Plans and Questions

Ask the chat to plan, analyze or explain, and it answers without changing your app. Ask for a change and it builds it. There is no mode to switch.

No Separate Mode

GenMB used to have a Plan Mode toggle. It is gone: the chat now works out what you want from what you type. Ask a question and you get an answer. Ask for a change and GenMB makes it.

  • Questions, plans, explanations and audits never change your app.
  • A reply that changes nothing is free.
  • Requests for a change are built and checked automatically.
  • Works in the chat panel for any existing app, on every plan.

How to Ask

Just say what you want in plain words. There is nothing to click first.

1

Open the chat panel

Navigate to your app and open the chat panel.
2

Ask for a plan

For example: "Plan how you would add Google sign-in and a profile page. Don't change anything yet."
3

Review the answer

The AI replies with a plan and leaves your app as it is.
4

Build it or adjust it

Reply "go ahead and build this", or ask for changes to the plan first.

Pro Tip

Asking for a plan first helps with big features that touch many parts of your app. You see the scope before anything changes, which means fewer fix-and-break cycles.

What You Get

A plan usually covers:

Understanding

What the AI understood from your request, so you can check it before any work begins.

What changes

Which parts of your app would be added, changed or removed.

Steps

How the change would be made, specific enough to review.

Things to consider

Trade-offs, edge cases and other ways to do it.

Architecture Planning

For complex multi-page apps, GenMB automatically creates an architecture plan before generating code. This happens behind the scenes, so there is nothing to switch on.

  • Triggered automatically when the AI detects a complex, multi-page application.
  • Designs the page structure, data model, and shared components before generation starts.
  • Ensures all generated files are architecturally consistent: pages share the same data model, navigation, and component patterns.
  • The architecture context is injected into the generation prompt so every file aligns with the overall design.

Automatic

Architecture planning runs automatically for complex apps. You do not need to enable it: the AI decides when an app is complex enough to benefit from upfront architecture design.

GenMB Code Planning

GenMB Code (Pro feature) adds execution plans with approve/reject gates. Before modifying any files, the AI creates a detailed plan listing every file action (read, create, edit, delete) and waits for your approval.

Read

AI will read the file to understand current implementation.

Create

AI will create a new file at the specified path.

Edit

AI will modify an existing file with targeted changes.

Delete

AI will remove a file that is no longer needed.

You can approve the plan to proceed, or reject it with feedback. If rejected, the AI re-plans based on your feedback without making any changes.

GenMB Code planning is especially useful for large refactors where you want to review the scope of changes before they happen. The approve/reject gate ensures nothing unexpected is modified.

Good Things to Ask

Asking first is most useful when getting it wrong would cost you time.

Big features

"Plan how you would add payments and a checkout page."

Choosing an approach

"What are the options for storing user uploads, and which do you recommend?"

Understanding your app

"Explain how the booking page works."

Finding a bug

"Why does the form clear when I press save? Don't fix it yet."

FAQs

Where did Plan Mode go?▾
There is no separate Plan Mode any more, and no toggle to find. Just ask in chat. If you ask for a plan, an explanation, an audit, or any question, the AI answers without changing your app. If you ask for a change, it builds it.
Does asking for a plan use my credits?▾
No. A reply that changes nothing in your app, such as a question, a plan, an explanation or an audit, is free. Chat edits that do change your app cost 1 to 40 credits, based on how much work they take.
How do I build the plan once I like it?▾
Reply in chat with something like "go ahead and build this". The AI then makes the change, using the plan from the conversation.
Is this available on the Free plan?▾
Yes. Asking for plans and explanations in chat works on every plan. GenMB Code planning with approve/reject gates requires a Pro subscription.
