Local extract, optional AI-powered summary, then download in the format you need. Privacy-first by design.

How to summarize a document with AI

  1. Open your file: PDF, Office, image, or text. Extract runs in the browser. Scans and images can use local OCR.
  2. Choose mode and opt in: Pick executive, bullets, or by-section. Preview the text and consent to the AI-powered request.
  3. Export the summary: Download as PDF, Markdown, text, or HTML after the AI-powered summary is ready.

Frequently asked questions

Is Summarize AI-powered?

Yes. Summaries use optional Workers AI after a local extract. You control the text payload and can export the result.

Yes. Export to PDF, Markdown, text, or HTML and keep the file on your device.

Does summarizing upload my PDF?

No. Processing starts with on-device extract. The AI-powered step receives text only, never the PDF bytes.
