Chat with your PDF, privately

Ask questions in natural language about any PDF and get cited answers. Powered by Claude. Text extracted in your browser, only relevant snippets ever leave.

How this stays private

  • Your PDF is read in your browser using pdf.js. The file itself never uploads.
  • Per question, only the most relevant pages (max ~30 KB of text) are sent to Claude.
  • Anthropic does not train on data sent via the API.
  • Open DevTools → Network and watch, only `/api/ai/chat` calls go out, with text payloads only.
