An AI mockup generator for mockups you can click.
Start from a sentence or a rough sketch. Agents build the mockup as a real screen on a shared canvas, so your team can click it, compare it and change it together.
Updated · By Thijs Verreck
An AI mockup generator turns a description or a rough sketch into a full-detail version of a screen, with real layout, real copy and real components. A mockup sits between a wireframe and a prototype. With an agent doing the building, you can skip the static step and get a mockup that already works when you click it.
Prototyper is an AI prototyping tool for anything visual: your agents build running apps, wireframes and slide decks on a shared canvas with your team, from real design rules, not AI slop. For mockups, that means you can start in grey boxes and end with a screen that runs, on the same canvas.

Paste one of these into the composer as written. The more real the copy in your prompt, the more the mockup tells you.
Turn the checkout wireframe I selected into a full mockup with real copy. Keep the order summary in view while the cart scrolls.
Mock up a landing page hero for a budgeting app: headline, two buttons and a product shot. Three takes: calm, playful and bold.
Create a mobile mockup of a habit tracker's today view, 390px wide: a streak count, a checklist and a bottom tab bar.
Wireframe a settings page with account, billing and team sections, then turn the one I pick into a full mockup.
How to make a mockup with AI
- 01
Start rough.
Describe the screen, or ask for wireframes first. Prototyper's wireframe skill gives you at least three options in a hand-drawn style, so nobody argues about colours yet.
- 02
Pick a direction.
Select the wireframe you like and send it to the agent, with a sticky note for anything it should keep.
- 03
Get the full mockup.
The agent builds the screen in React with real copy, in a window next to the wireframe it came from.
- 04
Click through it.
Because the mockup runs, you can try it the way a user would and catch what a static picture hides.
Wireframe, mockup, prototype
The three words name three levels of detail. A wireframe settles structure in grey boxes. A mockup adds the real look: type, colour, copy and components. A prototype adds behaviour. Our guide to wireframes, mockups and prototypes covers when each one earns its keep.
When an agent builds the screen, the mockup and the prototype stop being separate jobs: the full-detail screen already runs. You still want the rough stage when the structure is open, and the AI wireframe generator page covers that starting point.

We compare Prototyper with v0, Lovable, Bolt and Figma Make on separate pages, each with its sources and the date we last checked them.
The short version
From boxes to a real screen
Start with wireframes and turn the one you pick into a full mockup.
Mockups you can click
The mockup is a React screen, so you can try it the way a user would.
Your team on one canvas
The wireframes, the mockup and the notes all stay side by side.
Frequently asked questions
- What is an AI mockup generator?
- A tool that turns a description or a rough sketch into a full-detail screen with AI: real layout, real copy and real components, rather than grey boxes.
- What is the difference between a wireframe, a mockup and a prototype?
- A wireframe settles structure in grey boxes, a mockup adds the real look, and a prototype adds behaviour. In Prototyper the mockup is built as running code, so it is also clickable.
- Can I start from a sketch or a wireframe?
- Yes. Draw rough boxes on the canvas or ask for wireframes first, then select the one you want and ask the agent to turn it into a full mockup.
- Can I use my own AI agent?
- Yes. Claude Code, Codex, Cursor and other agents that speak MCP can connect to a workspace and build on the canvas, on the subscription you already have.
- How does this compare with Figma?
- We keep sourced, dated comparisons with Figma and Figma Make. The short answer is that Prototyper builds mockups as running screens on a shared canvas, with your agent doing the building and your team steering it.
