Text comparison is when you look at two or more pieces of writing to find what is the same and what is different. It helps people see if two texts have similar words, sentences, or ideas.
For example, if two students write about the same topic, text comparison can check if their writing is alike or different.
In a more detailed sense, text comparison is used to analyze texts to determine if parts have been copied, paraphrased, or even plagiarized. It can be helpful in education, research, and detecting duplicated content.
If you need a reliable definition of text comparison for your essay, here is one:

Text comparison has been an important task for a long time, used to find similarities or differences in written work. In the past, people had to do this manually by reading through two or more pieces of text and looking for matching words or phrases. This process was slow and could lead to mistakes, especially when there was a lot of text to compare.
Today, thanks to computers, text comparison is much faster and easier. People can use text comparison software and plagiarism detectors to quickly find copied or similar text. These tools work by scanning documents and pointing out any text that is the same or very similar. There are both commercial and free solutions available that help with this. These modern tools use smart programs to make text comparison much more accurate, saving time and helping to ensure that written work is original. Text comparison by software has made the process simpler and more reliable in today's world.
Text comparison is used in many different fields.
Education
Teachers use text comparison to check if students copied their work from books, the internet, or another student. This helps find plagiarism and makes sure students write in their own words. Students can also use text comparison to self-check their essays and reports before turning them in, helping them avoid accidental plagiarism. Many schools and universities use these tools to check papers before they are submitted to make sure the work is original. By using text comparison, both teachers and students can make sure writing is fair and follows the school rules.
Finding Duplicates
Businesses and self-employed individuals, like news website owners, bloggers, and online store owners, use text comparison to make sure their articles, product descriptions, and advertisements are unique. Experts who help websites appear in search results, called SEO specialists, use these tools to find and fix duplicate content because repeated text can lower a website’s ranking in search tools like Google, Bing, or Yahoo. Writers and publishers also use text comparison to check that their work is not accidentally repeated on different pages or websites. Keeping content original helps businesses get noticed online and provide fresh, valuable, and more unique information to their readers.
Laws and Rules
Lawyers and lawmakers compare legal documents to check for changes in contracts, agreements, or new laws. This helps them find mistakes, missing details, or unexpected changes that could cause problems. By carefully reviewing these documents, lawyers make sure everything is correct and follows the law before they are approved or signed.
Language and AI
Computer software uses text comparison to learn different ways of saying the same thing, even if the words or phrasing are different. This helps create tools like translation programs and chatbots that can understand people better. By comparing text, these programs make it easier for people to communicate with technology in different languages and styles.
Computer Programming
In computer programming, when programmers work on code, they compare it to see which parts were changed or updated. This helps them find mistakes, track how the code is evolving, fix any bad code, and make sure one programmer's changes don't affect another’s work. By comparing code, programmers can work together better, avoid mistakes, and make sure the final product works properly.
