LEANN: Efficient Vector Database for RAG Systems

LEANN is an innovative vector database designed to enable users to implement retrieval-augmented generation (RAG) systems on personal devices. It provides a solution that allows for the indexing and searching of millions of documents while achieving 97% storage savings compared to traditional methods, all without sacrificing accuracy.

Key features:

• Privacy - User data remains on the device, ensuring complete privacy without reliance on cloud services.
• Lightweight - Utilizes graph-based selective recomputation to minimize storage and memory usage.
• Portable - Facilitates easy transfer of knowledge bases between devices.
• Scalability - Capable of managing large datasets that would typically overwhelm conventional vector databases.
• No Accuracy Loss - Maintains search quality equivalent to heavier solutions while using significantly less storage.

LEANN is particularly suitable for users looking to enhance their personal AI capabilities, enabling semantic searches across various data sources, including documents, emails, and chat histories, all while ensuring privacy and efficiency.
