Example use cases
Onboarding flow usability audit
“I just built a new user onboarding flow — users sign up, verify email, then set up their profile. Here's a description of each screen and what users are trying to do. Can you give me a detailed UX critique and tell me where people are likely to drop off?”
Checkout form UX review
“Here's the HTML for my e-commerce checkout page. Users are trying to enter their shipping address and payment details and complete their purchase. What UX problems do you see and how should I fix them?”
Dashboard navigation critique
“My SaaS dashboard has a left sidebar with 12 menu items, a top nav with account settings, and a main content area with data tables. Users are trying to find their reports and manage their account. Can you critique the navigation design and tell me what's not working?”

Endpoint
POSThttps://superdesigner.supercapital.fun/ux-critique?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need expert-level UX critique and design feedback on a specific screen, flow, or HTML interface — particularly when you want structured, actionable recommendations rather than generic design tips. Best for product designers, developers, or agents building product feedback loops who need fast per-screen analysis rather than a full design audit tool.
Side effects
- Empty or too-short input description returns validation error
- Input exceeding 8000 characters is rejected
- Ambiguous or context-free descriptions may produce generic feedback
- Payment failure results in 402 response before processing begins
- Network or timeout errors may delay or fail job completion
