Open Source Alternative to NotebookLM

For those of you who aren't familiar with SurfSense, SurfSense is an open-source alternative to NotebookLM for teams.

It connects any LLM to your internal knowledge sources, then lets teams chat, comment, and collaborate in real time. Think of it as a team-first research workspace with citations, connectors, and agentic workflows.

I’m looking for contributors. If you’re into AI agents, RAG, search, browser extensions, or open-source research tooling, would love your help.
