Brain
A personal AI memory: search and chat with years of your notes and chats, on your machine.
Years of AI conversations and thousands of personal notes are write-only memory: you cannot ask your past self anything. Cloud "memory" features lock that knowledge into a vendor, in one language, with no control over storage.
Brain turns that scattered history into a private, queryable memory: it ingests your chat exports and notes, organizes them and lets you chat with them in natural language —finding what is relevant by meaning, not keyword—, all on your own machine and in a single program to install.
