Know where your files go.

superPDF works on your PDFs in this browser tab. Nothing is uploaded, and there’s no account. Only two features send anything about your documents out, and only when you use them: chatting with your own AI key, and share links (coming soon).

  • AI on your computer. Chat and summaries can run on your own device after a one-time download. Nothing is sent anywhere.
  • Or your own AI key. Your question and the document’s text (all of it for shorter documents, the relevant parts of longer ones) go straight to the provider you chose.
  • Private share links (coming soon). Files are encrypted before they leave. Only people with the link can open them; we can’t.
  • Saved documents are encrypted. So is your AI key, in this browser.
  • No analytics cookies. Usage counts are anonymous and never include file names or contents.
