The Text Diff Tool, also known as a diff checker, is a powerful utility for comparing two blocks of text to find and highlight the differences between them. It is perfect for developers, editors, and writers who need to see what has changed between two versions of a document, code file, or article. The tool clearly marks added and removed characters, making it easy to spot modifications at a glance.

1. Paste the original version of your text into the "Original Text" box on the left.
2. Paste the modified or new version of your text into the "Changed Text" box on the right.
3. Click the "Compare Text" button.
4. A "Comparison Result" section will appear below, displaying the text with the differences highlighted. Text that was removed from the original will be struck through and have a red background, while new text added in the second version will have a green background.
