Presentify is a screen annotation and presentation assistance tool designed specifically for macOS. It allows users to draw, highlight, and annotate in real time anywhere on the screen, and integrates practical features such as a timer and sticky notes, greatly improving communication efficiency and expressiveness in online teaching, video conferencing, product demos, and screen recording walkthroughs.
I. Detailed Explanation of the Core Interface and Workspace
After launching Presentify, its icon will appear in the menu bar. Click the icon or use the global shortcut to bring up the main control panel and annotation toolbar.

- Color and Thickness Selector: Click the color circle or stroke thickness icon in the toolbar to adjust.
- Menu Bar Status Icon: Displays the current mode (such as whether annotation is active) and provides quick access to settings.
1.2 Preferences Window (Open via Menu Bar Icon > Preferences)

II. Complete Workflow: From Start to Finish
Method 1: Click the Presentify icon in the menu bar and select Start Annotating.
Method 2: Use the default shortcut Control + Option + A (can be changed in settings).
After activation, a semi-transparent toolbar will appear at the top center of the screen, and a default drawing tool prompt will appear next to the mouse pointer, indicating that annotation mode is active.
After activation, simply drag on the screen with your mouse or trackpad to draw. To switch tools:
- Click the toolbar icons: Directly select pen, arrow, rectangle, ellipse, text, highlight, eraser, etc.
- Use shortcuts (while activated):

B - Arrow:
Shift + A - Rectangle:
R - Ellipse:

T - Highlight:
H - Eraser:
E - Move/Select:
V

While drawing, hold the Shift key to draw horizontal/vertical lines or perfect circles/squares. Hold the Option key to draw shapes from the center.
Before drawing or after selecting an existing annotation (use the Move tool V to click the annotation), you can make the following adjustments:
- Change color: Click the color circle in the toolbar, or use shortcuts
1,2,3, etc. to quickly switch between preset colors. - Adjust thickness/opacity: Click the stroke icon in the toolbar, or use
[and]to adjust thickness, and-and=to adjust opacity. - Fill shapes: After selecting a shape, click the fill icon in the toolbar.

III. Advanced Tips for Common Features
Tip 1: Quick Color Switching and Customization
In addition to using preset colors, you can customize tool color presets in Appearance or Tools under Preferences. While annotating, use the number keys 1-9 to instantly switch between the first 9 preset colors.
Tip 2: Precise Alignment and Movement
After selecting one or more annotations with the Move tool (V) (hold Shift to multi-select), besides dragging, you can use the keyboard arrow keys for pixel-level fine-tuning. Hold Command while dragging to make a temporary copy.
Tip 3: Presenter Cues and Timer Integration
Combine the timer with the sticky note feature. For example, set a 10-minute countdown and list your talking points in a sticky note. Place them at the edge of the screen, visible only to yourself, for seamless prompting.
Tip 4: Set Independent Configurations for Specific Apps
In the Apps section of Preferences, you can configure different default tools, colors, and shortcuts for different applications (such as Keynote, Zoom), enabling context-aware intelligent switching.
IV. Common Issues and Solutions
Issue 1: Keyboard shortcuts not responding
Solution: First, check System Settings > Keyboard > Keyboard Shortcuts > Accessibility to ensure there are no conflicts. Then check the Shortcuts tab in Presentify’s preferences to confirm the shortcuts are correctly set and not disabled.
Issue 2: Annotations not showing during screen recording or sharing
Solution: Make sure your screen sharing or recording software (e.g., QuickTime, OBS, Zoom) is capturing the “entire screen” rather than a “single window.” Presentify’s annotation layer sits at the topmost level of the system and will be included in full-screen captures.
Issue 3: Toolbar unexpectedly disappears
Solution: Press the activation shortcut Control + Option + A to turn off and then re-enable annotation mode. If the issue persists, check the menu bar icon > Preferences > Appearance and make sure the “Show toolbar” option is checked.
Issue 4: Mouse pointer obstructs the view during annotation
Solution: Go to Preferences > Appearance > Cursor to change the pointer style during annotation, for example, set it to a small dot or hide it entirely.
