Stunt Double vs Versive

Versive is a user research platform with two halves. AI tests send AI personas through a Figma prototype, a live website or a set of images and return transcripts, screenshots and recommendations. AI-moderated studies run interviews with real participants you recruit, by text, voice or video. Versive itself says AI test findings are directional until real participants confirm them.
