ContextBrain is a small, opinionated team building the missing layer between your codebase and your AI tools. Most "AI for devs" products treat code as the only context. We disagree: designs, meetings, tickets, and PR threads carry as much signal as the diff itself — and the team has roles other than developer.
We started this because every team we worked with had the same pattern: context lives everywhere except the place it's needed. So we built one graph for all of it, made it role-aware, made every answer carry citations, and made the whole thing self-hostable on Postgres alone.
The product is built in public, one phase at a time. The phase docs at docs/phases/ are the source of truth — and ContextBrain itself reads them to generate this site's docs, help articles, and changelog.
What we believe
- Citations beat hallucinations, always.
- Roles matter — same product, different windows.
- Self-host is a feature, not a fallback.
- Postgres until proven otherwise.
- Show the work — every phase, every audit, in the open.
