Prompt to app
One description becomes one complete app: markup, styles and behaviour in a single HTML document, generated with a frontier language model.
GroundDeck · AI app builder
Type what you want in plain language. GroundDeck turns it into a real, versioned web app you can preview instantly, share with a link and export as a single file. No boilerplate, no setup, no ticket queue.
What comes out
Every generation returns a single HTML document with its styles, behaviour and state inline, streamed into a sandboxed preview as it is written. Keep it as a version, refine it in conversation, publish it under a link, or take the file with you.
How it works
GroundDeck is a conversation, not a form. You describe, it builds, you refine. Every step leaves a version you can go back to.
01 · DescribeName the audience, the job the app should do, the main screens, and what it should remember. A sentence or a paragraph, your call.
> a habit tracker for remote teams, weekly streaks, shared board
02 · PreviewThe app streams into a sandboxed live preview while it is generated. Ask for changes the way you would ask a colleague. Each answer becomes a new, immutable version you can diff and restore.
03 · LaunchPublish a link that pins one version and counts its views, or export a standalone HTML file that runs anywhere. Your app, not a lock-in.
What ships today
Everything below exists in the product now. Nothing on this page describes a roadmap item as if it were shipped.
One description becomes one complete app: markup, styles and behaviour in a single HTML document, generated with a frontier language model.
Generated code runs in an isolated frame with an opaque origin. It can render and react, but it cannot reach your session or anyone else’s data.
Every generation and every refinement is a new version. Diff any two, restore an older one, and the history stays intact.
A share link pins a specific version, serves it from its own origin, and records views so you know whether anyone looked.
Published apps get a small server-side data API for key-value state and form submissions, so a waitlist or tracker actually keeps its entries.
Download the app as one file with the runtime and badge stripped out. Host it on any static server, or just open it.
Who it is for
GroundDeck is not trying to replace your production stack. It gets you to a thing you can click, show and argue about in minutes.
Turn a pitch into a clickable product shape. Put a real prototype in front of ten people this week instead of a slide deck.
Trackers, calculators, approval flows, small CRMs. The tools nobody has time to build, described in the time it takes to write the ticket.
Sketch dashboards, operator consoles and agent workspaces as working screens before the backend exists, then hand over something concrete.
Built carefully
An app builder that runs other people's generated code has to be paranoid. GroundDeck is. These are engineering decisions, not marketing promises.
Questions
If yours is missing, write to us.
One complete web app per generation: a single HTML document with its styles and behaviour inline, kept as a version in your project. You can preview it, refine it, publish it under a share link, or export the file.
No. You describe what you want in plain language. If you can write a decent brief for a colleague, you can write a good prompt for GroundDeck. Knowing how to code helps you ask for sharper changes, but it is not required.
Yes. Published apps get a small server-side data API for key-value state and form submissions, so a waitlist keeps its sign-ups and a tracker keeps its entries. You can view and erase that data from your project.
There is an offline template mode that builds deterministic apps for common shapes like trackers, dashboards and landing pages. It exists so the product keeps working when generation is paused, not as the main event.
Private preview. It is built and operated by one person in Germany, and access is opened in small batches so every builder can get a real answer when something breaks. Ask for a seat and say what you want to build.
