Plagiarism Checker FAQs
Does this check against the internet?
No — this tool works locally in your browser and checks for internal text patterns, repeated phrases, and similarity between two documents you provide. It does not search Google, academic databases, or any external source.
What does the originality score mean?
The originality score reflects how varied and unique your writing is based on phrase repetition, common phrase usage, and vocabulary diversity. A higher score means more original writing.
When should I use the two-text comparison?
Use it to compare your draft against a source text to see how similar they are, or to compare a student submission against a reference document.
