Overflow

Overflow lets design teams turn static mockups into interactive user‑flow diagrams and presentation‑ready stories. Users can import screens from any design tool, arrange them on a canvas, and then switch to a prototype view for screen‑by‑screen navigation or a story view that guides viewers through a self‑paced walkthrough. The tool adds visual cues, branding, and styling options without altering the original designs, making complex product journeys easier to map and discuss.

The platform is built for macOS and targets designers and product managers who need to keep design files tidy while sharing work with teammates or clients. It supports real‑time and asynchronous critique, allowing feedback to be gathered without lengthy email threads or meetings. Syncing works after each design iteration, ensuring presentations stay current with minimal manual effort.
