Lyssna is a remote user research platform that helps product and design teams validate design decisions quickly through a suite of unmoderated test types. Formerly known as UsabilityHub, the platform rebranded in 2023 to reflect an expanded vision for continuous product discovery. Core test formats include preference tests for comparing design variations, first-click tests for evaluating navigation and layout clarity, five-second tests for measuring first impressions, and prototype tests for validating interactive Figma and other design tool prototypes. Each test type produces quantitative results that can be shared as polished reports with stakeholders.
