odeReview AI is the first VS Code extension with a completely free, built-in AI — no API key or credit card needed. Unlike Copilot or CodeRabbit, it works out of the box: select code, press Cmd+Alt+R, get instant bug detection, performance analysis, security scanning, and a quality score. One-click fixes, inline diagnostics with lightbulb actions, and support for GPT-4o and Claude 3.5.
