How scoring works
Copy Grader is fully rules-based. No AI reads your text, and it never leaves your browser.
Every score starts at 100. Six categories subtract points when they find AI-writing tells: stock AI phrases, luxury cliches, weasel words, punctuation habits, repeated words, and flat sentence rhythm. Each category has a capped maximum deduction, so one bad paragraph cannot sink the whole score. A seventh category, specificity, adds up to 10 points back for concrete facts: metal purity, measurements, stone names, hallmarks and lead times. Length is checked separately against the 60 to 200 word sweet spot for a product description. The final score is clamped between 0 and 100.
- 85 and above: Sounds human
- 70 to 84: Minor tells
- 50 to 69: Reads AI-ish
- Below 50: Heavy machine accent
