Reference

PrivacyComparison runs in your browser — nothing is uploaded. Drafts stay local until you Clear.
WhitespaceIgnore whitespace when reformatting is noise. Keep it on for Python, YAML, and Markdown.
MarkersRed = removed, green = added, yellow tint = modified line with word highlights — all in the editors.
PatchCopy patch exports a git-style unified diff of the Original and Changed texts.
