  • Compare by line or by word
  • Ignore capitals and extra spaces
  • Line numbers for both versions

Frequently asked questions

What can I compare?

Any text: two drafts of an essay or contract, product descriptions, code, lists, CSV rows. Paste the original on the left and the new version on the right.

By line or by word — which should I use?

By line suits code, lists and data. By word suits normal writing, where a single changed word inside a long paragraph matters.

Is my text uploaded?

No. The comparison runs in your browser. Your text is remembered only in this browser so it's still there if you reload.

Is there a size limit?

It handles thousands of lines comfortably. For very large files, compare them in parts.
