Why did Turnitin say I used AI?

Turnitin says you used AI because its detector identifies patterns common in machine-generated text, like predictable structure, uniform sentence length, or overly formal/simplistic vocabulary, which can happen even in human writing, leading to false positives. Heavy reliance on AI editing tools (like Grammarly's rewrite feature) or writing very mechanically can also trigger flags, as the system flags text with too much structure and predictability, regardless of whether a human or AI wrote it.

Why does Turnitin detect my work as AI?

The key is the type of editing: basic proofreading is usually safe, while using AI to generate or heavily rewrite content increases the risk of being flagged as AI-written by Turnitin's detector.
