Text Diff Generator

Used by developers, writers, and creators worldwide.

A text diff generator compares two versions of a piece of text and shows you exactly what changed between them, line by line. Paste an original and a revised version, and it lists every line that was removed (marked with a minus) and every line that was added (marked with a plus), along with a quick summary count. Writers use it to review edits between drafts, developers to eyeball config changes, and teams to see what a collaborator altered. Spotting differences by eye is slow and error-prone; a clear diff makes changes obvious in seconds. The comparison works at the line level, so it is ideal for lists, notes, snippets, and any text broken into lines. Use it to confirm an edit, audit a change, or settle what moved between two versions.

FAQ

does it compare line by line or word by word

It compares at the line level, listing whole lines that were added or removed. This is ideal for lists, notes, snippets, and any text broken into lines. For prose in long paragraphs, split it into lines first for the clearest result.

is my text sent anywhere

No. The comparison runs entirely in your browser, so neither version is uploaded or stored. You can safely diff confidential or sensitive text.

what do the plus and minus marks mean

A minus marks a line present in the original but missing from the revised version (removed), and a plus marks a line present in the revised version but not the original (added). The summary at the top counts both.
