Lumi

Lumi gives your AI persistent memory across chats. Start a new Claude or ChatGPT session and it already knows your project, preferences, and history. No re-explaining. No copy-pasting old threads. Store wide, retrieve narrow: upload docs and PDFs, Lumi indexes everything but surfaces only what's relevant per prompt like personal RAG, no setup needed. Cuts token usage on long projects without losing context. Free to start.
