Plan Mode was introduced by Cursor in October 2025. Plan Mode assists AI Agents in executing Complex Projects and long-term tasks by providing clear Context and Direction right from the start. In other words, Plan mode sets up a plan before execution in Cursor AI.
1. What Plan Mode does?
- Does not execute immediately - AI will NOT automatically edit files, run commands, or change your system
- Plan Mode does deep research into your codebase
- Plan Mode asks you for clarification on requirements (to avoid misunderstandings).
- Plan Mode Creates a detailed plan (It lets you review/edit the plan like a design document.)
- Only then does it generate the code.
2. How to use Plan Mode
- Start planning by pressing Shift + Tab in the agent input.
- Answer clarifying questions on your requirements for the best output quality.
- Review or edit the detailed plan, then build directly from your plan when ready.
- Optionally, save the plan as a Markdown file in your repository for future reference.
3. Example in my demo project
I have a plan to change language from English to Vietnamese in my demo project.
Start planning by pressing Shift + Tab in the agent input.

As you can see, Plan Mode will be very useful when you have the following needs:
- For complex, multi-step tasks
- When there are Major changes in the codebase:
- When you want to preview what the Cursor AI (Agent) will do before execution
- When you need to ensure the Cursor AI (Agent) correctly understands the requirements.
