Hey Product Hunt 👋 I’m Emine, the maker of Heurilens. Heurilens is an AI-powered UX analysis tool that evaluates any website using Nielsen’s heuristics, UX laws, and cognitive psychology — and turns the findings into instant, actionable recommendations to improve UX and conversion rates. 💡 Just paste a URL → get a structured UX audit in seconds. I’d love your feedback: Which part of your website do you want to improve first — trust, clarity, navigation, or forms? Thanks for checking it out 🙏

Love the focus on Nielsen’s heuristics and UX laws. Curious how the tool prioritizes issues by impact on conversion vs. usability?

@mohammed_fazalur_rahman Great question — this is actually one of the core problems Heurilens is built to solve.

Heurilens doesn’t treat all UX issues as equal.

Each finding is evaluated across two parallel dimensions:

1️⃣ Usability impact (heuristics & UX laws)
We map every issue to Nielsen’s heuristics and cognitive UX principles (clarity, feedback, error prevention, consistency, etc.) to understand how much friction it creates in task completion.

2️⃣ Conversion relevance (behavioral & intent signals)
In parallel, we look at where the issue appears (hero, CTA, form, pricing, navigation) and what user intent is present in that section. Issues closer to decision-making or action points are weighted higher for conversion impact.

Instead of a single generic score, Heurilens outputs:

  • Section-based insights (what breaks UX and where)

  • Impact labels (high usability risk vs. high conversion risk)

  • Clear prioritization: what to fix first depending on your goal (reduce friction vs. increase conversion)

So a minor visual inconsistency won’t outrank a CTA visibility issue — even if both are “usability problems.”

The goal isn’t to list issues, but to turn UX signals into decision-ready priorities.
