How it works
CodeBase Brain learns from the work your team is already doing — no new habits required, no manual documentation.
Authorize CodeBase Brain to read your GitHub repositories and Slack engineering channels. Takes under 5 minutes. No code changes required.
GitHub · Slack · JiraCodeBase Brain processes every PR, code review, and technical Slack thread — extracting the reasoning behind each decision automatically.

Natural language · Cited sourcesFeatures
Four tools in one — each solving a different moment in the developer knowledge lifecycle.
Ask any question about your codebase in plain English. CodeBase Brain searches all indexed PRs, Slack threads, and code reviews to deliver sourced answers in seconds.
Core featureSee exactly which modules are dangerously understood by only one person. Color-coded risk levels, updated weekly from your git history.
Risk managementWhen a developer gives notice, AI interviews them about every module they own — turning 30 minutes into a complete structured handover document.
Knowledge transferEvery GitHub PR automatically shows related past decisions in a sidebar — so developers never unknowingly undo something tried and rejected before.
GitHub nativeEarly feedback
"We lost three senior engineers last quarter. CodeBase Brain meant our team could answer 'why' questions in seconds instead of weeks of archaeology."
"The bus factor dashboard alone was worth it. I had no idea 60% of our payment service was understood by exactly one person. We fixed that immediately."
"New developers used to take 3 months to feel confident. With CodeBase Brain they're contributing meaningful PRs by week two."
