Everything you need for smarter code review

Not just another linter — CodeSage understands your architecture, conventions, and history.

Codebase-Aware Reviews

Reviews are grounded in your indexed codebase. The AI sees existing implementations, team conventions, and prior findings — not just the diff.

Security & Quality Scoring

Every PR gets a 0-100 quality score across Correctness, Security, Standards, and Reusability. Critical findings are surfaced prominently.

Automatic PR Comments

Connect your GitHub App and CodeSage automatically posts review comments and scores directly on your pull requests.

Semantic Code Search

Search your codebase by meaning, not keywords. Find "database connection pooling" across all implementations instantly.

Learns Your Conventions

Skills capture team-specific patterns and anti-patterns. They're extracted from your codebase and enforced in every review.

Trend Analytics

Track quality scores over time, see recurring issues, monitor cost per review, and measure knowledge base health.
