# AI code review tools

> Coding agents now write more code than any team can read. These tools read it first. All six comment on pull requests, and most also review before the PR: in your IDE, your terminal or inside the agent's own loop. Where they differ is which Git hosts they cover and how they bill: per seat, per credit or per review.

6 tools, in the order they appear in the Digidle Tools directory. This is not a ranking.
