What GPTinf does well
One of the earliest paraphrase-based humanizers, still pulling 50,567 US visits a month.
Where it falls short
The synonym-substitution approach is exactly what modern detectors were retrained to catch.
The verdict
Dated approach. Test its output against a current detector before you subscribe.
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.
GPTinf alternatives are Phrasly, Undetectable AI, Walter Writes 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. Walter Writes AI also has a free tier.
Reported from about $12/mo. Prices were read from vendor pricing pages in September 2026 and change often, check before you subscribe.
