About Paragraph Diff & Compare
Paragraph Diff & Compare treats each paragraph (a block of text separated by a blank line) as a single unit. Ideal for comparing long documents without being distracted by line wrapping.
Added, removed, or changed paragraphs are highlighted so you can focus on content changes rather than line-formatting differences.
FAQ
What is the difference between "diff" and "compare"?
Both are done by the same tool. "Diff" highlights the lines/parts that changed (added/removed), while "compare" shows how similar the two inputs are (similarity percentage + summary). You get both at once here.
Is my data sent to a server?
No. The entire comparison is computed in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
