The AI remembers how your app works

Everything about the app is on its computer: the code, the files you've sent and every past chat. Months later, you don't have to explain the app again.

Upload photos, spreadsheets and documents in the chat

Send a new price list, and the AI updates the prices on your site.

Fork a chat to try another idea

A fork starts from everything the first chat knew, and the first stays as it was.

Choose the AI each app runs on

Use the AI your plan includes, or your own OpenAI or Anthropic key with no fee from us. Each app runs Codex or Claude Code.

Every change is backed up within an hour

Backups are kept off-site for 7 days. You can also download the whole app as a .zip or save it to your GitHub.

One app costs $15 a month

That includes 30 hours of computer time. Start from a Starter App, a GitHub repo, a .zip or a blank app.
