Build an app
Describe an app and the chat builds it: pages, sign-in, saved data, server code and AI. Try it in the preview, then publish it at its own address.
Press Build an app under the message box on the home and describe what you want, for example "a budget tracker where people sign in and add income and expenses, with a chart by category". The first time, Before you build an app asks you to read the App Builder Terms and press Agree and continue. A build takes a few minutes and ends in an app card in the chat.
Apps can have several pages, sign-in for their own users, saved data, scheduled jobs, emails to you or the app's users, and AI features. To change something, say so in the same chat ("add a dark mode", "the total is wrong") and the chat makes the next version. Your apps, under the examples when Build an app is chosen, lists the apps you made; each opens the chat it was built in.
The app card
Apps with scheduled jobs list them under Scheduled jobs, with Run now; they run on their own once the app is published. Download ZIP gives you the code as a standard Vite project.
Publishing
Press Publish and the app goes live at its own address ending in .prompteryx.app, which anyone can open. After a change, Publish update keeps the same address; Unpublish takes it offline. Every live app shows a small Built with Prompteryx · Report link.
- Before it goes live, Publish checks the app. It refuses secret keys written into the app's code (move them into Secrets), adult content, and pages that imitate a well-known sign-in page.
- On the trial you can build and preview as much as you like; putting an app online is included from the Starter plan.
What each plan includes
Enterprise has higher limits: talk to us. Anyone can have at most 10 live apps. Publishes beyond your plan's monthly allowance cost $0.05 each, from your AI credits. Building an app is paid with AI credits like any chat reply (see This reply: N credits under it), and AI features inside a published app are paid from your credits too, with a monthly cap per app.
In the app card, below Publish, open Custom domains, type the address (for example shop.example.com) and press Connect domain.
Add the records it shows at the company where you bought the domain, then press Check. It moves from Waiting for DNS to Issuing certificate to Live. A domain connected before you publish shows your app once you do.
Connect GitHub, then Export to GitHub puts the app's code in a repository of yours, on any plan. Download ZIP works on any plan too.
On Pro, GitHub sync keeps them together: changes pushed to GitHub can be brought back into the app.
The model that builds apps is the Build an app row in Settings → Model defaults (see Models and Auto). For a simple site without sign-in or saved data, Build a website is quicker (see What you can make).
