About the Text Diff Checker

Our Text Diff Checker (or "diff tool") is a powerful utility for comparing two pieces of text. It highlights the exact characters, words, and lines that have been added, removed, or changed between the original and the new text. This visual comparison makes it incredibly easy to spot differences that might be hard to find manually.

Who is this tool for?

  • Developers: Compare different versions of code to review changes, debug issues, or merge branches.
  • Writers & Editors: Track revisions in articles, essays, or manuscripts. See exactly what has been changed between drafts.
  • Legal Professionals: Compare contracts and legal documents to identify modifications and ensure accuracy.
  • Anyone: Anyone who needs to find the difference between two versions of a text file, from a simple shopping list to a complex report.

How it Works
