Text Diff
Compare two texts line by line and see what was added or removed. Your text stays in your browser and is never uploaded.
Enter text in both boxes to compare.
How to use
- Paste the original text on the left.
- Paste the changed text on the right.
- Review added (+) and removed (-) lines.
Notes and limitations
- Comparison is line by line, not word by word.
- Very large inputs are refused (product of line counts above 4,000,000) to protect browser memory.
- Whitespace differences count as changes.
