See a sample reportEvery founder hits this wall.
You launch, you wait, nothing happens.
You spent weeks on the copy. You tweaked the CTA. You changed the headline three times. The page still isn't converting and you have no idea why.
Friends say it looks great.
You ask your network for feedback. You get "looks good!" You post in Slack. Two people respond. None of them are your actual customer.
You can't afford to burn ad spend finding out.
Running traffic to a broken page is expensive. Real user testing takes weeks and costs thousands. You need answers before you spend.
From gut feeling to actual data in 2 minutes.
Paste your landing page URL
Live site or uploaded HTML. WhyIQ reads your page exactly as a first-time visitor would see it.
50 simulated visitors read it
Each one arrives with different psychology: skeptical, price-sensitive, time-pressed, or comparison shopping. Same distractions your real visitors bring.
Read the WHY, not just the score
See which elements confused visitors, what they missed, and what made them leave. Each issue is tied to a specific page element and a specific fix.
Fix it, rescan, see the improvement
Change one thing. Rescan. Watch your clarity score go from 47 to 79. Then share the before/after on X or IH.
What you get from every scan.
Clarity score (0-100)
A single number that tells you how well your page communicates its value to a first-time visitor. Fix issues, rescan, watch it climb.
Before/after comparison

Shareable results

Questions
Do I need traffic for this to work?
No. WhyIQ works on any page with zero traffic. You can even upload an HTML file and test before you launch. This is the entire point: get feedback before you spend on traffic, not after.
How is this different from asking a friend or posting in Slack?
Friends give you polite feedback. WhyIQ runs 50 simulated visitors with different psychology, patience levels, and intent, then quantifies how many would bounce and exactly why. It tells you what confused the skeptics, what the price-sensitive visitors missed, and what the impatient ones never reached.
What does a clarity score actually measure?
It measures how clearly your page communicates its value proposition to a first-time visitor. Specifically: what percentage of simulated visitors understood what your product does, who it's for, what they should do next, and why they should trust you. A score above 70 means your core message is landing. Below 50 means most visitors are leaving confused.
Can I test a page before it's live?
Yes. Upload an HTML file directly and WhyIQ will analyse it. Perfect for testing before launch, before running ads, or before a product hunt listing.
How many free scans do I get?
3 free scans per month with no credit card required. Each scan gives you a full clarity score, top confusion points, and ranked recommendations. Paid plans start at $39/month for 20 scans.
