Questions people ask

Learn moreCan TextHumanizer check if text is AI-generated?
Yes. Paste the text and tap Check for AI. You get a percentage for how likely the text is to be read as machine-written, so you can decide what to edit.
Learn moreDoes Turnitin detect ChatGPT?
Turnitin flags a lot of unedited ChatGPT text and added a check for humanized text in 2025. It also makes mistakes, which is why many universities say the score alone is not proof.
Learn moreWhy was my own writing flagged as AI?
Detectors score predictability. Plain, formal or carefully edited writing can look predictable, and research has found higher false-positive rates for non-native English writers.
Learn moreIs using an AI humanizer cheating?
It depends on your school's or employer's rules for AI tools. Using it to polish your own AI-assisted draft is allowed in many settings. Submitting work you did not do usually is not.
Learn moreWhat is the difference between a humanizer and a paraphrasing tool?
A paraphraser swaps words and reorders clauses. A humanizer targets the patterns detectors look for, such as uniform sentence length and stock phrases.
