What´s gBrain and how does it work?
I’ve been using gStack for a while when ideating, validating new projects, and some coding
now I’m experimenting with gBrain as the memory layer for my agents, starting with my Hermes Agent company
gBrain is an open-source persistent memory layer for AI agents (by @garrytan). it turns your emails, meetings, tweets, voice memos, and docs into a typed knowledge graph. essentially markdown in, graph out.
how it works:
- ingest signals from your daily life
- extract entities + create typed links (works_at, invested_in, attended)
- store as Markdown + Postgres + pgvector
- retrieve via hybrid search (keyword + vector + graph)
- agents read brain first, write insights back, graph builds itself
an overnight dream cycle dedupes entities, repairs links, and updates the compiled truth
