Frequently Asked Questions

What is an AI code reviewer?

A tool that reads a pull request, often with context from the wider repository, and posts comments about bugs, security issues and style, so human reviewers can focus on design and intent.

Why does codebase context matter?

A diff shows only changed lines. Catching what a change breaks elsewhere needs the surrounding repository, which is why context layers such as Sourcegraph and Graphify are listed separately.

Can AI replace human code review?

Not reliably. AI reviewers catch many routine problems quickly, but people still judge design, intent and risk, so most teams use both.

Which tools were added or changed?

The original four (Greptile, CodeRabbit, Sourcegraph, Graphify) are kept. The page now also covers other AI reviewers, platform-native review and quality platforms with AI review.

Are the links checked?

Links were checked when this page was updated. I did not re-verify the feature claims from the earlier version of this page, so the cards stay general.
