Paste two versions of text or code and see a line-by-line diff: additions in green, removals in red, with a running count of changes.
How it works
- Paste the original text into the left pane.
- Paste the modified text into the right pane.
- The engine immediately highlights deletions in red and additions in green.
Frequently asked questions
Is this comparison line-level or character-level?
It is line-level, which is ideal for programming code and structured text files. Entire lines are flagged as added or removed.
Can I use this to compare complex code?
Yes. It works on any plain text. Changes in indentation and content will accurately register as line differences.
Does my proprietary code leave my browser?
No. The Longest-Common-Subsequence comparison algorithm executes entirely locally.
