Text Compare

Compare Two Texts Online — Free

Paste two versions of a text and instantly see exactly what changed — additions and removals highlighted clearly, word by word or line by line.

How to Compare Text

Paste your original text on one side and the changed version on the other. Choose whether to compare word-by-word or line-by-line, and whether to ignore differences in capitalization, then click "Compare Text." Added text is highlighted in green, removed text in red with a strikethrough.

Word Mode vs. Line Mode

Word-by-word comparison is best for prose — an essay, an email, a paragraph that's been lightly edited — since it pinpoints exactly which words changed inside a sentence. Line-by-line comparison suits structured content like code, lists, or configuration files, where entire lines are added, removed, or reordered rather than edited mid-sentence.

Good Uses for This Tool

Checking what changed between two drafts of a document, reviewing edits someone else made to your writing, comparing two versions of a contract or policy, or spotting differences between two similar blocks of code or text.

Is It Actually Private?

Yes. The comparison runs entirely in your browser — neither text is ever sent to a server.
