Frequently asked questions
Which comparison mode should I use?
Lines suits code, CSV and lists; words suits contracts and articles; characters is best for short strings such as names or IDs.
Can it ignore case or spacing?
Yes — tick “Ignore case”, and in line mode “Ignore whitespace” to skip indentation and trailing spaces.
Is my text uploaded?
No. The comparison runs in your browser, so confidential documents stay private.
