AI Prototyping for Product Managers
Ship real features without waiting for sprints.
Use AI to spin up interactive prototypes with your actual codebase components.
What is AI prototyping?
AI prototyping is a faster, smarter way to test ideas before you commit developer time.
With generative AI, you can turn a prompt into a working prototype without writing a single line of code.
Why is AI prototyping great for product managers?
Hand-offs, backlogs, and reviews mean that by the time your product is ready to test, the opportunity may have passed.
AI prototyping lets you spin up variations, run user tests, and validate real, clickable demos in a single day.
Where AI prototyping tools fail product managers
AI prototyping tools, like Bolt, Replit, Lovable, and v0 are great for demos, but you often end up with a prototype you can’t actually build on.
They generate pretty UIs, but they don’t connect to your custom codebase, match your design system, or scale to real users.
Production-grade AI prototyping with Fusion
Fusion changes the narrative, letting you prototype with real components from your real codebase, so that your demos don’t just prove ideas. Instead, they become the foundation of your shipped product, matching your existing design system perfectly.
Connect your team’s product
Connect your team’s product
Connect an existing repository to bring in your team’s real components and design tokens, or prompt a new project from scratch.
Prompt a new feature
Prompt a new feature
Prompt a change, such as adding a new testimonials section that pulls in live data, and watch Fusion automatically generate production-grade code.
Each change happens on a feature branch, so you’re free to experiment.
Tweak UX to your heart’s content
Tweak UX to your heart’s content
Fusion allows for granular adjustments, so you can iterate until the user experience is just as you’ve imagined.
Refine layouts, adjust component structure, or experiment with new variations without leaving the browser.
Ship to production faster

Whether you’re validating a new feature or preparing for launch, your prototype is already responsive, accessible, and built with the same components your engineering team uses in production.
Build before you backlog
Your idea -> running app. Instantly.

You can create anything from simple landing pages to full product flows, complete with navigation, forms, conditional logic, and data integrations.
Because Fusion uses real components from your codebase, every prototype is already aligned with your team’s design system and ready for production.
AI prototyping gives product managers a faster way to explore ideas, validate features, and share testable demos without waiting on a development cycle. You can prompt new interfaces, generate variations, and run user tests in hours, all inside a real codebase—all without coding.
Designers and engineers still work alongside you: designs stay aligned with your system, and any validated prototype can be extended in code without starting from scratch.
Fusion integrates with your GitHub repo, automatically detecting your components, design tokens, and code patterns.
Instead of generating throwaway HTML, it builds prototypes from the same components your engineers use, like Button, Card, or Layout.
Each change is committed to a feature branch with full Git history, so developers can review diffs, extend functionality, and merge production-ready code without starting over.
Most product managers create their first AI prototype in around 30 minutes. A typical workflow is to describe your feature (5 minutes), review and adjust the generated UI (15-20 minutes), test interactions (5 minutes), and share with stakeholders. Complex prototypes with multiple screens or data integrations might take 1-2 hours instead of 1-2 sprints.
Yes. Every prototype you create in Fusion is a fully functional web application, with real navigation, working forms, and optional API or database connections. You can share it via URL and run user tests that feel like a live product.
Because prototypes are built on production-ready components, the feedback you collect translates directly into product decisions.
