Pith is a local-first desktop LLM knowledge base that replaces vector databases with a hybrid retrieval approach of weighted keyword search and link-graph traversal. It hydrates documents (PDFs, emails, notes) into dense Markdown entries, enabling chat-based interaction with your entire library while keeping everything in plain files. Its innovative combination of LLM-based hydration with traditional retrieval methods offers a transparent, debuggable alternative to opaque embedding-based systems.
Target audience: backed devs, data engineers, knowledge workers
