Vérificateur de Différence de Texte
Spot differences between two versions of a text easily. Ideal for writers, editors, and developers.
Advanced Text Difference Checker Tool for Precise Comparisons
Our Text Difference Checker (also known as a 'diff tool') provides a precise way to identify changes between two versions of text. Whether you're reviewing document revisions, comparing code snippets, or analyzing content changes, this tool visually highlights additions, deletions, and modifications to make differences immediately apparent.
How Our Text Diff Tool Works
Our tool employs the industry-standard Diff Match Patch algorithm to intelligently identify and display text differences. It offers two convenient viewing modes:
Unified View
This traditional view shows all changes in a single document, with clear highlighting:
- Added content: Text that appears in the second sample but not in the first (highlighted in green)
- Removed content: Text that appears in the first sample but not in the second (highlighted in red with strikethrough)
- Unchanged content: Text that remains identical between both samples
Side-by-Side View
This view presents both original and modified texts in parallel columns:
- Clear comparison: Original text on the left, modified text on the right
- Highlighted differences: Changes are still color-coded for easy identification
- Better for longer texts: Ideal for documents where context is important
Practical Use Cases for Text Difference Checking
