Review-requested PRs are automatically loaded. Click any card to start a workspace-isolated review.
When re-running a review, you can customize the analysis depth:
- 🧠 Context-Aware Review: Uses Tree-sitter to find callers and implementations of modified code in the project.
- 🎯 Change Intent Analysis: Determines why code was changed (File-level or Block-level).
- 📊 Code Visualization: Generates Mermaid Flowcharts or Sequence Diagrams or Class Diagrams for modified functions.
- 🔍 Impact Analysis: Assesses broader impact (Module, Project, or Dependencies).
- ✨ Semantic Diff: Detects moved code, refactoring patterns, and ignores whitespace/comments.
- 💬 Custom Prompt: Add your own specific instructions for the AI reviewer.
- Auto-Review: The AI analyzes the PR on load. Click "Re-run" to trigger a fresh analysis with custom options.
- Ask Assistant: Highlight any code in the specialized "Diff Editor" or "File Tree" and ask questions in the side panel.
- Go to Definition: Right-click on symbols (even in Ruby/Java) to jump to their definition.
- Find Usages: See where functions or classes are used across the PR.
