What is a PR review tool?

PR review tools sit on the merge step rather than the whole repository. They read a diff alongside surrounding code, related files and often issue-tracker context, then post line-level comments the way a human reviewer would.

Unlike a linter, the output is argued rather than pattern-matched, which is also the risk. These tools trade determinism for context, so the practical questions are comment precision, how much reviewer time they actually save, and whether developers start ignoring them.

What to look for

• Signal-to-noise on real pull requests during a trial, not on a demo repository
• Whether the tool learns from resolved or dismissed comments
• How much repository context it reads beyond the diff itself
• Whether it can block a merge or only comment
