Copyleaks vs Turnitin
Copyleaks markets a high headline accuracy for AI detection, and many institutions run it alongside or instead of Turnitin. The catch for students is the same as with every detector: a confident percentage is still a probability, not proof, and Copyleaks has been shown to false-positive on human writing — including, in widely-shared tests, classic public-domain texts and formal student essays.

Turnitin is more entrenched in higher education and integrates directly into the assignment dropbox most students already submit through, so it's usually the one whose verdict actually lands on your record. Copyleaks tends to surface in plagiarism-plus-AI workflows and some corporate settings. If your school uses one, your draft needs to clear that specific tool — and the only way to know is to check before you hand it in.
The free detector below reads Turnitin, GPTZero and Originality so you can gauge your exposure without paying for multiple subscriptions. Results vary, so treat the read as a guide rather than your institution's official result. Where a passage reads high, the Powerful Model clears that risk and makes it read as human while protecting your citations and argument — under the Green-Or-Free guarantee: it passes or your money back.
