What does SurfSense do?

SurfSense is an open-source platform that acts as a central knowledge hub for teams. It connects to your existing data sources like Notion, Google Drive, and Gmail, syncing your documents and allowing you to chat with them using AI. The system transforms your team's collective knowledge into an interactive, searchable resource where you can ask questions and get answers with citations from your own materials.

What sets SurfSense apart is its flexibility in AI model selection. Instead of being locked into one AI, you can choose from more than 100 different large language models. For teams with specific security or privacy needs, it supports running models locally using popular frameworks like vLLM, Ollama, and llama.cpp. The platform is built for real-time collaboration, letting multiple team members work together simultaneously on the same documents with live edits and presence indicators.

This tool is particularly valuable for development teams, remote work groups, and any organization that needs to make better use of their internal knowledge. Use cases include creating a centralized Q&A system for company documentation, enabling collaborative research projects where team members can ask questions about shared materials, and building a multiplayer workspace for analyzing and discussing internal documents with AI assistance.
