ThinkReview: Agentic code reviews in your PR sidebar

ThinkReview adds full-context AI code review to your GitHub, GitLab, Azure DevOps, and Bitbucket PR/MR sidebar. Get summaries, bug and security checks, missing test suggestions, chat, and custom review agents without CI setup, webhooks, bot accounts, or automatic comment spam. The reviewer stays in control of what gets posted. Supports cloud models, OpenRouter, and local Ollama.

Hey Product Hunt! 👋 I'm Jay Elsheikh, the creator of ThinkReview AI Copilot. Like many of you, my days are spent in GitLab. And while I love it, I grew frustrated with the constant friction in the code review process. Waiting for feedback on a merge request kills momentum, and the existing AI tools I tried felt clunky—they either forced me out of the GitLab UI or required a complicated setup with CI pipelines and API tokens. I wanted a tool that felt like a natural extension of GitLab itself. What if you could get a powerful AI-powered second opinion on your code, instantly, without any setup? That's why I built ThinkReview. It's a simple Chrome extension that automatically detects when you're on a merge request page and provides an instant code review. The goal was to remove every possible barrier to entry. Here's what makes it different: ✅ Truly Zero-Setup: This is the core principle. No sign-ups, no OAuth, no generating personal API tokens, no backend configuration. You just install it, and it works. 🧠 Powered by Gemini 2.5 Pro: I chose Gemini because it's fantastic at understanding code context. It doesn't just find unused variables; it explains why code might be inefficient, spots potential bugs, and offers meaningful suggestions on logic and readability. 🌐 Works Everywhere: Whether you're on the public gitlab.com or a private, self-hosted GitLab instance, ThinkReview integrates seamlessly. 💸 Completely Free: No trials, no paywalls, no hidden costs. It's a tool built for developers, by a developer. I'd be thrilled for you to try it out on your next merge request. It takes 30 seconds to get started, and I genuinely believe it can bring a little more flow back into your workday. I'll be here all day to answer any questions. What's the biggest bottleneck in your current code review process?

Thanks for building ThinkReview — I’ve been testing it on GitLab MRs. One question: Does the extension have (or plan to have) capabilities to check for code reusability, functional flow, or possible regression issues? These are usually the main focus areas during our code reviews, and I was wondering if ThinkReview is intended to cover them or if it’s primarily aimed at surface-level best practices and quick suggestions.

Hi Srinivas, thanks for your kind review.

Currently, the Extension context only includes the patched files where changes were made. Within this scope, it can identify code reusability, logical issues, and security concerns. However, it doesn’t have access to the full source code of the project.

This is the first release of the extension so we are currently assessing how users are going to use it and features they need.
However I wanted to ask you if you tried any existing code review tools already ?

Hi Srinivas, thanks for your kind review.
