Your users hit friction
you've never seen. We find it.
Heutrics is an AI UX auditor that crawls your app, generates diverse user personas, runs them through real browser sessions, and returns a scored report with evidence and fixes — in minutes, not weeks.

than manual UX audits
diverse user perspectives
Nielsen-based taxonomy
scored per persona & screen
UX problems are expensive to find
and easy to ship past.
Product teams know their app has rough edges. The hard part is knowing where, how bad, and who feels it first — before a user churns and tells you in a tweet.
Manual audits don't scale
Heuristic evaluations eat 2–6 weeks per app. By the time the report lands, the product has already shipped three more releases past it.
Your team tests like your team
Internal testers share the same mental model as the people who built the product. Real users — with different tech comfort, goals, and assumptions — hit friction you never thought to look for.
Lighthouse only catches the easy stuff
Automated tools flag contrast and alt-text. They can't tell you the CTA is buried, the onboarding is confusing, or a power user will rage-quit on step three.
Heutrics closes the loop — automated, persona-driven, and grounded in established usability heuristics.
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.
10 Core Heuristics
Every test is mapped to industry usability pillars ensuring evidence-based scoring rather than simple opinions.
Test Generator
Auto-generates persona-specific evaluation cases. A designer is tested on shortcuts; an owner on jargon.
- Screen x Persona test matrixScreen x Persona test matrix
- Severity-ranked (Critical to Low)Severity-ranked (Critical to Low)
- Custom test case support for edgesCustom test case support for edges
Execution Engine
Personas independently drive a real headless browser — navigating, clicking, and typing in parallel.
- Parallel multi-persona browser sessions
- Real-time DOM event streaming
- Live viewport screenshotting
Actionable reports, not just scores
Every audit delivers scored findings, screenshot evidence, persona-voiced feedback, and prioritized fixes your team can act on immediately.
“The error message just said invalid input — invalid how?”

Validated with the teams we're building for
We're in pre-launch. These quotes come from customer-discovery interviews with design, product, and UX research leaders — not paying customers yet.
“We do heuristic evaluations every quarter and it's a two-week black hole. If you could give me even 60% of that quality in a day, I'd pay for it.”
“The part I care about is persona diversity. Our internal testers all think like us — I need someone to show me what a 45-year-old who's never used SaaS sees.”
“Accessibility tooling tells me I have a contrast issue. It doesn't tell me the onboarding flow loses people at step three. That's the gap.”
Interviewee names withheld until public launch. Happy to make intros on request once we're live.
Questions people actually ask us
Straight answers. If yours isn't here, ask us directly in the enquiry form below.
Public beta opens Q3 2026. Design partners get access earlier — usually within 2 weeks of a discovery call. If you’re on the waitlist, you’ll get a dated email before anyone else.
Yes, while we’re in early access. The only thing we ask in return is feedback — a short form after your first audit, and optionally a 20-min call. No credit card, no trial timer.
Those tools detect technical violations (contrast ratios, missing alt text, Core Web Vitals). They can’t tell you that your CTA is buried, your onboarding confuses non-technical users, or a power user will rage-quit on step three. Heutrics simulates real users with goals and frustrations, then grades the experience — not just the markup.
Heutrics handles standard signup flows (email, Google/GitHub OAuth in most cases) and detects CAPTCHA/OTP walls when it can’t proceed. For deeper authenticated flows, design partners can provide test credentials we store encrypted. Full SSO support is on the Pilot tier.
We only crawl what’s publicly reachable or what you explicitly authorize. Sessions are isolated, screenshots and recordings are stored against your account only, and you can delete any audit at any time. Pilot-tier customers get a DPA and security review.
Yes — that’s essentially what design partnership is. Tell us about your product in the form below, and if it’s a fit we’ll run a hand-paired audit within 10 business days and walk you through the results personally.
Totally fine. We publish build-in-public updates roughly every two weeks. Drop your email and pick “just keep me posted” — we won’t pester you.
Tell us about your product. We'll tell you what to audit first.
Fill this in and one of us (a real person, not a sequence) will reply within 48 hours. If you're a fit for design partnership, we'll book a 20-min call and run your first audit on the house.
