Design your next big idea

Say the idea. See the app.

Chat about what you want to build. SnapUI designs the screens, lets you tap through them, changes anything you ask in plain words, and hands a full build spec to your coding agent.

How it works

From a chat to a build
spec, in five steps.

No design tools to learn and no code to write. You talk, SnapUI designs, you decide what stays.

  1. Brainstorm

    Chat it through. SnapUI asks what a designer would: who it’s for, the feel, the must-haves.

  2. Blueprint

    A name, colours, a font, and every page the app needs.

  3. Screens

    Real, tappable screens you preview on your own phone, bottom bar and all.

  4. Revise

    Say what to change. Keep it or undo it. Every version is kept.

  5. Share & export

    A link anyone can open, store images, or a build spec for your coding agent.

Demo

Watch it get designed.

A guided demo. Every screen here was designed by SnapUI ahead of time; in the app, it designs yours from your own words.

BBrainstorm

How a brainstorm goes.

An example conversation for Artemis Studios Pool and Garden. SnapUI asks what a designer would; here, you just tap an answer.

Brainstorm

A guest app for a small hotel

  • Guest app
  • New chat
Example conversation

A guest app for our pool and garden studios on Naxos. Guests should see their stay, ask for towels or a repair, message us, and find good places nearby.

SnapUI: Lovely. Should guests sign in first, or look around as visitors before they arrive?

Visitors too. Let people look around before they book.

SnapUI: Got it: visitors see the weather, the studios and the local guide; signing in unlocks their stay, requests and chat. I’ll design 5 screens, starting with the home dashboard.

CRevise

Change anything in plain words.

A real edit to the Write screen of MindArchive. Edits run in the background; you review each one, keep it or undo it, and every version stays in the page’s history.

DScreens that think

AI that works inside
your prototype.

MindArchive has AI built into its screens, and it really works when you preview it in the SnapUI app. Pick a feature to see where it lives and what it does.

Pick a feature

In the appRewrites a note for clarity and style while keeping your voice and meaning. Nothing changes until you accept it, and saving can suggest philosophers who speak to the note.

Voice works in the app

Export

Hand it to a
coding agent.

When the screens feel right, export a build spec your coding agent can follow from the first phase to the last, or take the screens just as they are.
