How do I use the text diff tool?
Paste the original on the left and the edited text on the right, click Compare — differences highlight automatically: red for removed, green for added.
What do red and green mean?
Red marks content in the left but removed; green marks content added on the right. Spot changes instantly without line-by-line reading.
Does it support code comparison?
Yes. Line-based diff suits code versions, config changes and SQL edits, helping review whether modifications are correct.
Is online text comparison safe?
Safe. Comparison runs locally; text never uploads, suitable for unpublished code and documents.
Can it handle large text?
Yes, smooth up to ~1MB; split larger inputs for accurate results.
What is text diff best for?
Code review, document version proofing, config comparison, initial plagiarism checks and contract clause changes.
Are there limits on free use?
No. Free, no registration, unlimited.
Can I copy the result?
Yes — select and copy from the result area.
