Real-Time vs After-the-Fact Review

We review code while your AI writes it, saving hours of upstream debugging pain. CodeRabbit only reviews after PR creation when context is lost.

Real-Time Intent

Because we operate as code is being generated, we have full access to your original intent and can review the AI-generated code with that context in mind.

Thank you for spotting that — you're right. Let me implement the remediation plan you suggested.

Real-Time Alignment

Enforces rules that are manually defined by your team or automatically learned from your codebase and team interactions with AI. We get better over time as we do more reviews.

Real-Time Verification

We review while your AI writes, catching issues instantly as code is generated. CodeRabbit reviews after code is written and requires human action to apply fixes, slowing down your development flow and creating frustration.
