Free AI Detector
See how machine-like your writing reads, sentence by sentence, so you can add the variety and voice that make it sound like you.
What it looks for
The patterns that read as machine-written
Uniform sentence length
Human writing mixes short punchy sentences with long ones. Machine text often keeps everything the same length.
Generic transitions
Heavy use of moreover, furthermore and in conclusion is a common giveaway.
Vague, hedged claims
Statements that sound authoritative but commit to nothing specific.
Predictable vocabulary
Words like delve, tapestry, multifaceted and testament appear far more often in AI text.
FAQ
AI detector questions
Can this prove whether text was written by AI?
No, and neither can any other detector. It measures whether writing shows patterns common in machine text. Confident claims about authorship are not something any tool can honestly make.
Why did my own writing score high?
Formal, structured or technical writing shares surface features with AI text, and writing in a second language often does too. A high score means "reads uniformly", not "you cheated".
How should I actually use it?
Treat it as a style mirror. Look at the sentences marked red and add specific detail, vary their length, or put things in your own voice.
How many checks are free?
You get 10 free checks per day, with no account. The limit resets every 24 hours.
How long can my text be?
Up to 1,200 words per check. Analyse longer work a few paragraphs at a time.
