Outcome: You’ll enable macOS’s built-in Summarize service so you can condense long text into quick, skimmable points in seconds.

Who this is for: Mac users who read long emails, articles, notes, or docs and want faster review without opening extra apps.

Time required: About 2 minutes.

Quick Answer

Enable Summarize in macOS Keyboard Shortcuts under Services > Text, then select text in an app and run Services > Summarize from the app menu or context menu.

What this trick does

macOS includes a native text summarizer service. Once enabled, you can select text in many apps and instantly generate a shorter version for quick reading. It’s ideal for previews before deciding whether to read the full piece.

Prerequisites

  • Mac running a modern macOS version (Ventura or newer recommended)
  • A text-based app (Safari, Notes, Mail, TextEdit, etc.)
  • Selected text (works on text, not images/screenshots)

Step-by-step: enable and use Summarize

  1. Open Keyboard Shortcuts.
    Go to System Settings > Keyboard > Keyboard Shortcuts.
    Expected result: You see shortcut categories including Services.
  2. Enable the Summarize service.
    Open Services, find the Text section, and enable Summarize.
    Expected result: Summarize appears as an available service and can be assigned a shortcut.
  3. (Optional) Assign a keyboard shortcut.
    Set a shortcut you’ll remember (for example, Control+Option+S if available).
    Expected result: The service can be triggered instantly without menu hunting.
  4. Use it on selected text.
    In Safari, Notes, Mail, or TextEdit, highlight a block of text, then choose App Menu > Services > Summarize (or right-click and look under Services).
    Expected result: A Summarize window opens with a condensed version you can review or copy.

Expected result checks

  • Setup check: Summarize is enabled in Services > Text.
  • Usage check: Summarize appears when text is selected in supported apps.
  • Outcome check: You can produce a shorter, readable summary of long passages in seconds.

Common mistakes

  • Trying to summarize text inside an image or screenshot (service needs selectable text).
  • Not selecting any text before opening Services.
  • Assigning a shortcut that conflicts with another app shortcut.

Troubleshooting

  • Summarize missing from Services: Re-check Keyboard Shortcuts > Services > Text and enable it, then restart the app you’re testing.
  • Menu item is grayed out: Ensure text is actively selected in a supported text field/document.
  • Shortcut does nothing: Pick a different unused shortcut and test again.
  • Summary quality feels weak: Try selecting a cleaner section (fewer tables/boilerplate) or summarize in smaller chunks.
