Do Usability Heuristics of your App or Website.
Upload your screens, paste a URL, or connect Figma. Get a structured expert review against ten evolved Nielsen heuristics — severity-rated findings, user impact, and concrete fixes — in minutes instead of days.
Evaluations run on Claude. Your files stay private to your account.

Payment failure shows a generic error with no recovery path
Screen 5 displays “Something went wrong” without stating what failed or preserving the entered card details.
Fix: Name the failing step, keep form state, and offer “Retry” and “Use another method” actions inline.
Any format your flow lives in
Order matters for a flow. Number your files, draw arrows, use a prototype — we read the sequence and evaluate transitions as well as screens.
Screenshots
JPG or PNG screens. Number them 1, 2, 3… or draw arrows to mark the flow and we'll follow it.
Export your flow as a PDF — every page is read as a screen, in order.
Live website
Paste one or more URLs. We capture desktop or mobile views with a real browser, section by section.
Figma
Connect Figma and paste a design, prototype, section, or frame link. Prototype connections define the order.
Three steps to a full evaluation
- 1
Add your screens
Upload screenshots or a PDF, capture a live website, or import frames from a Figma link.
- 2
Describe the flow
Tell us the product, its users, and the task the screens represent. Reorder screens if needed.
- 3

Findings per heuristic with severity and impact, priority fixes, and what already works.
Ten evolved Nielsen heuristics
Nielsen's classic heuristics, re-framed for products where the system is probabilistic and collaborative — and adapted automatically when your product isn't AI-driven.
- Every finding rated Critical, High, Medium, or Low with a user-impact category
- Evidence tied to specific screens and interface elements
- Actionable recommendations that explain how to fix, not just what's wrong
- Flow analysis across the sequence of screens
- Top priority actions and what already works well
- Export as Markdown or JSON for your team
