AI prototyping tools, quick review

A practical take on three tools that help PMs shorten the distance between an idea and a visual prototype.

If you are a PM trying to move from idea to prototype fast, I tested three tools that promise exactly that: Lovable, UX Pilot AI, and Google Stitch. None of them replace designers. They do help you get to something concrete earlier, which is often what unblocks alignment.

Lovable

• Turns a product concept into clean, usable screens.
• Visually polished and fast, especially for iteration.
• Best for: early alignment and stakeholder buy in.

UX Pilot

• Starts with user goals before jumping into screens.
• A logic first approach that makes flows feel thoughtful.
• Best for: teams that think in journeys first.

Stitch by Google

• Still early stage, stronger for mockups than prototypes.
• Evolves with your brief and integrates smoothly into Figma.
• Best for: teams already deep in the Google ecosystem.

The takeaway

These tools do not replace designers, but they empower PMs to shorten the distance between ideas and visuals. That can make decisions faster, feedback sharper, and collaboration easier.
