Eight signals — stock phrases, rhythm, paragraph shape, the em-dash habit and more — each with a plain sentence explaining it.
Questions people ask
- Can any tool prove a text was written by AI?
- No — and be suspicious of any that claims it can. This checker reports mechanical signals machine-written text tends to leave behind: stock phrases, uniform sentence length, heavy em-dash use, no concrete details. A careful human editor can remove them; a careless human writer can trip them.
- Is what I paste stored or sent anywhere?
- No. The analysis runs entirely in your browser, in code. There is no upload and no model call, so the same text always gets the same report.
- Why do I need a free account for the full report?
- The first three signals are open to everyone. The full eight-signal report is part of Yolect, and a free account is how we keep the tool from being scraped. No card is needed.
- What do I do if my own writing gets flagged?
- The signals are fixable habits: break the even rhythm, cut the stock phrases, add one detail only you could know. Yolect's editor guides you through exactly that — from your own voice note, not a blank box.
Detecting machine text is one thing. Never sounding like it is another.
Yolect starts from your voice note or rough thought, learns how you actually write from your published posts, and grades every draft against these same signals before you see it. 25 free generations a month — Pro when you want more.
