How accurate is AI-based plagiarism detection?

The AI detects style inconsistencies, common phrasing from known texts, and segments that appear paraphrased rather than originally written. It is not a database comparison like Turnitin, but is useful for identifying risk areas and getting suggestions to improve originality.

Can students use this for academic work?

Yes. It is designed to help students identify passages that need rewriting before submitting assignments. Use it as a self-check tool to improve originality before final submission.

What does the originality score mean?

A score of 100 means the text appears fully original. 75–99 is low risk. 40–74 is medium risk (some sentences may need rewriting). Below 40 is high risk (significant rewriting recommended).
