DevTools / Diff

Text Compare & Merge

Paste two blocks of text to see the differences and selectively merge changes.

How does Text Compare work?

This tool utilizes a line-by-line diff algorithm to calculate the exact insertions and deletions between two bodies of text. It highlights removed lines in red and added lines in green, mimicking popular version control tools like Git.

How do I merge changes?

When differences are detected, you will see an "Interactive Diff" view. For any block of text that has changed, you will be presented with a prompt to either Keep Original or Accept Modified. Your choices instantly construct the final document in the "Final Merged Result" block below.
