Everything you need to prototype a public service.
Prompt to Page covers the loop service teams actually run: pick a design system, write a brief, generate a page, run the checks, export it. Generation happens on your machine. The research, content and accessibility judgement stay with you — see what it doesn't do.
Plain-English prompts
Describe a page or a journey in a sentence — no boilerplate, no markup knowledge required.
Live design-system preview
See generation progress, then the finished page renders in the style of your chosen design system.
Accessibility checks
axe-core runs on every output using its WCAG 2.2 AA rule set. Issues are listed by severity, alongside the items axe can't decide and you need to check by hand. Defect detection, not a conformance assessment.
Automated — manual testing still neededDesign-system validation
Flags non-standard class names and structures, and repairs some common model mistakes, so prototypes stay on the chosen design system. It checks the markup, not whether the component was the right choice.
GOV.UK · NHS.UK · USWDS · NSW · Bootstrap Italia · Scottish Government · Digital Agency (Japan) · MOJ · AbstractEdit what exists, add what is missing
Point at one section and describe the change — only that section regenerates and the rest of the page is protected. Add section creates what's missing at a chosen point without rewriting anything, and a whole-page regeneration always asks first.

GOV.UK, NHS.UK, the U.S. Web Design System (USWDS), the NSW Design System, Bootstrap Italia, the Scottish Government Design System and the Digital Agency Design System (Japan) as full packs, an optional MOJ overlay layered on top of GOV.UK, and a neutral, unbranded Abstract system for everything else. Pick per project or per page.

Export & share
Download a testable ZIP with local font-stripped assets, a GOV.UK Prototype Kit project, or an assessment evidence pack; copy HTML for any design system, or Nunjucks for the GOV.UK and NHS prototype kits. Kit and Nunjucks hand-offs use the receiving project's dependencies; restricted fonts and protected marks are not bundled.

Serve a prototype on your local network — colleagues on the same Wi-Fi can open it on their phone.
Local network + QRCheckpoints & version history
Pin a checkpoint of the whole project as you iterate (from the header chip or ⌘/Ctrl+S) and restore it from the same menu. Every page also keeps its own version history, so you can restore an earlier generation of one page — or undo a single refinement — without touching the rest.
Light & dark
Full dark mode that respects your system preference. Always-visible focus rings.
Your choice of runtime
Use the built-in runtime, or bring your own with Ollama or LM Studio.
Start from a pattern, not a blank page.
Six journey templates cover the shapes most government services take. Pick one, describe your service, and the model fills in the pages.
