Question 2

What does a text diff checker do?

Accepted Answer

A diff checker compares two versions of text and highlights what has changed between them. It shows additions (new text), deletions (removed text), and unchanged text. This is the same technique used by version control systems like Git to show code changes.

Question 3

Can I compare two versions of a document?

Accepted Answer

Yes. Paste the old version in the left box and the new version in the right. The diff view highlights every change. This is useful for proofreading, comparing contract revisions, checking content edits, or reviewing code changes.

Question 4

Is my text saved when using the diff checker?

Accepted Answer

No. All comparison happens locally in your browser. Neither version of your text is transmitted to our servers or stored anywhere. The comparison is performed entirely in JavaScript in your browser.

Question 5

What is the difference between character diff and word diff?

Accepted Answer

A character diff shows every individual character that changed, which can be hard to read. A word diff treats each word as a unit and shows which whole words were added or removed, making changes much easier to read. This tool uses word-level diff by default, with a line-level option available.
