About Text Comparison
What is a Diff Checker?
A diff checker compares two pieces of text and highlights the differences between them. It shows which lines were added, removed, or modified — essential for code reviews, document versioning, and debugging configuration changes.
How to Compare Text Online
Paste your original text on the left and the modified version on the right, then click Compare. The tool shows a side-by-side view with red highlights for removed content and green for added content. Navigate between changes and merge them selectively.
Use Cases
Compare code before and after refactoring. Check what changed in a config file. Verify document edits. Compare API responses. Debug why two supposedly identical files behave differently.
