AI-powered usability feedback for your website, right in your browser
Run an AI assessment on the page you are viewing straight from the browser toolbar — no enrolment, scheduling or participant management required.
Feedback is written as concrete suggestions for layout, clarity and flow, so you can move straight from reading to editing.
The AI frames its critique around how your intended users would experience the page, rather than abstract design rules.
An optional sharper, humorous review style keeps repeated testing sessions from feeling dry.
