What is GBrain?

Your AI agent is smart but it doesn't know anything about your life. GBrain fixes that. Meetings, emails, tweets, calendar events, voice calls, original ideas... all of it flows into a searchable knowledge base that your agent reads before every response and writes to after every conversation. The agent gets smarter every day.

~30 minutes to a fully working brain. Your agent does the work. Database ready in 2 seconds (PGLite, no server). Schema, import, embeddings, and integrations take 15-30 minutes depending on brain size. You just answer questions about API keys.

Requires a frontier model. Tested with Claude Opus 4.6 and GPT-5.4 Thinking. Likely to break with smaller models.
