Text Compare
Compare two blocks of text and highlight what changed. Word-level diff.
What is the Text Compare?
The Text Compare tool diffs two blocks of text side by side: additions in green, removals in red, unchanged lines in neutral. Toggle "ignore whitespace" or "ignore case" to focus on meaningful changes only.
Useful for reviewing contract revisions, config file changes and manuscript edits — the diff runs in your browser, so neither text is uploaded.

Frequently asked questions
Does the tool detect moved paragraphs?
Moved content shows as a removal plus an addition — true move detection is not implemented.
Are my texts stored anywhere?
No — the diff runs in-browser and disappears when you close the tab.
