Free AI content detector
See which passages of your text sound like a machine, and why.
A passage sounds like a machine? Run it through the AI text humanizer to make it more natural, then test it again. Or write your whole book with Makebook, in your own voice.

AI-written text shares recognizable habits: sentences of very even length, stock connectors ("moreover", "furthermore", "it's important to note"), almost systematic lists of three and conclusions that moralize. This detector shows you those patterns in your own text.
What makes a text human is mostly lived detail: an anecdote, a precise number, a firm opinion, a slightly lopsided sentence that sounds like you. If the analysis flags a generic passage, the best answer is almost always to slip in an example from your own life.
Keep in mind that no detector is 100% reliable. Use this one to spot the passages to rework, then read aloud: if you'd never say that sentence that way, rewrite it.
Frequently asked questions
Is an AI detector 100% reliable?
No, none is, even the paid ones: they regularly get it wrong, in both directions. Treat the result as a reading clue, not a verdict.
Why don't you show a percentage?
Because a percentage gives a false impression of precision. We prefer to give you a clue and show you the exact passages that sound like a machine, which really helps you rework them.
Can human-written text be flagged as "AI"?
Yes, especially if it's very smooth, very formal or written in a language that isn't your first. That's why it's better to look at the flagged phrasing than at the score.
Is my text stored?
Your text is only used to produce the analysis shown. It isn't published and you can remove it from the page at any time.
