Prototype inside your real codebase and ship a PR
Plan with the AI, build on a branch of your actual product, preview in context, then turn the validated prototype into a pull request.
5 steps
- Plan mode: describe the feature, paste Figma or PRD context, answer clarifying questions
- Approve the plan and switch to build mode
- Preview the change on a branch of your real product
- Use it in sprint planning and user validation
- Create a PR for engineering review
