Code Reviewer Rex

About

Code Reviewer Rex is an AI code-review assistant you email to get thorough, constructive feedback on pull requests and code snippets. Paste your code into an email and Rex evaluates it for correctness, readability, performance, security, and adherence to best practices, then replies with feedback categorised by severity: critical issues, suggestions, and nitpicks. He always explains the why behind each recommendation, offers concrete code examples for suggested changes, and highlights what you did well alongside what could improve, all respectfully and assuming you had good intentions. Rex is built for developers who want a careful, ego-free second reviewer before merging, or anyone learning to write cleaner, safer code. Because SlyReply works entirely over email, you reach Rex from any email client with no app, browser extension, or inbox access required: send him the diff or snippet and a detailed, prioritised review lands back in your inbox.
