How it works

Polyxd turns the answer into a screen.

A small document says what the screen means. Your design system draws it. A verifier checks it before anyone sees it.

Apps only have the screens someone built in advance. Ask for anything else, and you get a paragraph.

Split Friday’s dinner with Priya

Sure. To split a payment, open Payments and choose New payment. If Priya is not saved yet, tap Add payee and enter her name, sort code and account number. Enter the amount you want to send, which would be half of the total if you are splitting evenly. Add a reference so she knows what it is for, then review the details and confirm with your passcode. If you would rather ask Priya to pay you, open Requests, choose New request, pick Priya from your contacts or enter her phone number, then set the amount and send. You can check the status of a request at any time from

The ask
A document, not code
Your design system draws it
Checked, then shown

Four layers. Your generator touches one.

01
The ask
Typed, spoken, or sent by someone else’s agent.
02
A document
44 components, bound to data your app supplies. UI is data, never code.
03
Your design system
The real renderer draws it with your tokens, in React, Web Components, Vue or Svelte.
04
The check
Schema, patterns, allowed actions, accessibility and an agent task, before it is shown.

Checked before anyone sees it.

Every label read aloud
Contrast 4.5:1 and up
Only allowed actions
Every value bound to your data
An agent finished the task

renders checked across the examples and four products: 4,680
tasks finished by agents, by name alone: 936 / 936
deliberately broken screens caught: 20 / 20

Gone when it’s done. Familiar when it’s back.

Open spec. Any model. Your design system.
