For those of you who aren't familiar with SurfSense, it aims to be the open-source alternative to NotebookLM, Perplexity, or Glean.
In short, it's a Highly Customizable AI Research Agent but connected to your personal external sources like search engines (Tavily), Slack, Notion, YouTube, GitHub, and more coming soon.
I'll keep this short—here are a few highlights of SurfSense:
📊 Advanced RAG Techniques
- Supports 150+ LLM's
- Supports local Ollama LLM's
- Supports 6000+ Embedding Models
- Works with all major rerankers (Pinecone, Cohere, Flashrank, etc.)
- Uses Hierarchical Indices (2-tiered RAG setup)
- Combines Semantic + Full-Text Search with Reciprocal Rank Fusion (Hybrid Search)
- Offers a RAG-as-a-Service API Backend
ℹ️ External Sources
- Search engines (Tavily)
- Slack
- Notion
- YouTube videos
- GitHub
- ...and more on the way
🔖 Cross-Browser Extension
The SurfSense extension lets you save any dynamic webpage you like. Its main use case is capturing pages that are protected behind authentication.
PS: I’m also looking for contributors!
