We are excited to announce Plan Mode, a new way to collaborate with Replit Agent. This mode provides a dedicated space for ideation, task outlining, and strategic discussions—all without initiating any changes to your codebase.
The default mode is now referred to as Build mode.
Key benefits
Plan Mode allows you to:
- Brainstorm ideas and explore different approaches to your project
- Plan development work with structured task lists
- Collaborate with AI on project architecture and feature planning
- Get strategic guidance and ask questions without modifying your project’s code or data
- Transition seamlessly to Build mode when you’re ready to implement
Built with safety in mind
While in Plan Mode:
- Agent is prohibited from making any code changes
- Agent can still inspect your repository, search documentation, and answer context-aware questions
- Queueing is disabled, but dynamic intelligence remains active, ensuring that users can maintain access to higher powered or longer thinking models
- While Agent won't start building in Plan Mode, it will propose a plan for a new feature when relevant. You can press "Start Building" on a plan to kick off a build
Note: You’ll need to pause the Agent to plan, just like you pause it to send another Agent message. This setup offers the full analytical capabilities of Agent, without the risk of unintended edits.
Use Cases
Feature planning
Ideal for adding new functionality:
- Break down complex features into implementable tasks
- Plan database changes and API modifications
- Design user interface and user experience flows
- Consider edge cases and error handling
Learning and exploration
Excellent for educational purposes:
- Understand different approaches to solving problems
- Learn about new technologies and frameworks
- Explore design patterns and best practices
- Get guidance on development methodologies
Planning specific features
You can also utilize plan mode and visual selector together to plan new features, updates, or ask questions about best practices:
Enabling a smarter development workflow
The new Plan Mode feature is an additional feature, and complements the existing Build Mode and Edit Mode.
Plan Mode is valuable throughout the entire app development process. In the early stages, it helps you scope new features, debug complex issues, or navigate unfamiliar code. Later on, it’s just as useful for asking questions, exploring ideas, and planning your next steps—all in a safe, focused environment designed for clear thinking.
It’s a more intentional and intelligent way to begin your development journey—on your terms.
