The Arclen Headline Scanner is a free AI-powered tool that grades headlines on a 0-100 scale across five conversion dimensions: clarity, specificity, desire, believability, and uniqueness. According to research from CXL Institute, headlines account for up to 60% of landing page conversion variance. The tool provides instant scoring plus a production-ready rewrite using direct-response copywriting frameworks. No signup is required.

What we grade your headline on.
Five dimensions, scored 0–100. The same framework the instrument runs on every full-page diagnosis.
Clarity
Can a distracted visitor understand your offer in five seconds?
Specificity
Do you promise concrete outcomes, numbers, or timeframes?
Desire
Does it trigger curiosity or a specific, felt want?
Believability
Does it sound credible — or does it trip the BS detector?
Uniqueness
Does it stand out from the generic alternatives in your market?
Questions? Answered.
Generic tools rewrite for tone. Arclen grades against the same conversion frameworks the instrument uses on full pages — clarity, specificity, desire, believability, uniqueness — then shows you exactly which one is leaking before it hands back a rewrite. You get the diagnosis, not just a different-sounding sentence.
Anything 78+ is in good shape; 60–77 is workable but leaking conversions; under 60 needs work. The score is a weighted blend of the five dimensions — clarity carries the most weight, because a headline nobody understands can't convert no matter how clever it is.
No. The score, the dimension breakdown, the issues, and the rewrite are all instant and free — no signup, no card. Everything happens right in your browser.
Yes. The five dimensions apply to any short, high-stakes line of copy — ad hooks, subject lines, hero headlines, even button labels. The shorter and more consequential the line, the more the grade tells you.
It runs a direct-response rubric over your headline — checking word count and clarity, concrete numbers and timeframes, reader-focused framing, hype that trips the BS detector, and clichés that make you sound like everyone else — then weights the five dimensions into a single 0–100 score.
As many as you like — clear the field and scan again. Founders typically run five or six variants back-to-back and ship the one that scores highest across clarity and specificity.
