Looking for an AI-powered code review assistant

Spending too much time on manual code reviews. Our team reviews take 2-3 hours per PR, and we often miss common issues like performance problems, security vulnerabilities, or style inconsistencies. Junior developers especially need more guidance, but senior devs don't have time to review everything thoroughly.

An AI assistant that integrates with GitHub/GitLab and provides intelligent code review comments and suggestions. Should catch common issues, suggest improvements, and help maintain code quality standards automatically.

GitHub integration, support for multiple languages (JS, Python, Go), customizable rules, privacy-focused (code stays secure), learning from team patterns
