The Best Screen Annotation Tools for Teachers on Mac

Teachers using Mac for online lessons, recorded lectures or tutoring need a way to mark up the screen in real time: circling vocabulary, sketching diagrams, highlighting reading passages. A real annotation tool keeps students focused without breaking out of your existing slides or browser. Here are the best options on macOS.

How we picked

  • Works during Zoom, Google Meet and other screen shares
  • Annotations appear in screen recordings (QuickTime, Loom)
  • Easy to use mid-lesson without losing flow
  • Affordable for educators

Scribbble

Our pick

Modern Mac annotation app, made for live lessons

Scribbble draws on top of any Mac app: slides, PDFs, browsers, Zoom shares. The Highlighter is great for marking up readings; Spotlight dims everything except what you're explaining; Magnify zooms into small text or code so the back row can read it; Whiteboard mode gives you a blank canvas mid-lesson without opening another tab; the pen, arrow, rectangle, ellipse and text tools cover live diagramming. A built-in Snapshot tool captures the whole screen or a region, handy for saving a student's work or a lesson still. One-time license, free to try.

Pros

  • Highlighter, Spotlight (focus dim), Magnify (screen zoom) and Whiteboard mode built in
  • Multi-monitor support: annotate the display you're projecting or sharing

  • Shapes include arrow, rectangle and ellipse
  • Works in Zoom, Google Meet, recordings

#2

Presentify

Strong cursor highlighting for online classes

If your students often lose track of your cursor on a shared screen, Presentify's cursor highlight feature is the strongest in the category. Standard pen and shape tools alongside it.

  • Mac App Store

Cons

ZoomIt for Mac

Free, with built-in screen zoom

Microsoft's ZoomIt is now available on macOS. Its built-in screen zoom is genuinely useful for showing fine detail in slides or code to a large remote class, and it's free.

Best for

Teachers who want a fully free tool with a break timer

Pros

  • Free
  • Built-in zoom and break timer

Cons

  • UI is a Windows utility port
  • No spotlight or measure

#4

CleanShot X

For teachers focused on lesson recordings

If you spend more time recording lessons than presenting them live, CleanShot X is excellent. It captures, annotates and records all in one app.

Best for

Teachers building recorded lesson libraries

Pros

  • Screen recording with annotations
  • Cloud sharing

Cons

  • Limited live on-screen drawing
Pricing: One-time or SetappScribbble vs CleanShot X

Bottom line

For most teachers running live or recorded Mac-based lessons, Scribbble is the best balance of price, features and ease of use. The Highlighter and Spotlight tools in particular are a great fit for keeping students focused. If your specific challenge is cursor visibility, Presentify is worth a look. If you mainly record lessons rather than present live, CleanShot X may suit you better.

Annotating screenshots instead of your live screen?

Every app on this list draws on your live Mac screen. If what you actually need is to mark up a screenshot you've already taken, that's a different job. Use our free Mac screenshot annotation tool. Paste an image, add arrows, text, numbered steps or a blur to redact sensitive details, then copy the result straight back to your clipboard. It runs in the browser, so there's nothing to install and your image never leaves your device.

FAQ

Will my annotations show up when I record with QuickTime or Loom?

Yes. All the apps in this list (with the exception of CleanShot X's screenshot mode) draw at the OS level, so any screen recorder captures the annotations as part of the screen.

Can I use these apps in Zoom and Google Meet lessons?

Yes. Because the annotations are drawn on the actual screen, anything you share via Zoom, Meet, Webex or Teams will include them.

Are there discounts for educators?

Reach out to each developer directly. Many independent Mac app developers, including Scribbble, are willing to help teachers and schools with bulk licensing.
