About this skill
About Ad variant generator
Ad platforms reward advertisers who test many variants, but writing twenty headlines inside strict character limits is slow and repetitive. This skill writes ten variants across five angles — pain, outcome, proof, objection and urgency — and shows the character count of every line, so nothing gets rejected at upload. Urgency is only used when your offer genuinely ends, and it never invents numbers or testimonials. It also picks the two variants with the clearest contrast to test first and tells you what to measure, so the test teaches you something instead of just spending budget.
