What platforms does ProtoPie support?

ProtoPie is available on Web App, MacOS and Windows.

What are the limitations of ProtoPie?

Steep learning curve for anyone without a grasp of triggers, variables, and conditional logic. No pricing tiers, plan limits, or trial length appear on the homepage, so budget checks require a sales conversation or the plans page. Review features depend on ProtoPie Cloud, which adds a sharing step that local-only workflows avoid.

What is ProtoPie?

ProtoPie is an advanced prototyping tool for mobile, desktop, web, and IoT design. AI generates interactions, designers refine them without credit cost, and ProtoPie Cloud handles sharing, review, and approval so teams hand off interactive specs instead of static screenshots.

ProtoPie is an advanced prototyping platform built for teams that need their designs to behave like real products, not just look like them. It targets mobile, desktop, web, and even IoT contexts. The core pitch is that AI should assist the interaction work rather than guess at design intent: prompts produce interaction suggestions that a designer then edits, and those edits can be iterated without credit charges before anything is handed off as a clean specification. The workflow starts with the part designers already control. Layouts come in from tools such as Figma, Sketch, and Adobe XD, and the interactive logic is layered on top: triggers, responses, conditions, and variables. That variables system is central, since realistic behavior usually means state that changes as the user moves through a flow. ProtoPie Cloud carries the result to reviewers, who can open a shared prototype, comment, and approve it instead of reading static screenshots and written spec descriptions, which is the handoff pattern the product explicitly positions itself against. The audience is professional product and interaction design teams, especially those shipping multi-surface experiences where fidelity matters: apps, websites, connected hardware, and automotive interfaces. It suits designers who already understand interaction patterns and are willing to invest in tooling depth, since the value only appears once someone builds beyond linked screens. Teams trading in quick click-throughs may find the setup heavier than the task requires. Against general design tools, ProtoPie competes on interaction fidelity and on review-based handoff rather than on layout production. Against code, it competes on speed for stakeholder review before engineering is involved. Public resources include documentation, a learning site, a community forum, a prototype gallery, and a tips and tricks blog, plus an affiliate program. Pricing tiers and trial length are not stated on the homepage.

How do you use ProtoPie?

1Start a free workspace in ProtoPie Cloud
Create an account from the homepage and open ProtoPie Cloud. This is where prototypes get stored, shared, and reviewed later, so sign up before building anything local.
2Bring your screens in from your design tool
Import the layouts you already made in Figma, Sketch, or Adobe XD using the dedicated connection page for your tool. This keeps visual design work where it was done and moves only the prototype into ProtoPie.
3Generate interactions with AI, then edit them
Use the AI generation to propose the interaction you have in mind, then adjust the result by hand. Refinement of generated interactions is described as credit-free, so expect to iterate rather than accept the first output.
4Add variables for state and conditions
Move beyond single triggered events by defining variables that track state across the flow. The variables documentation is the place to start if triggers and conditions are new to you.
5Share the prototype for review and approval
Publish the prototype through ProtoPie Cloud so reviewers can interact with it, comment, and approve. This replaces the screenshot plus written description handoff described on the homepage.
6Work through guided lessons and browse examples
Use the learning site for structured lessons and the public gallery to see what high-fidelity prototypes look like when fully built out. Both are free to browse.

Pros and cons

Pros

Handles interaction logic, conditions, and variables, so prototypes can behave like the intended productAI
Explicit separation between AI suggestions and human editing, with credit-free refinement of generated interactionsAI
Review and approval happen inside ProtoPie Cloud, which gives stakeholders one place to respond to a working prototypeAI
Import routes from Figma, Sketch, and Adobe XD keep existing layout work usableAI
Materials for learning are substantial: documentation, a learning site, community forum, and prototype galleryAI

Cons

Steep learning curve for anyone without a grasp of triggers, variables, and conditional logicAI
No pricing tiers, plan limits, or trial length appear on the homepage, so budget checks require a sales conversation or the plans pageAI
Review features depend on ProtoPie Cloud, which adds a sharing step that local-only workflows avoidAI
Designers who only need linked-screen click-throughs are paying in complexity for capability they will not useAI
AI output still needs manual correction, so it shortens interaction work rather than replacing itAI
