Interaction prototyping for macOS and Windows with AI-generated interactions

ProtoPie is an interaction prototyping tool for macOS and Windows that lets designers build detailed prototypes and generate interactions with AI. The homepage says it can be started for free and lists industry solutions such as automotive and aviation. Paid plans are on its pricing page.

ProtoPie is built for prototypes with detailed interactions, which the vendor describes as advanced prototyping. The homepage says AI can generate interactions that the designer then refines, and that clean specifications can be handed off to developers. The site lists industry solutions for automotive, aviation and finance, which points to complex product interfaces.

Desktop downloads are listed for macOS and Windows. Compared with Figma, which covers design and prototyping in one browser tool, ProtoPie focuses on interaction detail, so it complements a design tool rather than replacing one. The free start is listed on the homepage, and paid plans are on the pricing page.
