How to Use
Paste the two versions into the left and right input panels and click Compare to see added, removed, and unchanged lines.
When comparing code or config, paste it as-is rather than reformatting first, so formatting noise does not hide real changes.
Copy the prefixed diff result to share with teammates. Everything is processed in the current browser, so sensitive content is safe.

FAQ
Is it better for code or for plain text?
Both. If you need a line-by-line comparison, this tool fits the task.
Will the compared content be saved anywhere?
No. Inputs and results are handled in the current browser only.
