Uses AI in the cloud. The text of your PDF is sent to our AI provider (Anthropic) to write the summary; it is not stored. If your PDF is a scan with no text, it is first sent to our own server for OCR (sandboxed, deleted immediately) so there is text to summarize. Every other Ream tool runs on your device — this one does not.
Summarize PDF reads a long document and gives you the gist — a one-line TL;DR and the key points — so you don’t have to wade through every page. It’s built for reports, papers, contracts and anything you need the essence of, fast.
Please note — this is our one tool that uses AI in the cloud. To write the summary, the text of your PDF is sent to our AI provider (Anthropic) after you tick a consent box. It is processed and returned, not stored. This is different from every other tool on Ream, which runs entirely on your device — so please don’t use it for text you can’t share with a third-party AI service. It’s free, with no account and no watermark.
How it works
Your PDF’s text is extracted in your browser. When you confirm, that text is sent over an encrypted connection to the AI provider, which returns a summary that appears on the page. Nothing is kept afterwards. If your PDF is a scan with no text, Ream first runs it through OCR on our own server to create a text layer, then summarizes — so scans work too, with no extra step.
How to Summarize PDF
Add your PDF
Drop the file onto the box above or click to browse. The text is read in your browser.
Agree & choose a length
Tick the consent box (the text is sent to the AI provider) and pick Short or Detailed.
Read the summary
The AI summary appears on the page — copy it or download it as a text file.
The one tool that isn’t on-device — and why that’s clear
Ream’s promise is that your files stay on your device. Summarizing genuinely needs a large AI model, which can’t run in your browser at good quality — so this tool, and only this tool, sends text to a cloud provider. We make that explicit: it never happens without your tick, only the text is sent (not the file), it’s not stored, and our provider (Anthropic) is named in our Privacy Policy. If a document is too sensitive to share with a third-party service, use the on-device tools instead.
What it’s good for
- Getting the key points of a long report or paper before you read it.
- A quick TL;DR of a contract, policy or set of terms.
- Deciding whether a document is worth reading in full.
- Turning a dense page into plain bullet points.
Choose Short for a fast overview or Detailed for a structured, sectioned summary.
Good to know
- Scanned PDFs are handled for you — Ream runs OCR automatically first, then summarizes. Only a very low-quality scan might still be unreadable.
- Very long documents are trimmed to a sensible length before summarizing.
- AI can occasionally miss nuance — for anything important, treat the summary as a starting point, not a replacement for reading.
- There’s a fair-use hourly limit to keep the free service running.

Frequently asked questions
Does this tool send my document somewhere?
Yes — unlike our other tools, Summarize sends the PDF’s text to our AI provider (Anthropic) after you tick the consent box, so it can write the summary. Only the text is sent, and it is not stored.
Is it private?
The other 40-plus Ream tools run entirely on your device. This one does not — it uses a cloud AI. Don’t use it for text you can’t share with a third-party service.
Which AI does it use?
Anthropic’s Claude, named as a sub-processor in our Privacy Policy. Your text is not used to train it.
Does it work on scanned PDFs?
Yes. If your PDF is a scan with no text layer, Ream automatically runs OCR first (on our own server, free) and then summarizes. Only a very low-quality scan might still be unreadable.
Can I trust the summary?
It’s a helpful overview, but AI can miss nuance. For anything important, use it as a starting point, not a substitute for reading.
Is it free?
Yes — free and no watermark, with a fair-use hourly limit.
