How it works
We read your text the way a very well-read, very literal editor would, and tell you how closely it resembles the writing AI tends to produce. Here is every step, and what we do not do.
-
You paste, we split
The text is cut into paragraphs so each gets its own reading. A paragraph under about 50 words is joined to the next, because a few lines are too little to read. Texts under about 150 words get a warning: fewer words, wider uncertainty.
-
A model reads each paragraph, on our own hardware
A language model measures how predictable each passage is, word by word, compared with how a second model expects it to go. Writing AI produced tends to be smoother and more expected than writing people produce. The model runs on a server we own. Your text is not sent to an AI company, and it is not stored.
-
You get a probability and the why
One number for the whole text with its likely range, a label for each paragraph, and up to three plain observations behind each label, written so you can check them with your own eyes.
What it notices
Rhythm
Shown as “Very even sentence lengths”
People vary sentence length a lot: a long one, then a short one. AI drafts tend to keep an even beat.
Predictability
Shown as “Predictable word choices”
How often the next word is the expected one, and how often the same words come back. Surprise reads human.
Connectives
Shown as “Stock connective phrases”
“Furthermore”, “Moreover”, “It is important to note” as the glue between sentences, again and again.
Shape
Shown as “Tidy template structure”
Paragraphs that open with “Firstly” and close with “In conclusion”, the shape of a school template.
None of these is proof. Good human writers do all of them sometimes, which is why the answer is always a probability with a range, never a verdict.
What it does not do
- It does not know who typed the words. It knows how they read.
- It does not rewrite your text or help any text slip past a detector, and it never will.
- It does not compare your text with other sources or look for copied passages.
- It does not read languages other than English, for now.
