Text Diff Checker

Compare two versions of text and inspect word-level additions and removals inline. Nothing is uploaded; your comparison stays in this browser.

Text to compare

Up to 50,000 characters in each version. Unchanged whitespace is preserved in the inline results.

How to compare text

Paste the original and updated text, then choose Compare. Removed words appear in the original pane; added words appear in the changed pane. Empty text is supported, so you can compare a passage to a blank version.
