Question 4

What is word-level AI highlighting?

Question 5

Accepted Answer

Yes, all AI detectors can produce false positives — flagging human-written text as AI-generated. This is more common with formal, technical, or non-native English writing. Our rewrite suggestions help you fix flagged sections.
