🧐 Turn your Laptop into a Powerful RAG System
LEANN is a lightweight, privacy-first retrieval system that indexes and searches millions of documents while using 97% less storage than traditional solutions without losing accuracy.
It avoids storing all embeddings by using graph-based selective recomputation with high-degree preserving pruning and computes embeddings only when needed.
Key Features:
  • Privacy-first: Everything runs locally, no cloud dependencies.
  • Lightweight: Graph pruning + CSR format minimize storage and memory.
  • Portable: Easily move knowledge bases across devices.
  • Scalable: Handles messy personal and agent-generated data.
  • Accurate: Matches heavyweight vector DBs while using a fraction of the storage.
It’s 100% open-source so check it out!
