Everything you need to audit UX at scale
From discovery to delivery, Heutrics automates the entire UX audit pipeline — replacing weeks of manual work with AI-driven precision.
Automated Screen Discovery
Headless browser crawling maps every screen — L1 navigation, L2 sections, L3 deep pages — with thumbnails and depth classification.
AI Persona Generation
Generate 3–5 diverse personas from app context — each with unique goals, frustrations, tech comfort, and behavioral patterns.
Real Browser Automation
Real Chrome sessions — filling forms, navigating flows, detecting CAPTCHA walls, recording every step as an animated GIF.
Heuristic Test Cases
Auto-generated tests per screen and persona, tagged with visibility, feedback, accessibility, learnability heuristics.
Thought Simulation
Personas narrate their experience — surfacing confusion, delight, and frustration as an inner monologue in their own voice.
Scored UX Reports
Composite 0–100 score with persona breakdowns, severity ratings, screenshot evidence, and AI-generated fix recommendations.
From URL to UX report in five steps
What used to take a research team weeks now happens automatically.
Paste Your URL
Enter any web app URL. We fetch the landing page, detect signup flows, OAuth options, and navigation — all automatically.
- Intelligent link scoring
- Signup flow analysis via LLM
- CAPTCHA & OTP detection
Discover Screens
A headless browser crawls your app, discovering every screen with viewport screenshots and depth classification.
- L1/L2/L3 page hierarchy
- Automatic thumbnailing
- Complete page tree
Generate Personas
AI creates 3–5 diverse personas with distinct goals, frustrations, and behavioral patterns from your app context.
- Demographically diverse
- Fully editable
- Test email auto-assignment
Run Tests
Each persona navigates your app in a real Chrome browser — filling forms, clicking through flows, recording sessions.
- Real Selenium sessions
- GIF session recordings
- Smart field detection
Get Report
A scored UX report with severity ratings, heuristic tags, persona feedback, screenshot evidence, and fix recommendations.
- 0–100 composite score
- Per-persona breakdowns
- Prioritized fix list
See your app through every user's eyes
AI personas don't just test — they think, react, and voice frustrations like real users. Each brings a unique perspective shaped by their goals and expectations.
Sarah K.
Product Designer, 28
Designs SaaS tools daily. Expects keyboard shortcuts, fast feedback loops, and zero friction onboarding for power users.
Goals
- Find design tools quickly
- Collaborate with team seamlessly
- Export assets without extra steps
Frustrations
- Cluttered, noisy interfaces
- Slow or missing loading states
- No keyboard shortcut support
“I abandoned the onboarding because there was no way to skip the tutorial. Power users don't need a 5-step walkthrough.”
Personas are fully editable — add custom ones, regenerate on demand, or refine attributes to match your exact audience.
Grounded in usability heuristics
Every finding is tagged with established UX heuristic categories — structured, evidence-based analysis, not just opinion.
Test Generation
For every screen, Heutrics generates test cases personalized to each persona. A designer gets keyboard shortcut tests; a business owner gets jargon-free navigation checks.
- Screen x Persona test matrix
- Severity-ranked: critical / high / medium / low
- Heuristic tags per test for structured analysis
- Custom test case support for edge cases
Execution Engine
Each persona independently drives a real browser — navigating, clicking, typing — while AI generates their inner monologue in real time.
- Multi-persona parallel browser sessions
- Real-time event streaming: navigate, click, input
- Persona thought simulation during navigation
- Live viewport screenshots & session recording
Actionable reports, not just scores
Every audit delivers scored findings, screenshot evidence, persona-voiced feedback, and prioritized fixes your team can act on immediately.
Persona Scores
Top Issues
Persona Feedback
“The error message just said 'Invalid input' — invalid how? I entered my phone number the way I always do.”
“Love the clean layout, but the 'Save' button is invisible against the background until hover.”
Fix Recommendations
Add inline validation with specific error messages beneath each field
Increase button contrast ratio to 4.5:1 minimum per WCAG
Executive Verdict
2–3 sentence summary for stakeholders — no jargon, just actionable insight.
Screenshot Evidence
Every issue paired with a screenshot — see exactly what each persona encountered.
Re-test Comparison
Before vs. after scores side by side with delta improvements after fixes.
Trusted by product teams shipping better UX
“Heutrics found accessibility issues in our signup flow that our manual QA missed for months. The persona-based approach surfaces things you don't even think to test.”
“We replaced two weeks of heuristic evaluation with a single Heutrics audit. The severity-ranked issues made prioritization effortless for our sprint planning.”
“The persona quotes alone are worth it — they give stakeholders empathy-driven context that raw bug reports never could. Our execs actually read these reports.”
