See exactly what changed between two pieces of text.
Result
Start typing and the result appears here. No button needed.
Word diff, without the extra steps.
Compare two versions of a paragraph and highlight added and removed words. Both inputs remain on this page, and the result can be copied as a plain-text comparison.
How to use this tool
- 1Paste the original text.
- 2Paste the revised version.
- 3Compare to see removed and added passages.
When Word diff is the right tool
- An edited draft came back and you need to see what actually changed.
- Two versions of a clause or paragraph must be compared before signing.
- A copied block of configuration differs from the original in some way.
- You want a change review without uploading either version anywhere.
Word-level comparison
The comparison works on word boundaries rather than individual characters. Rewriting a sentence therefore shows as a coherent block of removed and added words instead of a scatter of single-letter changes, which is far easier to read. The trade-off is that a one-character typo fix marks the whole word as changed, which is usually the more useful behaviour anyway.
What counts as a difference
Whitespace and capitalisation differences are real differences: "Total" and "total" do not match, and a double space is not a single space. This is deliberate, because in contracts and configuration those distinctions matter. Very large inputs are capped to keep the comparison responsive in the browser, so compare the relevant sections rather than two entire books.
A few quick answers.
Paste the original text. Paste the revised version. Compare to see removed and added passages.
Tool inputs are processed in your browser. Crate has no upload endpoint and no accounts. Downloaded site assets and a cookie-free page-view count still require a connection; your files and text are not included in those requests.
Inputs are limited to 20,000 characters each to keep comparisons responsive. Word-level comparison is intended for prose, not semantic source-code analysis.
The comparison works at word level, which keeps rewritten sentences readable instead of showing a scatter of single-character edits.
Yes, deliberately. In contracts and configuration those distinctions carry meaning, so they are reported rather than ignored.
