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
The tool uses a well-established algorithm to find the differences between the two text inputs.
The original and new texts are displayed next to each other for easy comparison.
Additions are shown in green and deletions in red for immediate visual feedback.
