AI code review

Last updated 2 October 2026.

What is AI code review?

AI code review is the use of AI models to read a code change, usually a pull request, and comment on bugs, security problems and risks before a person decides to merge it.

What it typically does

• Reads the diff and the code around it.
• Posts comments on specific lines, ranked by how serious each problem is.
• Summarises the change and how ready it is to merge.
• Runs on every commit, in minutes, at any hour.

Where people still decide

• Whether the change is the right thing to build.
• Whether a finding matters for this product. Good tools let you push back; see replying to a finding.
• The merge itself.
