Frequently asked questions
How does the plagiarism checker work?
We use fuzzy matching algorithms to compare your text against billions of indexed web pages and academic sources. We catch both exact copies and paraphrased content.

No. Unlike some plagiarism checkers that add your text to their scanning database, we process your text in real-time and immediately discard it.

Plagiarism checking looks for text that matches existing sources. AI detection looks for statistical patterns that indicate AI authorship. They measure different things.
