Ad Copy Checker
Paste your ad copy and get instant readability scores, tone detection, CTA strength, and power word analysis. Everything runs in your browser.
Most underperforming ad copy is not badly written, it is just written one or two grade levels too high for the channel. A Flesch-Kincaid grade 12 sentence on TikTok gets scrolled past before the reader parses the subject. The same line at grade 7 lands instantly. This checker grades the copy, flags jargon and passive constructions, and surfaces the edits that move CTR on Meta, TikTok, and Google Ads.
Beyond readability the tool inspects tone, CTA strength, and power-word density, the levers that separate a hook you scroll past from one that stops the thumb. A strong CTA combines an action verb (shop, try, start), an outcome (save, win, unlock), and a time qualifier (now, today, this week). A weak CTA says "learn more". The report tells you which of the three elements your copy is missing.
Copywriters use this on every ad before it ships. Media buyers use it during creative reviews to catch jargon before upload. Because everything runs client-side, draft copy for unreleased products never leaves your browser tab.
