What is PR Review Tool?

A tool whose primary surface is the pull request: it reads the diff in context and leaves review comments, usually AI-generated.

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.
