Summaries turn long sources into navigable outlines. They're not single paragraphs; they're structured so you can drill into the bits that matter.
Generate a summary
- Open a page.
- In the AI Features panel, click the gear icon on the Summary tile to open settings (or click the tile to use defaults).
- Pick the sources to include - by default, every source attached to the page is selected. Untick any you want to skip.
- Pick a length:
- Brief (~300 words) - overview
- Standard (~600 words) - study notes
- Detailed (~1,200 words) - chapter-by-chapter
- Custom - type any word count between 50 and 3,000
- Click Generate. You can keep working in the page while it runs.
Narrowing to part of a source
Each source in the settings panel has a range editor. For a PDF you can specify start/end pages; for a video, a start/end timestamp. Set a range once and use Apply ranges to all to push the same scoping to every selected source.
Multi-source summaries
If the page has several sources (e.g. all the readings for one essay), leaving All sources selected produces a single summary that draws on every source you've ticked - useful for revision when you want one document instead of one per source.
Regenerating and editing
Once generated, the summary opens as an editable note. You can:
- Edit text directly in the block editor
- Click Regenerate to redraft with the same settings, or open settings to change length/scope first
- Rename the generation from the header pencil icon
Past generations stay listed in the Summary tile so you can flip between them or delete the ones you don't need.
Tips
- For a long PDF, generate a Brief summary first to see the structure, then drop into a Detailed one for the chapters you want to study closely.
- A Custom length over 3,000 words isn't allowed - use Chat for longer responses instead.
- Summaries share the same source index as chat, so cleaning up a transcript or removing an irrelevant source improves the summary too.
