AI-Powered Code Reviews for GitLab, GitHub & Azure DevOps

Its biggest differentiator is the zero-configuration setup. Unlike many competitors, ThinkReview works instantly as a browser extension without needing complex CI/CD integration, setup tokens, or granting access to your entire GitLab group. It enhances the developer's existing workflow directly in the browser.

ThinkReview requires host permissions to inject the review UI and fetch code diffs only when you explicitly request a review. These permissions allow the extension to add the "AI Review" button to merge request and pull request pages. Code is only read, never modified. The extension never scans repositories automatically. Learn more about permissions.

ThinkReview ONLY reads code diffs from PRs/MRs you explicitly open. It never writes, modifies, or changes any code. All access is read-only and user-initiated—code is only fetched when you click "Review Code". The extension never creates comments, commits, or modifies anything on your repositories. Learn more about read-only access.

No. ThinkReview has a zero code retention policy. Code diffs are sent to AI services for analysis and immediately discarded. Code only exists in memory for the few seconds needed to generate the review. No code is stored, cached, or retained on servers. Learn more about zero code retention.

Yes! ThinkReview is open source and available on GitHub. You can review the code to verify all privacy and security claims, including how permissions are used, what data is accessed, and confirmation of zero code retention. View on GitHub or read our Privacy FAQs.

Yes! ThinkReview works seamlessly with both gitlab.com and self-hosted GitLab instances. You can configure your custom GitLab domain in the extension settings, and it will work just as smoothly as with gitlab.com.

ThinkReview is powered by frontier models, some of the most advanced AI models available. While AI reviews are highly accurate and catch many issues, we recommend using them as a complement to human code reviews, not a replacement. The AI excels at identifying potential bugs, security vulnerabilities, code smells, and best practice violations.

Yes! ThinkReview now supports 13 languages including English, Spanish, French, German, Chinese, Japanese, Portuguese, Russian, Arabic, Hindi, Polish, Czech, and Hungarian. You can select your preferred language from the dropdown in the review panel, and all reviews and conversations will be in that language.

Yes! ThinkReview works with both public and private repositories. You just need to be logged into your platform (GitLab, GitHub, or Azure DevOps) and have access to the merge request or pull request you want to review. The extension fetches the code changes through your authenticated session.

The Free plan includes all core features with usage limits perfect for getting started. The Pro plan removes all limits, giving you unlimited code reviews, unlimited copilot conversations, advanced AI analysis, and priority support. Both plans include the same great features like AI reviews, security analysis, smart questions, and MR comment generation.

When you reach your free tier limits, you'll see a notification. You can either wait until your daily quota resets or upgrade to the Pro plan for unlimited reviews and copilot conversations. You won't lose any of your previous reviews or data.

Absolutely! You can cancel your Pro subscription at any time with no penalties. You'll continue to have Pro access until the end of your billing period, after which you'll automatically return to the free tier with all your data intact.

Your code security is our top priority. Code diffs are sent securely over HTTPS to our backend, which processes them using frontier model APIs. We have a zero code retention policy—code is only used for generating the review and immediately discarded. Code only exists in memory for the few seconds needed to generate the review. All communications are encrypted, and we follow industry-standard security practices. Learn more about zero code retention or read our Privacy FAQs.
