Guided Review

Guided Review is a free and open-source code review tool for developers who still need to understand AI-generated changes before approving them. It turns a raw Git diff into an ordered walkthrough, grouping related hunks into review units so you can review a change’s schema, logic, call sites, and tests together instead of scrolling an alphabetical file list.

Use the Chrome extension on GitHub pull requests, or run the CLI to review a local branch, commit, or working-tree diff before a PR exists. Guided Review displays the real parsed diff in a keyboard-first overlay, lets you move through units, search changes, and draft line comments. On GitHub, you can submit those comments through the normal review flow. In the CLI, notes stay local and can be turned into a prompt for a coding agent.

AI is used to structure the review, not to replace the reviewer. With your own Anthropic, OpenAI, or Grok key, Guided Review groups real diff hunks and adds short commentary. The model never provides the code shown in the interface: every displayed line comes from the actual diff, and invalid model references are discarded. Without a provider, Guided Review still offers a file-by-file walkthrough.

Guided Review has no product backend. Your diff is sent only to the AI provider you choose, and the Chrome extension sends data to GitHub only when needed for PR access or a review you explicitly submit. API keys, review sessions, and drafts remain on your machine.
