Check your textHow to read your AI detector score
The AI detector gives you a single number from 0 to 100. It is the estimated chance that AI wrote the text, not a yes or no. Here is what each band means.
Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.
How the AI essay checker works
Three steps, a few seconds, no setup.
Add your text
Paste it, upload a Word or PDF file, or drop in a link to the page you want to check.
We check the patterns
The model weighs your essay against the patterns of AI writing and human writing.
Read the score
You get a number from 0 to 100 and a plain read on how likely AI was involved.
Why check an essay for AI
More schools run submissions through AI detection, and the results can be hard to argue with after the fact. Running your own essay first tells you whether parts of it read as machine-written, whether you leaned on a tool more than you meant to, or whether a quoted passage looks generated. It is a chance to revise on your own terms.
What a high score means for your essay
It means parts of the writing match patterns AI tends to produce, not that you have done anything wrong. Honest writing sometimes scores high, especially formal, careful prose. Read a high score as a prompt to look closer at those sections and put them more clearly in your own voice.
Upload the whole paper
Paste the text, upload a Word or PDF file, or drop in a link. For a long paper the checker splits it into sections, scores each, and averages the result, so one formal paragraph does not skew the whole reading.
Where your essay goes
The check happens in memory on our own server. As soon as you have a score, your essay is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
