HyperbookLM - an open-source NotebookLM alternative with a web agent. You can add URLs and it browses, reads, and remembers everything. Then ask questions across all your sources, generate audio summaries, create mind maps, or export to slides. Powered by Hyperbrowser and GPT-5.2. Coming soon as open-source.

@hyperbrowser HyperBookLM is now live here:

@hyperbrowser Looking forward to checking it out!

The key takeaway is how fluidly the web agent is able to deploy the cutting-edge power of GPT-5.2. This combo proves that the 'search and synthesis' layer is instantly being commoditized. The new battleground for user lock-in won't be the LLM, but which Agent can flawlessly connect the dots across complex, real-time web data to deliver unbeatable strategic analysis.

@hyperbrowser the podcast should be generated locally

@hyperbrowser You should better post it when "Coming soon as open-source." is ready 🙂

@hyperbrowser Does it generate mindmaps?

@hyperbrowser Open source is winning

@hyperbrowser no, thanks! @NotebookLM is simply better. why settle for something less?

@hyperbrowser How can I test it?

@hyperbrowser Ye to drop.. I will let you know when it's out.. Keep an eye.

@hyperbrowser The podcast and stuff generated using gemini?

@hyperbrowser Sounds like a solid alternative to NotebookLM. Hope it's as simple and effective as it seems. Can't wait to try it out!

@hyperbrowser I've tested HyperbookLM; it works as advertised.

@hyperbrowser that’s why we build

@hyperbrowser Thank you for sharing ! The only missing piece is video but excellent alternative indeed

@hyperbrowser Bold move teasing this without a link. If you drop a rough alpha or repo, even half-baked, people will line up to test it for you.

@hyperbrowser DOES IT PROVIDE API?

@hyperbrowser Open source NotebookLM rivals are here

@hyperbrowser Persistent memory across URLs plus a web agent changes it from a note taking app into a real research workspace. The ability to query everything, generate audio summaries, and move straight into mind maps or slides is where leverage comes from.

@hyperbrowser nice find with the hyperbooklm! what kind of use cases do you have in mind for this web agent, or are you using it for anything specific already?

@hyperbrowser the audio summary in these is a one-shot export, you re-run it each time the source changes. for a GitHub repo shipping daily, an always-on feed that re-summarizes new commits and PRs into RSS, like Podlog, matches the cadence better. written with s4lai

@hyperbrowser lol why would you want an open book alternative when the original is basically free.

@hyperbrowser Oh

@hyperbrowser Thanks you just got yourself a new follower.

@hyperbrowser Interesting, a web agent for NotebookLM is an intriguing direction.

@hyperbrowser Looks like it can really streamline research workflows. Curious how it handles different content types and formats.

@hyperbrowser broskis add text files plzzzzz

@hyperbrowser HyperbookLM is a game-changer for researchers. Web browsing meets knowledge synthesis
