Text Diff is a free, private text comparison tool that runs entirely in your web browser. Paste two blocks of text into the Original and Changed boxes, click Compare, and every addition and deletion is highlighted instantly. Because everything happens locally on your device, your content is never uploaded to a server. There is no sign-up, no installation, and it keeps working offline. It is useful for comparing code, documents, config files, essays, or any plain text.
