Summarize PDF with AI

About this tool

Summarize PDF with AI — Key Points and Answers Without Uploading

Get key points, a TL;DR or a headline for a PDF and ask questions about it, with the page each answer comes from. The AI built into your browser does the work, so the file is never uploaded.

Key Points, TL;DR or Headline

Switch between a bulleted list of key points, a short paragraph and a one-line headline. Long documents are summarised part by part first, so even a report of hundreds of pages fits.

Answers With Page Numbers

Ask a question and the passages that match it are found locally and handed to the model. Each answer names its pages, and a click opens the PDF viewer at that page.

On-Device AI Only

It uses the model built into Google Chrome (Gemini Nano). There is no fallback to an online AI service: where the browser has no built-in model, the page says what is needed.

How to use it

  1. Open the page in Google Chrome 138 or newer on a computer and drop your PDF.
  2. Choose Key points, TL;DR or Headline and click Summarize. The first time, Chrome downloads its AI model once.
  3. Scanned pages without text can be read with OCR first, right on the page.
  4. Type a question and click Ask. The answer streams in with the pages it is based on.
  5. Click a page number to check the passage in the PDF viewer.

Frequently asked questions

Is my PDF uploaded to an AI service?

No. The text is read from the PDF in your browser tab and summarised by the AI model that Chrome runs on your computer. Toolula sends neither the file nor its text anywhere.

Which browsers are supported?

Google Chrome 138 or newer on Windows 10 or 11, macOS 13 or newer, Linux or a Chromebook Plus, with at least 22 GB of free disk space and either a graphics card with more than 4 GB of memory or 16 GB of RAM. Phones, tablets and other browsers don't offer the built-in model to websites yet. Answering questions also needs Chrome's Prompt API.

In which languages does it write?

In the language of the page where the built-in model supports it, otherwise in English with a notice. The PDF itself can be in any language the model reads.

Can the summary be wrong?

Yes. A small on-device model can miss or misread details, so the answers name their pages: check the important ones in the viewer.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
