Sprint Reviews
Pressure-test new UI before sprint demos. Catch confusing flows and unclear CTAs before they reach stakeholders or users.
Prototype Testing
Validate prototypes at any fidelity. Get persona-specific feedback on whether your design communicates its intent clearly.
Pre-Handoff Checks
Run a final AI usability pass before handing off to engineering. Surface friction points that are cheap to fix in design but expensive in code.
Solo Designer Validation
When you do not have a researcher or spare users available, get an immediate outside perspective on your design decisions.
Slow Feedback Loops
Traditional usability testing takes days to recruit, schedule, and synthesize. By the time results arrive, the design has already moved on.
High Testing Costs
Recruiting participants and running moderated sessions is expensive, so most design decisions go untested until it is too late to change them.
Context Switching
Exporting designs, setting up external tests, and importing results back breaks the design flow and slows iteration cycles.
Assumption Blindness
Designers are too close to their own work to spot confusing flows and unclear CTAs that will trip up real users.
Instant In-Plugin Feedback
Select any frame in Figma, ask your research question, and receive specific AI feedback in seconds — no exports, no scheduling, no waiting.
Persona-Based Testing
Choose the user persona most relevant to your design and get feedback calibrated to their goals, mental models, and likely friction points.
Assumption Validation
Surface risky product assumptions baked into your UI before they reach users — confusing navigation, unclear value propositions, and onboarding gaps.
Rapid Iteration
Make a change and retest in seconds. Tight AI feedback loops mean you can validate multiple design directions in a single session.
Why use UI Roast in Figma
Stay inside Figma
Select frames, choose a persona and ask a research question. Get feedback without exporting designs to another tool.
Check early flows
Spot confusing flows, unclear CTAs, onboarding friction and risky assumptions before a heavier research round.
Compare design directions
Run the same question across different frames or variants. See what the feedback flags before you commit.
Complements live testing
UI Roast does not recruit participants or run live voice sessions. It gives AI feedback on the frames you select, so real user testing can focus on deeper questions.
