An open-source iPhone app that builds live web apps and native iOS apps from a prompt. The agent writes the code, ships it to the cloud, and you preview it — or install it on your phone — without leaving the app.
No project setup, no boilerplate, no deploy dance. You describe it, the agent builds it in the cloud, and it streams back into your hand — live and editable.
Type or speak a prompt in the composer. Flip the Web / Mobile toggle to pick what gets built. Voice is transcribed by Whisper, server-side.
Claude — or an open model — writes the whole app. Web apps spin up in a Daytona sandbox; iOS apps compile on Chorus cloud Xcode, with compile errors auto-repaired.
Web apps render in-app; iOS apps stream from a cloud iPhone simulator. Ask for "the download link" and the agent signs it and drops an OTA install link in chat.
Claude stays the default — and the right call for SwiftUI. Open-weight models route through the Vercel AI Gateway and shine on web builds. One key, your choice per project.
Anthropic API. Best for native iOS, where Swift quality saves repair cycles.
Open-weight models, pay-per-token. Strongest on the web-build path.
Web prompts become polished static apps in a public Daytona sandbox. Mobile prompts become real SwiftUI apps compiled in the cloud — same composer, one switch.
Build status streams in real time over Convex. Follow-ups edit the app.
Compile errors on mobile builds are fed back to the agent and fixed — automatically.
Ask for the download link; the agent ad-hoc signs the build via your Apple account on Chorus and posts an OTA install link right in the chat.
A mic in every composer, transcribed by Whisper — your key never leaves the server.
A keyless gateway proxy lets every app you build ship AI features without leaking a key.
Clone it, point your keys at it, and let Claude Code set it up end-to-end. The whole thing runs on your own accounts — none of your keys are ever committed.
