Tool details and privacy
Paste two versions of a text to see what was added and what was removed, word by word or line by line.
Text removed from the original is shown in red with a line through it, and text added in the changed version is shown in green. The ignore options do not alter your text; they only decide what counts as a difference.
Options
- Compare by words or by lines.
- Ignore differences in spacing.
- Ignore Arabic diacritics.
- Ignore English letter case.
- Copying marks removed text as [-text-] and added text as {+text+}.
Limits
- 20,000 characters for each text.
- Comparing by words stops at about 4,000 words per text. Past that, compare by lines.
- When the texts differ in more than 2,500 places, the differing part is shown as removed, then added, in one block.

The comparison runs in your browser. Neither text is sent to our server or stored.
Questions
How do I compare two texts to find the differences?
Paste the original into the first box and the changed version into the second. Removed words appear in red and added words in green straight away.
Can I compare two versions of a contract or a document?
Yes. Copy the text of each version from Word or a PDF and paste it in. For long documents, compare by lines.
Are my texts stored or sent to a server?
No. The comparison happens only in your browser, and the texts are gone when you close the page.
What is the difference between comparing by words and by lines?
By words, you see each changed word inside a line. By lines, a whole line counts as different if anything in it changed, which suits lists and long texts.
