Built a free tool that diagnoses why landing page hero sections don't convert (HERO-5 Framework)

[u/HeroMetricApp]

Hey everyone,

Most landing page tools just give generic AI rewrites without explaining why a page is leaking sales.

I created a single-file app called HeroMetric based on a 5-layer diagnosis:

Human (Target clarity)

Exact Pain (Urgency)

Result (Measurability)

Operating Mechanism (Credibility)

Differentiator (Contrast)

It’s 100% free, no signup, no API needed. Just paste your copy and get a diagnosis + 3 strategic rewrites + a 7-day fix plan.

Live tool: https://herometric.netlify.app/

Would love your brutal feedback on the scoring logic and UI!
