About Overflow
[API Error: HTTPSConnectionPool(host='api.openai.com', port=44]
Overflow by PROTOIO is a specialized diagramming software crafted specifically for product and design teams who seek a more expressive, visual, and interactive way to present user flows and design logic. Unlike general-purpose diagram tools, Overflow offers a narrative-driven approach to presenting user journeys, making it easier for teams to not just show design screens, but to walk stakeholders through the “why” and “how” behind those designs. Built for clarity and collaboration, Overflow provides a sleek drag-and-drop interface that simplifies the process of linking design screens with connectors, annotations, and decision points. The interface is intuitive, visually clean, and optimized for visual storytelling, ensuring designers and product managers can focus on communication rather than technical layout concerns. With smart snapping tools and layout alignment features, the software helps maintain polished visuals with minimal effort. A major strength of Overflow lies in its seamless integration with design tools like Figma, Sketch, and Adobe XD. Users can import and re-sync their artboards directly from these tools, preserving layers, prototyping links, and visual fidelity throughout the design process.
