Moio

Moio is a product design tool that unifies interface design and interaction prototyping in a single environment. Its primary purpose is to let teams design, simulate, and validate real product behavior, not just static screens. By enabling designers to create functional flows that closely mirror the final product, Moio helps reduce misalignment between design, engineering, and product stakeholders.

Moio supports the full journey from wireframes to high-fidelity interactive prototypes. Designers can define screen layouts, component states, and complex interactions such as conditional logic, multi-step flows, and dynamic navigation. Built-in flow visualization allows teams to see and adjust the entire user journey, ensuring edge cases and alternative paths are accounted for. Because interactions are defined directly within the design, prototypes can be tested quickly with users to validate usability, timing, and behavior before development begins.
