# Prototo

> Prototo is a prompt-native design environment for iPhone. Designers describe screens in plain language to Claude Code, and real native iOS layouts appear in the iOS Simulator and on a physical iPhone running the Prototo app. There is no canvas, no IDE, and no engineering concepts. Building prototypes locally is free and unlimited; paid plans cover sharing them as live, native previews in the browser.
