The Text Diff Checker compares an original and a changed version of any text and highlights every difference line by line, so you can spot edits, additions, and deletions at a glance.
What is a Text Diff Checker?
A text diff checker compares two versions of a piece of text and shows you exactly what changed between them. Added lines are highlighted in green, removed lines in red, and unchanged lines stay neutral — the same approach used by version control systems like Git.
Paste your original text on the left and the changed text on the right. The tool computes the differences instantly in your browser and renders a clear line-by-line comparison with running totals of additions and deletions.
Common Uses
- Writers and editors comparing two drafts of an article or document
- Developers reviewing changes between two snippets of code or configuration
- Students and teachers checking edits between submissions
- Anyone verifying what changed between two versions of terms, contracts, or notes
