ProtoPie

ProtoPie lets designers build realistic, interactive prototypes without writing code. It supports dynamic interactions such as form validation, complex motion, and logic using variables and formulas, and can incorporate native device sensors, voice input, and multimodal data. The tool also offers a beta AI feature for generating interactions and flexible integration of real‑world data.

The platform is aimed at product teams and individual designers who need high‑fidelity prototypes that simulate real device behavior, including automotive UX and HMI scenarios. It works with assets imported from other design tools and provides shareable links and interaction recordings for easy collaboration and testing.

ProtoPie includes a learning hub with courses, a community forum, and a gallery of user‑created prototypes. These resources help users adopt the tool quickly and explore advanced interaction patterns across multiple devices.
