UXtweak

UXtweak is an all-in-one user research and usability testing platform offering moderated and unmoderated studies, card sorting, tree testing, prototype testing, preference tests, five-second tests and session recordings from a single workspace.

The platform pairs a 155M+ tester panel with a powerful study builder, video recording and AI-assisted analysis.

• Full research toolkit covering card sorting, tree testing, prototype and preference tests
• Moderated and unmoderated studies with video, audio and screen recording
• Figma and Sketch prototype support for design validation before engineering spend
• 155M+ global tester panel with demographic, behavioural and professional filters
• Session recordings and heatmaps on live websites and mobile apps
• AI-assisted analysis summarising open-ended responses and tagging themes
