Text compare
Two drafts of an essay, email or contract in, every changed word out. Switch the granularity to Words for prose and read the edits in place.
Guide
How to use it
- Paste the earlier draft on the left, the later one on the right.
- Switch granularity to Words, the right unit for prose.
- Read the inline view like tracked changes: struck-through red was cut, green was added.
- For a paragraph-by-paragraph overview instead, switch back to Lines.
Examples
Worked examples
A supervisor returns your draft "with a few tweaks" and no tracked changes. Paste both versions and every tweak surfaces, including the deleted paragraph you liked.
Version 3 of an agreement arrives. Comparing against version 2 shows "within 30 days" became "within 60 days" in the payment clause, one word block, easily missed by eye.
The website copy does not match the approved text. Paste both: two sentences were trimmed by someone in the CMS. Now you know what to restore.
Method
How it works
Both texts are split into words (line breaks preserved) and aligned with a longest-common-subsequence diff. Words outside the common sequence are marked added or removed and shown in place, so the result reads like tracked changes without anyone's account or upload.
Comparison happens on your device. For contracts and unpublished writing, that is not a nicety, it is the requirement.
FAQ
Frequently asked questions
How do I compare two versions of a document?
Paste the earlier version on the left and the later one on the right. Word granularity highlights each changed word: green added, struck-through red removed.
Can I compare two Word documents?
Select all in each document and paste the text here. Formatting is not compared, only the words, which is usually what the argument is about.
Is this safe for contracts?
Yes, and that is the reason to prefer it over upload-based comparison sites: both versions stay on your device. For a contract, also read the changed clauses in full, not just the highlights.
Why does a moved paragraph show as removed and added?
A sequence diff sees a move as a deletion in one place and an insertion in another. The words match, the positions do not. Treat matching red and green blocks as a probable move.
Does it catch punctuation-only changes?
Yes. A word with different punctuation attached is a different token, so a changed comma or full stop flags the word it touches.
What is the difference from the main diff checker?
Same engine, different defaults: this page is set up for word-level prose comparison, while the main page defaults to line mode for structured text.
