How it works
Compares left and right text word-by-word, highlighting removals in red and additions in green for quick copy-ready review.
- Toggle whitespace ignore to skip leading and trailing differences.
- Best for short to medium snippets; trim huge files for faster renders.
Quick examples
Word diff (tiny)
Left: hello world
Right: hello brave world
Added: brave | Removed: (none)
