Frequently asked questions
Will Diff Checker work offline?
Yes — once the page loads, processing happens locally with no further network calls.
Can Diff Checker handle non-English text?
Yes — it uses Unicode-standard rules that work for most major scripts.
Does Diff Checker save my text?
No. Diff Checker processes everything in your browser; nothing is uploaded or stored.
Is there a length limit?
Practically, several MB of text. Beyond that the browser starts to lag.
