gbrain

My second brain: a Postgres and pgvector knowledge base of everything I work on, synced every day, that my agents search first.

How it works

Everything I work on lands in one knowledge base: project files, meeting notes, voice notes. A routine syncs it every morning and my agents search it before they answer, so they start with context instead of from zero.
