Brainstorm in Plan mode

Plan mode is Startbase's planning and reasoning mode, designed for moments when thinking, exploration, or clarity is more valuable than immediate execution. It can reason across multiple steps and inspect files, logs, or other relevant project context as needed.

In Plan mode, you can explore ideas, investigate issues, and reason about changes before any code is written. Startbase often asks clarifying questions to better understand your goals. When there's a clear implementation to propose, it creates a formal plan you can inspect and refine.

• Explore product or feature ideas before committing to a direction
• Ask questions about your codebase or existing behavior
• Investigate bugs or confusing behavior safely before making changes
• Compare multiple approaches and understand tradeoffs
• Design architecture or database schemas
• Understand the impact of potential changes before making them

You can use Plan mode in two ways:

• Start in Plan mode when beginning a new project or exploring an idea
• Switch to Plan mode at any point during development to pause execution and think

Activate Plan mode
Click Plan next to the message input, then describe what you want to explore or decide.

When Plan mode proposes a concrete implementation, it creates a plan: a structured set of proposed changes shown as a card in the chat. Plans persist in the conversation and can be referenced later. Review and refine the plan, then switch to Agent mode to execute it.
