Paste the original and the revision; only the changes are highlighted. By line, word or character.
A counterparty sends back a contract with 'small changes'; an editor returns a draft; terms of service are updated; two versions of a config file. A changed number that is easy to miss by eye is obvious here.
Word points at the exact words that changed inside a sentence and suits contracts and prose. Line shows added and removed lines with line numbers and suits lists, code and tables. Character catches single-letter typos.
Ignores indentation and repeated spaces introduced by pasting, so only the wording counts. Turn it off for code where indentation matters.
Open the document, copy the body text and paste it. Text from tables may arrive cell by cell. HWP is a registered trademark of Hancom Inc.; Keepdesk is not affiliated with, sponsored by or endorsed by Hancom.
When reviewing updated terms or privacy notices, select Line mode to display numbered lines side by side. The addition and deletion counts let you quickly gauge the scope of the revision before reading each clause.
Comparing configuration files often flags indentation changes as false differences. Turn on Ignore Whitespace to filter out tab-versus-space noise and focus on actual value modifications.
Use the default Word mode to isolate replaced terms and expressions between a rough translation and its final proofread. Switch to Character mode when you need to catch spelling corrections, punctuation edits, or spacing adjustments at the letter level.
Screens and numbers from actually running this tool with sample values (2026-10-06, Chromium-based browser on a Mac). Results vary with your input and device.

Two versions of a sample contract were compared word by word. The result marks 11 additions and 3 deletions, with changes highlighted in color.
The contract end year changed from 2027 to 2028, monthly rent from 1,200,000 won to 1,250,000 won, and the deposit return period from 30 days to 14 days.
Nowhere. The comparison runs in your browser, and the last input is kept only in this browser.
Tens of thousands of characters are fine. Very long inputs fall back to line mode automatically.
Usually different line endings (Windows vs. Mac) or full-width spaces. Try 'Ignore whitespace'.
Yes, in addition to the default word comparison, you can view diffs by line (with line numbers) or by individual character.
Yes, toggling the 'ignore whitespace' option excludes differences caused solely by spaces or indentation.
No, direct file uploads are not supported; you should copy the text from your documents and paste it into the comparison fields.
Yes, you can click the swap button to instantly exchange the contents of the two text inputs.
