Miro Prototypes helps product teams turn early ideas into interactive prototypes faster — moving from concept to a clear direction before design or code.
This guide shows you how successful teams think and work with AI-powered prototyping: plan with context, generate intentionally, iterate as a team, and test what matters. Once you know the basics of how Miro Prototypes work, here's how to use them like a pro:
Step 1: Think in context
The best AI prompts start from real work. Use the canvas as your foundation by selecting sticky notes, product requirement docs, user flows, screenshots, or any artifacts that capture your team’s thinking.
Start where your team left off
Select the canvas content that defines your idea. AI uses this context to shape structure and logic. You can use this prompt to get started, just adjust the content to match your specific selection.
Prompt example:
“Create a mobile prototype with five screens based on the selected PRD and opportunity map.”
Iterate on existing products
Drop in any product screenshot. Miro AI converts it into an editable mockup so you can make changes and improvements without starting from scratch.
💡 Select your screenshot and use convert image to prototype from the context menu. No prompt is needed.
Alternatively, you can use a screenshot or selected prototype as context for the next iteration in the AI chat as well.
Prompt example:
"The selected screenshot is a list of stock indexes and their price development today. Create a version of the screen with a list of similar price development of the largest crypto currencies below the current list. The rest of the current screen design should stay exactly the same as they are in this screen. Please remember to expand the footer to make room for the new list segment. Please change the text output to English in the entire screen."

- Map out the steps: Roughly sketch the journey in sticky notes or diagrams and define how many screens you'd want (e.g., Sign-up → Dashboard → Checkout).
- Set the vibe or theme: Add a reference screenshot or style guide so the AI matches your desired look and tone.
- Detailed prompts provide better results: The more detailed your prompt, the closer the generated prototype will be to what you want. You can get as granular as providing specific hex codes for the colors of different elements.
Prompt example:
"Create a mobile prototype with 5 screens based on the selected PRD and Opportunity mapping exercise. The styling and theme of the design should exactly match the style of the selected screenshot."
Step 2: Pause before you place
It's difficult to get visuals right in the first prompt so be ready to edit and iterate a few times. While you don't need a big prompt, Miro AI generates screens that are as close to your prompt as possible. It can help to be specific about structure, colors, visual hierarchy etc. if that is important to you.
Iterate in steps
The staging area is your sandbox. Keep what clicks, regenerate what doesn’t. Select any frame and use Miro AI to make changes before placing.
Prompt example:
“Simplify this layout and highlight the main action.”
Compare directions
- Flip between versions: Click through iterations to choose the best direction.
- Side by side: You can copy one version and paste it next to another to compare visually.
Go further
- Work in loops: Generate → refine → share. Don’t expect perfection on the first try.
- Add notes for context: Before placing, create a sticky to capture what you were testing or exploring.
✏️ Iterate freely with AI before bringing your ideas to the team. Click Apply to canvas when you’re ready for everyone to see and edit.
Step 3: Iterate as a team
Once your prototype is on the board, review, refine, and evolve the concept together (with AI or by hand) until you align on what’s working and why.
Walk through it together
- Connect screens to reveal logic gaps and next steps.
- Use the Prototype Format and Focus Mode to share only the prototype, without the distraction of the full board. Pin the Format to ensure it opens automatically for others when they open the board.
- Switch to Preview Mode when presenting so everyone follows the same flow, with full context just a click away.
Comment directly on screens, react with stickers, and capture what works (and what doesn’t). Annotations help ensure the whole team is in alignment.
Edit by hand when it matters
Not every change needs a new prompt. Sometimes it’s faster and clearer to just tweak it yourself. Use the Prototyping Library to swap components, adjust spacing, or rewrite text.
Anyone on the team can take control, make edits, and push the idea forward.
Go further
- Style with purpose — Include your brand colors in the prompt. Alternatively, upload a screenshot of your product for the AI to automatically apply the style. This helps make prototypes look authentic.
Prompt example:
"Use our brand guidelines: #0052CC for primary actions"
💡 Select the screens and import the style from an image in one go through the context menu. Apply image theme.
- Add Talktracks for async feedback: Record quick walkthroughs to explain your thinking and get feedback without meetings (or as pre-work before the meeting).
- Capture decisions in comments: Summarize key feedback or next steps right on the board so nothing gets lost in Slack or email threads.
Step 4: Test and refine
Run checks, gather insights, and apply learnings.
Ask your Sidekicks
Before you move to design or development, validate your concept with AI Sidekicks and quick team reviews. Bring in the UX Researcher or Content Designer Sidekick for a fast review from another perspective. Treat this as lightweight user testing.
Prompt example for the UX Researcher Sidekick:
"Analyze the selected prototype and create a report of the 5 most critical usability issues and clear recommendations for how to resolve them.
Please summarize the 5 recommendations in an executive summary at the top with one bullet for each recommendation"
Apply what you learn
Refine layouts, tighten copy, and fix friction points until the story feels effortless. Try the Design Prototype Sidekick to make iterations.
Prompt example:
"Please create a new version of the selected prototype with the key recommendations in the selected report implemented."
Use Flows to keep work connected
Use AI Flows to automate repetitive tasks, streamline processes, and improve productivity directly on the Miro canvas. Turn your team’s ideas into interactive visuals that you can test, share, and compare side by side like translation variants.
Try the Localize Prototypes template to test it yourself.
Step 5: Share and repeat
Hand off when logic is solid
Use Miro Prototypes to align on direction before designers move into design tools or developers start building (or vibe coding). This prevents costly rework and ensures everyone agrees on the solution before you invest hours in high-fidelity execution.
💡 Use the Prototype Format and Focus Mode to share only the prototype, without the distraction of the full board.
The takeaway
Prototyping isn’t about creating a pixel-perfect final design. It's about progressing toward a usable product. Miro Prototypes helps teams see ideas sooner, align faster, and build the right thing together.
The sooner your team can see an idea, the sooner you can align and build the right thing.
