FAQ

Quick answers about privacy, accuracy, and best practices.

Does this search the whole internet?

No. It only checks for repeated sentences within your pasted text. For rewrite help, use the Paraphrasing Tool.

Is my text stored?

Your text is processed to compute the score and duplicates, then discarded. Nothing is indexed.

Why is my uniqueness score low?

You may have repeated sentences or many short lines. Raise the minimum length or paraphrase highlighted sentences.

Is this OK for homework or theses?

Yes—use it to polish your own writing. Always follow your school or publisher’s guidelines.
