Marvel App adds JourneyGPT to auto-generate user flows from specs

Design · 4 min read

Marvel App introduced JourneyGPT, a feature that ingests product specs, user stories, and acceptance criteria to auto-generate interactive user flows and clickable prototypes. JourneyGPT maps narrative steps to screens, proposes microcopy, and links interactions to produce a testable prototype quickly.

The tool exports interaction maps and allows designers to edit generated flows directly in the canvas, preserving a clear lineage from the original spec to the prototype. Marvel also provides analytics hooks so teams can run usability tests on AI-generated flows and iterate based on real user feedback.

Product teams value JourneyGPT for lowering the barrier between idea and prototype, but designers stress the need to refine layout and accessibility details post-generation. Marvel plans to add integrations with usability testing platforms to close the feedback loop.
