Compare two drafts word by word instead of line by line

The job

Someone edits one clause of a paragraph and sends it back. A line-oriented diff paints the whole paragraph as changed on both sides; you still have to hunt for the actual edit. Word-level diff marks only the added and removed words.

Worked example

Original: "The delivery is scheduled for next Tuesday." Revision: "The delivery is scheduled for next Thursday." A line diff shows the whole line removed and re-added; the word diff highlights just "Tuesday" removed and "Thursday" added.

Paste both versions into the tool and run it. Removed words show in one color, additions in another, and a count summary reports how many words were added, removed, and left alone.

• Whitespace changes count as edits, so " , "→", " also shows — useful when punctuation spacing matters.
• Texts up to 100,000 characters per side. Fully rewritten long documents can take a moment because every token pair is compared.

When to use the line diff instead

For code, config files, and lists, line granularity is usually what you want — the Text Compare tool does that. Word diff is for prose: contracts, emails, essays, translated text, where edits happen inside lines rather than whole-line rewrites.
