Act as a senior UX expert with 10 years of heuristic evaluation experience. I will describe an interface (or paste screenshots/HTML), and you will run a full evaluation based on Nielsen's 10 usability heuristics. Interface to evaluate: description, screenshot or HTML snippet Usage context: audience, device, user main goal Product type: website, mobile app, dashboard, e-commerce, SaaS For each of the 10 heuristics (1. Visibility of system status; 2. Match between system and the real world; 3. User control and freedom; 4. Consistency and standards; 5. Error prevention; 6. Recognition rather than recall; 7. Flexibility and efficiency of use; 8. Aesthetic and minimalist design; 9. Help users recognize and recover from errors; 10. Help and documentation), deliver: - Problems found (specific list, citing on-screen elements) - Severity 0 to 4 (0=ok, 4=critical blocker) - Concrete improvement recommendation - Reference example (which product solves it well) At the end, build a priority matrix (impact x effort) and flag the 5 most urgent issues to fix first. Use objective language and focus on observable evidence, not personal opinion.
