GPTZero and its alternatives, compared
Traffic figures are estimated US organic visits per month, measured September 2026. They are a proxy for how many people actually use a tool, the one number in this market nobody can fake in a listicle.

|---|---|---|---|
| TextAsMe | Free, unlimited | New | Explains every flag |
| GPTZero | Free tier; paid plans for volume and API | 4,517,328 | 7,326 |

What GPTZero does well
4.5 million US organic visits a month and the most recognised name in AI detection, with 10,498 referring domains behind it.
Where it falls short
Like every detector, it produces false positives, and it reports a verdict without telling the writer which habit produced it.
The verdict
Useful as a second opinion, dangerous as evidence. If you have been flagged by it, what you need is a sentence-level account of why, not another percentage.
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.
