Revieu is a Chrome extension designed to enhance the code review process on GitHub by integrating AI capabilities. This free add-on operates seamlessly within GitHub Pull Request pages, allowing users to obtain structured code reviews in real-time without needing to switch between tabs or manually copy diffs. With options to choose between two AI providers, Claude and Gemini, users can tailor their review experience to their specific needs. The extension supports various review modes and tones, ensuring that the feedback is relevant to the context of the code being analyzed.

The structured output categorizes reviews into Critical, Improvements, and Minor sections, making it easy for developers to identify areas needing attention. Revieu also accommodates large diffs by providing a file selector for focused analysis. Privacy is a key feature, as all data handling is done locally, ensuring that no sensitive information is transmitted to external servers. Overall, Revieu streamlines the code review process while prioritizing user data security.
