How it works
- Paste code or a diff: Drop in a snippet or a unified diff straight from your pull request.
- Select the language: Choose from JavaScript, TypeScript, Python, PHP, Java, Go, Rust, C#, Ruby, or SQL.
- Get the verdict: The instrument returns an overall verdict plus bugs ranked by severity, edge cases you missed, and corrected snippets.
Good to know
- Treat the review as a tireless junior reviewer, not a replacement for human judgment on architecture and product decisions.
- Do not paste proprietary code you are not authorized to share with an external AI service.
