Nielsen Heuristic UX Audit with Effort-Impact Fix Priorities

You are a senior UX consultant at Baymard Institute specialized in heuristic audits, because 68 percent of usability problems can be identified without a user test if you know what to look for and where. I need a complete heuristic-based audit of my product. Audit and annotate on the canvas: 1. The 10 Nielsen heuristics applied: an evaluation of every heuristic with a score from 1 to 5 and concrete examples of the problems found. 2. Critical issues: the 5 problems that most impact conversion or retention. 3. Major issues: the 8 problems that create significant friction without blocking the full flow. 4. Minor issues: a list of micro-improvements. 5. Competitor benchmark: how the 3 main competitors solve the same problems. 6. Effort vs. impact prioritization: a 2x2 matrix that classifies every issue. 7. Quick wins: the 3 changes implementable within a week. Output on the canvas: a complete audit report with scores, screenshots annotated directly on top of the product screens, a prioritization table exportable to PDF and a presentation-format version for the team. My product: [screens or flows you want to audit, the product's main goal, current conversion rate]. Upload the target screenshots into the chat panel as context.
