Overflow

Overflow is a specialized user flow diagramming tool designed to help product designers and teams create interactive presentations from their existing designs. Think of it as a bridge between your design tools and your presentation needs.

The main difference from other diagramming tools is simple: instead of building flows from basic shapes, Overflow uses your actual design screens and connects them with smart connectors. It integrates seamlessly with popular design tools, allowing you to sync artboards and automatically transfer layers without recreating anything.

Each user flow includes interactive elements, device skins, annotations, and smooth navigation features. Founded by the team behind Proto.io, this tool has gained popularity among 500,000+ designers worldwide because it saves time and creates more engaging presentations. You can present your designs like a story, switching between bird's eye view and detailed screen-by-screen walkthroughs.
