firecrawl
🔥 Turn entire websites into LLM-ready markdown or structured data. Scrape, crawl and extract with a single API.
If you want to build your own end-to-end crawling and scraping infrastructure (expert users only), developers typically use Playwright, a Microsoft framework for web testing and automation. Playwright Web Scraping is a reliable open-source web scraping implementation using Playwright. Firecrawl is also open source and lets you host it in your own infrastructure if you want absolute control.

I tried years ago, I don't think I got it working, ended up using Rhasspy/voice2json instead (TIL: the creator of both is now the Voice Eng Lead for Home Assistant).
Looks like the GitHub is still somewhat active, although their roadmap links to a dead Trello: https://github.com/leon-ai/leon

deep-research
An AI-powered research assistant that performs iterative, deep research on any topic by combining search engines, web scraping, and large language models. The goal of this repo is to provide the simplest implementation of a deep research agent - e.g. an agent that can refine its research direction overtime and deep dive into a topic.
As of now—literally today they announced—OpenAI gives 10 queries of Deep Research per month for Plus users. I wanted to create an alternative, so I took inspiration from this repository https://github.com/dzhng/deep-research but didn’t want to pay for the Firecrawl API too. Instead, I used algorithm from that repository. Here’s the result: https://github.com/jolovicdev/shandu. It’s still rough around the edges—things like proxy support for rate limits aren’t fully implemented yet—but it’s functional! You can try it out with a model you’re running in LM Studio. I’m not entirely sure if this is the best way to build something like this (arch wise, especially since I haven’t worked with LangChain or LangGraph), but here it is - built with a little help from Grok and DeepSeek!
Compared to dzhng/deep-research, which relies on the Firecrawl API (and its costs), Shandu skips that entirely and uses the same core algorithm in a simpler, free setup (integrated scraper). It’s less polished and missing some features (like proper rate limit handling), but it’s a lightweight option you can run locally without subscriptions.
I’d love for you to check it out, maybe give it a star if you like it, or drop some feedback if you’ve got suggestions, because there are probably some community tools that I could have used, or some other direction generally. I think it’s a solid starting point.

Here's the thing. I want a personalized AI. Full stop.
There's no arguing back and forth.
Tech is here someone needs to put it together.
I'm so busy with other things, but I really want to see this thing come through and happy to work on it.
To me, its insane Apple didn't figure it out.
The goal: Build a truly personalized AI.
- Single threaded conversation with an index about everything.
- Bot should be accessible via WhatsApp, Insta, Email, or a phone call through an app (WebRTC connection).
(https://botpress.com/ is a really good starting point).
- Operator at the back that has login access to almost all tools I use, but critical actions must have HITL.
- Bot should be accessible via a call on the app or Apple Watch.
https://sesame.com/ type model and this is very doable with https://docs.pipecat.ai especially their new release that allows for long running function calls.
Speech detection (VAD) is still a problem, but I think its more of systems engineering problem than ML problem. Interruptions need to feel smooth.
But this is not a blocker. What exists is good enough.
- It can should be able to digest images, voice notes, etc.
- everything should fall into a single personal index (vector db).
One of the things could be, sharing 4 amazon links of some books I want to read and sending those links over WhatsApp to this agent.
It finds the PDFs for the books from https://libgen.is and indexes it.
I phone call the AI and I can have an intelligent conversation about the subject matter with my AI about the topic.
I do this a lot with xAI's Grok and its a surprisingly effective tool.
I give zero fucks about issues like piracy at the moment.
I want to later add more capable agents as tools to this AI.

Yjs is nice. Easy to get p2p results.
Yjs backend, its persistence and eventual complict resolution(one of editors stayed too long offline) seems like a tough to crack an issue.
Always wanted to have a nice experience with block editor like Platejs https://platejs.org/
There is a nice attempts simplify dev experience with solutions like Liveblocks https://liveblocks.io/text-editor However most options come at the expense of controlling your data.
CRDT keyword search on HN bring consistently good results and interest in the topic, but no good options on open source backend side. Check it many times in the past. Please correct me if I missed something.
https://hn.algolia.com/?dateRange=pastYear&page=0&prefix=tru...
Editing complex documents with Yjs and editors like Platejs which can represent data in JSON seems like a tough challenge, and most people expectations it should work at least as in Google Docs or Notion.
