Frequently Asked Questions

Is this a professional plagiarism checker?

No. This is a **basic similarity checker**, not a professional plagiarism detection tool. It only compares the two texts you provide. It does not check against online sources, academic papers, or any other external databases. It is useful for finding direct copy-paste instances between two documents.

How is the similarity percentage calculated?

The tool breaks down the source text into unique phrases. It then checks how many of those phrases are present in the second text. The percentage is based on the ratio of matched phrases to the total phrases in the source text.

Is my text saved or stored anywhere?

Absolutely not. This tool runs entirely in your web browser (client-side). Your text is never sent to our servers, ensuring your data remains private and secure.
