AI plagiarism checker
Traditional plagiarism checkers only compare text against published websites and journals. This AI plagiarism checker addresses modern generative writing by identifying content fabricated by language models without any preexisting web match.
It evaluates vocabulary entropy, sentence structure rhythm, and semantic predictability to identify AI-generated text, AI-paraphrased excerpts, and mixed human-AI collaborations.

Frequently asked questions
What is the difference between copy-paste plagiarism and AI plagiarism?
Copy-paste plagiarism duplicates existing human work found online. AI plagiarism involves generating entirely new text from a prompt; because it has no direct online duplicate, standard plagiarism engines miss it. Our tool detects synthetic AI generation directly.
Can students use this to self-check before submitting?
Yes, thousands of students check their own work to verify that their natural writing doesn't produce false positive signals due to overly formal wording.
