Understand what the AI built
AI investigates.You decide.
AI can write a change in seconds. PR Review Buddy helps you understand what it actually did, how the pieces fit together and where to look more closely before you decide whether it should merge.

AI should improve reviewers, not replace them.
AI can write a change, review it and suggest the fix. You are still the one answering for what enters the codebase. Great reviews start with understanding what actually changed, then asking the right questions and investigating when it matters. PR Review Buddy helps you do exactly that.
AI reviews the PR
- ✓Finds issues
- ✓Gives a verdict
- ✓Suggests fixes
You consume the output.
You review the PR
- ✓Maps the change into understandable themes
- ✓Explains how the pieces relate
- ✓Shows where risk and uncertainty sit
- ✓Gives you questions and evidence to investigate
You understand the change, and you decide.
Two ways to start your guided review
Pick the experience that fits your workflow. Both help you understand and challenge a change before you decide whether it should merge; they differ only in where you start and where you read it.
CLI
Start where you already work
Run one command in your terminal. The analysis happens in an isolated checkout, so your working tree is never touched and you carry on working while it runs. A review workspace opens in your browser when it is ready.
$ prreviewbuddy review ✓ Prepared isolated checkout ✓ Read what changed ✓ Read pull request conversation ⠻ Analysing the change Review ready at http://127.0.0.1:7420/r/8f3c…Chrome extension
Review in your browser
Stay on GitHub. The review opens in a sidebar beside the diff, tied to the files and lines it is about, so you never lose your place in the pull request you are already looking at.

Not sure? Start with the CLI if you have Claude Code, Codex CLI or Gemini CLI installed.
How it works
A guided workflow that helps you review the right things, in the right order.
Understand
The change is read and grouped into themes, in a suggested order, so you build a mental model of code you may not have written.
Focus
Overall risk, potential issues and the questions worth asking are surfaced before you open a single file.
Investigate
Dive into files and findings with your own AI beside you, reading the repository rather than guessing at it.
Decide
You mark what you have judged and what is still open. The verdict is yours; nothing is approved or posted on your behalf.
KISS lens · CLI
AI makes writing code cheap. Complexity is still expensive.
A generated solution can be correct, pass its tests, and still leave behind more abstraction, indirection and configuration than the problem ever needed. The KISS lens, named for the classic “keep it simple” principle, is a second pass over the same change that asks only that question.
What was introduced
Named concretely, never “this is complicated”.
Evidence in this change
What in the diff shows it. Tied to the change, not the repository.
Why the requirements do not call for it
The argument that this problem does not need this much.
A simpler direction
A materially simpler implementation, or there is no recommendation.
It also reports the complexity it decided is worth keeping, and why. The standard is not fewer lines. It is no more complexity than the problem requires.
Built for developers who take reviews seriously
No account, no API key
Nothing to sign up for and no credential to hand over.
Private by default
Reviews stay on your machine. There is no server of ours in the loop.
Use your own coding agent
Claude Code, Codex CLI or Gemini CLI, using the sign-in you already have.
Made by reviewers
Built for the person doing the reviewing, not to replace them.
Understand the change before you approve it.
Choose the route that fits how you work, and start your first guided review.
