What's the difference between Plagiarism Detection and AI detection?
Plagiarism detection and AI detection solve two different problems:
| Plagiarism detection | AI detection | |
|---|---|---|
| Purpose | Finds text that already exists elsewhere. | Identifies text generated by AI models. |
| How it works | Compares your document against databases, academic journals, and the open web. | Uses language models trained on billions of human + AI samples to spot statistical AI patterns. |
| Best for | Academic integrity, SEO duplicate-content checks. | Verifying originality of freshly written content. |
| Limitations | Won’t flag AI text if it isn’t copied. | Won’t flag human-written text that was copied from another source. |
Use plagiarism detection when you suspect the text was copied. Use AI detection when you suspect the text was drafted by ChatGPT, Claude, Gemini, or another model — even if it’s original wording.
