your reading.

A few examples of how our users use Zenfetch: “What articles have I read on nuclear fusion?”, “Analyze this strategy based on the Lenny Rachitsky article I read”, “Summarize Karpathys video introducing LLMs”, “Which research papers mentioned the increase in carbon emissions?”, “Compile the different perspectives I’ve read on climate change” and more.

We built Zenfetch to solve the personal pain of reading tons of content but using little to none of the information. While searching for solutions, we found that most tools were good at storing information but not at retrieving it. We even found that search functionalities on existing read-later tools got worse the more content we saved.

Zenfetch is free for the first 14 days and then costs $14.99/mo (No credit card needed for the trial).

We’d love for you to try it out and let us know what we can do to improve your experience! While we only work on Chromium-based browsers right now, we’re actively working on browser compatibility and integrations. Let us know which ones to prioritize!

I'll quote my old post: https://news.ycombinator.com/item?id=38421121

„My perfect bookmark manager is Markdownload https://github.com/deathau/markdownload Just save the complete page, only selected text or only the link to a markdown file or Obsidian. With downloaded, linked or without pictures. My OS and Obsidian can search those files, they have more (automatically added) metadata. I can even edit them in the browser: add your thoughts, tags or change the name of the file before they are saved. I can (automatically) do with them what ever I need. They can be used to (automatically) generate an always up to date start page or a data vault on GitHub. My local AI assistant can parse them. Local, versatile, permanent, flexible, cost effective, future save. No need for a bookmark manager.“

Howdy, Gabe from Zenfetch here.

Thanks for sharing this, markdownload looks super useful. I use obsidian myself and have tried a few bookmarks managers. They are all great, though I often find myself forgetting information from a few months back unless I actively build networked thought.

We built Zenfetch so that I can offload that work and have Zenfetch remind me of important information when I need it. Today that's done through emails and remind me prompts, and we have plans for helping recall more information in the near future :D

Have you seen arcs search? Its one of my favorite feature where cmd + f seamlessly transitions to AI chat when it doesn't find the text directly. seems like a +1 if cmd + f seamlessly transitions from direct text -> ai chat -> search some bookmarks. Is that the goal here?
gabev
Definitely the right direction!

Zenfetch offers the ability to chat with a webpage, like Arc, while also pulling in references from your previously saved content. These references are used to augment the answer to the question.

The goal is to help reinforce material you've read in the past and form associations with current learnings.

This is actually really cool, especially the takeaways. Tried it on a YouTube video and works like a charm

This seems interesting! How are you dealing with hallucination? e.g. recalling a fact from an article that I have not necessarily read
rex123
Hey, Akash from Zenfetch here. Fair question. As with any LLM based product, we can't guarantee there won't be any hallucinations. Empirically, we've seen very few instances. We have checkers in place to reduce the risk, and always cite the source material as an escape hatch so you can see where information came from

I watch a bunch of MIT OCW classes on youtube. Is there a limit on how long the Youtube videos can be in order to save?

Have been using Zenfetch and has come in handy so many times when I want to get the gist of articles or explore connections.

A happy user here!

Been using Zenfetch for a while now & it's only improved based on user feedback. Great product.

Can Zenfetch work with paywalled content?

This looks great! Loving the product. Does this store information from videos that I've watched as well?

I Would love to see self hosted option either with local LLMs or self API keys. Privacy and longevity of the project would be the main points for such an initiative. Cool project either way!

I love the idea. I signed up and now I'd like to import a bunch of bookmarks I have stored in Evernote and Obsidian over the years. I can't find a way to do this though. Is there a way to import all of these?

I suppose I could try the Chrome bookmarks importer if I can import everything into chrome. But I can't find the import option after the initial signup workflow.
