Questions fréquentes
›Is my text sent to a server?
No — diffing happens entirely in your browser.
›Can it diff very long text?
Yes — anything your browser can hold in memory. Multi-page documents work fine.
›Does it ignore whitespace?
By default we count whitespace differences. Toggle 'ignore whitespace' to focus on real changes.
›Word-level or line-level diff?
Currently line-level. For word-by-word diff inside a line, paste a single line on each side.
›Is the diff checker free?
Yes — fully free, no signup.
