How does the human score work?
We analyze sentence rhythm, word choice, hedging, stock transitions, and other patterns that separate machine text from human writing, then score the text 0–100. 100 reads like a skilled human writer; below ~70 usually gets side-eyed as AI.
Is this an AI detector?
It's the reverse of one. Detectors guess whether a machine wrote your text; we tell you how it reads to a human — and exactly which phrases are giving it away, so you can fix them.
Is it really free?
Yes — 5 checks a day, no account. If you want to fix a low-scoring text, a free rephrase.io account rewrites it in one click, 30 times a month.
