# Summarize a PDF, search it by meaning, or map it

> In the AI assistant, the **Summary** tab writes key points that link to their pages (2 credits), and **Search** finds passages by meaning (1 credit). For a visual overview, [PDF to mind map](https://pdfbetter.com/tools/pdf-to-mind-map/) builds a map whose nodes quote their pages.

- Counts toward: AI credits

## Summarize

1. **Open the Summary tab**: From the dashboard, click ✨ **AI assistant** → **Summarize a PDF**, or, with a document open in the editor, click the ✨ **AI assistant** button in the top bar and switch to the **Summary** tab.
2. **Pick a length**: Choose **Brief**, **Standard** or **Detailed**. Add a **Focus on** topic if you want, such as "payment terms and deadlines".
3. **Run it**: Click **Summarize**. Each key point links to the pages it comes from.
4. **Check what's missing**: Open **What this summary leaves out** to see topics it didn't cover. Click **Copy summary** to paste it elsewhere.

Points that couldn't be tied to a specific page are flagged so you can check them. Pages with no text layer, and pages past your plan's AI page cap, are listed as not read. The latest summary stays in the tab; **Summarize again** runs a new one.

## Search by meaning

The **Search** tab finds passages about an idea even when the wording differs. Type what you're looking for ("what happens if rent is late") and click **Search**. Results show each passage, its page and how closely it matches, plus how many exact matches your words have, for contrast. If nothing in the document is about it, it says so.

## Mind map

1. **Open the tool**: Go to [PDF to mind map](https://pdfbetter.com/tools/pdf-to-mind-map/) and click **Choose a PDF**.
2. **Set options**: Pick **Compact**, **Standard** or **Detailed**, and an optional **Focus**.
3. **Make it**: Click **Make mind map**. Every node's quote is checked word for word against its page; nodes that fail are removed and counted.
4. **Use it**: Click a node to see its verified quote and preview the page. **Export** saves PNG, SVG, PDF, Markdown or OPML, or click **Add as last page** to append it to the document.

A mind map costs 3 credits. One map reads only part of a very long document and says which pages it skipped; [split the PDF](https://help.pdfbetter.com/convert-organize/split-pdf-extract-pages/) to map the rest.

> **Heads up:** AI summaries can miss nuance. Use the page links to check anything you'll rely on, especially numbers, dates and obligations.

### Can I summarize several documents together?

Use a workspace and generate a **Brief**. It cites each document, version and page.

### Why did my summary skip pages?

They have no text layer ([run OCR](https://help.pdfbetter.com/editing/make-scanned-pdf-editable-ocr/)) or they're past your plan's page cap (100 pages on Free).
