Is this a plagiarism detector?

It only finds repeated word sequences. It cannot prove intent and is not a substitute for institutional tools.

Highlighted check text

Matches highlighted in amber.

Example input/output

Illustrative sample — your real inputs may look different.

Example input

Source + submission texts with overlapping 4-word streak

Example output
