Features

Everything your team needs to preserve knowledge

Four tools in one — each solving a different moment in the developer knowledge lifecycle.

💬

Knowledge Chat

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 feature
⚠️

Bus Factor Dashboard

See exactly which modules are dangerously understood by only one person. Color-coded risk levels, updated weekly from your git history.

Risk management
🤝

Offboarding Interview

When a developer gives notice, AI interviews them about every module they own — turning 30 minutes into a complete structured handover document.

Knowledge transfer
🔍

PR Context Sidebar

Every GitHub PR automatically shows related past decisions in a sidebar — so developers never unknowingly undo something tried and rejected before.

Early feedback

What engineering leaders are saying

★★★★★

"We lost three senior engineers last quarter. CodeBase Brain meant our team could answer 'why' questions in seconds instead of weeks of archaeology."

SR
Sarah R.
CTO, Series B Fintech
★★★★★

"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."

MK
Marcus K.
VP Engineering, SaaS Platform
★★★★★

"New developers used to take 3 months to feel confident. With CodeBase Brain they're contributing meaningful PRs by week two."
