About this tool

Paste two versions of a text to see exactly which words were added, removed, or kept the same — useful for reviewing edits, comparing drafts, or spotting changes between two versions of a document.

The comparison runs entirely in your browser; neither text is uploaded anywhere.

Frequently asked questions

Is this a word-level or character-level comparison?
Word-level — the text is split on whitespace and compared word by word, which is generally more readable than a character-by-character diff for prose.
Does word order matter?
Yes — the comparison finds the longest matching sequence of words in order, so moved text may show as a removal in one place and an addition in another.
Does it ignore capitalization or punctuation differences?
No — the comparison is exact, so "Hello" and "hello" are treated as different words.
