“We stopped presenting one direction and defending it. Now the client opens the link, votes, and we start building the same day. Sign-off went from three weeks to one call.”

01 — How it works
From rough idea to a direction worth building — in 3 minutes.
01
Describe what you’re building
Describe the website or app you want — a product idea, a landing-page brief, a feature request, or just a visual direction.
02
Generate multiple directions
Choose 1–10 directions. A different AI model builds each one, in parallel, side-by-side on your canvas.
03
Refine what works
Select the strongest direction, refine it by prompt, comment, or direct edit, then export the code.
02 — Multi-model generation
See possibilities. Not just one possibility.
Every model reads a brief differently, so MultiPrototype puts Claude, ChatGPT, Gemini, Grok and more on the same brief — compare their designs side by side and combine what works.

03 — Refinement
Refine the winner until it’s perfect.
Change the layout, rewrite content, adjust the visual system, add a section, or redesign a flow using a simple prompt.
04 — Share & vote
Share with your team. Have a vote.
Send your team or client one live link — no account needed to open it. They browse every direction and vote for a favourite. Blind mode hides which model made what, so people judge the design and not the name.

05 — Code export
Real code, not a mockup you can’t ship.
Every direction is real, working HTML and CSS you can click through. Refine it by chat, comment, or direct edit, then export clean code and finish it in Claude Code, Codex, Lovable, or your own repo.
06 — Who it’s for
Built for people who decide from real options.
Freelancers & agencies
Pitch more than one idea
Show a client several finished directions from one brief, let them pick, and charge for the choice instead of the revision rounds.
Founders

Product & design teams
Replace the debate with artifacts

Engineers
Skip the boilerplate
Generate working starting points, export clean HTML, CSS and JS, and finish it your way.
07 — Reviews
Builders who stopped guessing.
★★★★★ 4.7/5
“Six finished concepts in the time it used to take me to build one. I still can’t quite believe it.”
Marcus
Builder
“Seeing every model’s take on the same brief taught me more about layout than a year of scrolling inspiration sites.”
@pixelsara
Designer
“Design review used to be me, one mockup, and a room full of opinions. Now we put four real options on screen and the conversation is about which one, not whether.”
Jonah
Design lead
“The directions really are different from each other, which is the whole point for me. I pick a favourite, adjust the brief, run a fresh set.”
LF
Lena Fischer
Product manager
“Blind mode was the surprise. Half the team was convinced they preferred one particular model, then voted for something else entirely once the names were hidden.”
TR
Tomás Rivera
Head of product
“I use it as a starting point, not a finished site. Two runs, take the layout I like, rebuild the rest properly.”
PR
Priya Raghavan
Frontend engineer
“I pitch three directions for what one used to cost me in hours. Clients decide faster and my revision rounds have basically halved.”
