# Text Diff Checker

> Compare two texts and highlight exactly what was added and removed.

To compare two texts, paste the original on the left and the changed version on the right. Additions are highlighted in green and removals in red, and you can compare by line, word or character depending on how fine-grained you need the diff.

## FAQ

### Why does my diff show a whole line changed for one character?

Because line-based diffing is the default — a line either matches or it does not. Word or character diffing shows the precise change, at the cost of being noisier on large edits.
