Diff checker
Compares two blocks of text line by line and shows what was added, removed, or unchanged.
What is Diff checker?
Comparing two versions of text line-by-line to see exactly what changed is the basis of code review and document revision tracking — this does the same job as `git diff`, without needing a repository.
How to use it
Paste the original text on the left and the changed version on the right — added, removed, and unchanged lines are shown color-coded.
Example
"line two" changed to "line 2 changed" shows:
- line two (removed, red)
+ line 2 changed (added, green)
