What Semrush AI Detector does well
A free detector attached to a 2.0 million-visit SEO platform with enormous domain authority.
Where it falls short
Detection is a lead magnet for the core product, not a maintained priority.
The verdict
Convenient if you are already a Semrush customer. Not built for writers.
Where TextAsMe differs
Every tool above returns a score or a rewrite and stops. TextAsMe marks each sentence, names the signal that fired on it, metronome rhythm, low perplexity, dead metaphor, stock transition, no concrete detail, and rewrites toward a measurement of your own writing rather than a generic human average. The writing analysis and your Style DNA run in your browser, and the text you check for a real AI score is never stored.
Semrush detector alternatives are Originality.ai, GPTZero, Copyleaks and TextAsMe.
TextAsMe scans for free with no account and no word cap, showing every flagged sentence and why. The studio and humanizer are paid, $9 a month (Starter), $18.50 (Pro) or $50 (Elite), half price billed yearly. GPTZero also has a free tier.
