Compare two documents side by side
Drop or pick two documents: PDF, Word (.docx), OpenDocument (.odt), plain text (.txt) or Markdown (.md), draft vs signed, bundle v1 vs v2, HO letter vs earlier version. For two PDFs the tool hashes every page, runs a word-level diff on the changed ones, and can render a pixel heat-map; tick Compare text only to ignore page breaks. Word / ODT / text / Markdown have no fixed pages, so they're always compared as whole-document text. You can also mix formats (e.g. a .docx against its exported .pdf). Everything runs locally in the browser; files never leave the machine.
