Text & Code Diff Checker

1. Paste or Upload: Add your original text in the left panel and modified text in the right panel. You can paste directly or upload text files.
2. Configure Options: Choose your view mode (side-by-side or inline), and toggle options like ignore whitespace or ignore case as needed.
3. Compare: Click the Compare button or enable auto-compare to see differences highlighted instantly.
4. Navigate Changes: Use the Previous/Next buttons to jump between differences, or scroll through the comparison view.
5. Export Results: Copy the unified diff output to share or save for later reference.

Our diff checker uses color coding to make changes easy to identify:

• Green (Additions): Lines or text that were added in the modified version
• Red (Deletions): Lines or text that were removed from the original version
• Yellow (Modifications): Lines that were changed, with character-level highlighting showing exactly what changed

The line numbers on the left help you track exactly where changes occurred in both versions. In side-by-side mode, you can see both versions aligned for easy comparison.
