GPTCheck

GPTCheck is a handy tool for checking the originality of any piece of text by comparing it against content that already exists on Google. Whether you are reviewing an essay, a report, or AI-generated writing, it helps you quickly see how closely your text matches what can be found online.

Using it is simple: just highlight a sentence, right-click, and select GPTCheck to launch a search. There is no need to copy and paste text into a separate website, which makes the whole process fast and frictionless.

Once the search runs, GPTCheck identifies the most similar sentence among the top website results and gives you a similarity score based on cosine similarity. This gives you a concrete, measurable signal of how original your text really is.
