Getting started with CodeReviewr

Set up CodeReviewr in under 60 seconds and start getting AI-powered code reviews on your pull requests

Get AI code reviews on every pull request. No waiting for reviewers, no context switching, just fast feedback when you need it.

#Sign up with GitHub

Visit codereviewr.app and sign in with GitHub. We use GitHub OAuth—no separate account needed.

#Install the GitHub App

After signing in, go to Settings and click "Install GitHub App." Choose your personal account or organization, then select which repositories to review. Installation takes about 30 seconds.

#Automatic reviews

Create a pull request in any connected repository. CodeReviewr automatically:

  1. Detects the PR via GitHub webhooks
  2. Analyzes the diff using AI
  3. Posts review comments on the PR
  4. Reviews only new changes (incremental reviews stay focused on new changes)

Reviews happen automatically—no setup required beyond installation. You can also trigger reviews manually or chat with the bot as described below.

#Chat and commands

After a review, you can interact with CodeReviewr directly in PR comments by mentioning it:

@codereviewr Why did you flag this as a security issue?

You can also trigger actions with slash commands:

  • /review — manually trigger a full code review
  • /help — see all available commands

#Review categories

Issues are categorized by severity:

  • Critical: Security vulnerabilities, production-breaking bugs
  • High: Major functionality issues, performance problems
  • Medium: Bugs that impact UX, technical debt
  • Low: Code style, minor improvements
  • Info: Suggestions and best practices

Each issue includes the file path, line number, and explanation. CodeReviewr focuses on meaningful problems—security, bugs, performance—not style nitpicks.

#Limitations

CodeReviewr works best for PRs under 300KB of changes. Very large PRs (generated code, massive refactors) may be skipped. Split large changes into smaller PRs anyway—it's better practice.

We currently support GitHub only. Reviews happen automatically and usually complete within seconds for small PRs.

#Managing your plan

Reviews are included in your plan. You can monitor activity per PR in your workspace dashboard, and uninstall CodeReviewr from repos you don't want reviewed.

#Next steps

Create a test PR and watch CodeReviewr work. Review a few PRs, check your usage dashboard, then adjust your workflow as needed.

If something doesn't work, check our troubleshooting guide or contact us through the website.

#Alternative: CLI reviews

Prefer reviewing code locally before pushing? Use the CodeReviewr CLI to get the same AI-powered reviews in your terminal.

npm install -g @codereviewr/cli
codereviewr auth login cr_your_token
codereviewr review

The CLI is useful for:

  • Pre-commit or pre-push reviews
  • CI/CD pipeline integration
  • Reviewing changes before creating a PR

See the CLI documentation for full setup and usage instructions.
