Text comparison tools work by looking at two or more pieces of writing and checking how similar or different they are. These tools scan the text to find matching words, sentences, or ideas.
For example, if two students write about the same topic, a text comparison tool can highlight which parts are the same and which are different.
Some tools use smart technology to detect small changes, like when a sentence is rewritten using different words but keeps the same meaning. They can also help teachers check if students copied from each other or from the internet.
