ThinkReview is a browser extension for AI-assisted code reviews on GitHub, GitLab, Azure DevOps, and Bitbucket. It combines fast review summaries, security and best-practice findings, and structured code suggestions with a practical reviewer workflow: reviewers keep control, can copy/edit suggestions, and post under their own name. For teams with stricter standards, ThinkReview supports custom review agents (including security-focused checklists and references) to produce more consistent findings across platforms. It also supports cloud models and local Ollama setups for privacy-sensitive environments, and includes one-click implementation handoff to IDE agents like Cursor, Claude Code, and GitHub Copilot.

Questions & Answers

As answered by people managing ThinkReview and Code2Flow.

What makes your product unique?

ThinkReview's answer

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/GitHub project. It enhances the developer's existing workflow directly in the browser.

Why should a person choose your product over its competitors?

ThinkReview's answer

You should choose ThinkReview for its simplicity and speed. It's the fastest way to start with AI code reviews—install the extension, and you're done. It empowers individual developers to improve their reviews immediately, without the overhead and enterprise-level pricing of deeply integrated tools.

How would you describe the primary audience of your product?

ThinkReview's answer

Our primary audience consists of individual developers and small to medium-sized teams using GitLab. It's perfect for developers and team leads who want to improve code quality and efficiency without a complex, top-down implementation process.

What's the story behind your product?

ThinkReview's answer

The story is simple: it was born from the founder's frustration with code reviews being a slow, repetitive bottleneck. The goal was to create a tool that was easy to install, worked out of the box, and acted as a true AI copilot to assist the human reviewer, not just an automated bot.

Which are the primary technologies used for building your product?

ThinkReview's answer

The core of the product is a browser extension built with JavaScript, HTML, and CSS. It communicates securely with major AI and Large Language Model (LLM) APIs to provide its intelligent feedback.

Who are some of the biggest customers of your product?

ThinkReview's answer

As a recently launched tool, our primary user base consists of individual developers and growing teams who have adopted ThinkReview to streamline their personal and team workflows. We are focused on building this grassroots support before targeting large enterprise customers.
