Text Diff Checker
Compare two blocks of text and highlight every difference.
About This Tool
Paste two versions of a document, paragraph, or piece of code and instantly see exactly what changed between them — added words highlighted in green, removed words in red — line by line. Useful for comparing contract revisions, article edits, or code snippets without manually reading both versions side by side.
How to Use Text Diff Checker
- Paste the original text into the left box.
- Paste the changed text into the right box.
- Click "Compare" to see differences highlighted.
Frequently Asked Questions
Does it compare word by word or character by character?
The comparison works line by line and highlights changed words within each line, which is the most readable way to spot edits in prose or code.
