Screen Annotation and Desktop Whiteboard for Mac
TrarrenShot Live Canvas is a screen annotation and desktop whiteboard overlay for Mac. It gives presenters, remote teams, developers, and designers a lightweight way to draw on screen during Zoom, Teams, screen sharing, product demos, design reviews, and support calls.
How It Works
Open Live Canvas
Use the Fn toggle to open the Live Canvas overlay without switching away from the app you are presenting.
Draw on screen
Use the annotation tools to circle, underline, point, or write directly over your live desktop.
Keep the meeting moving
Hide the canvas when you need to click through or continue using the apps underneath.
Capture the result
Copy, save, or share the marked-up screen when you want to preserve the explanation.
Live Canvas is most useful when the conversation depends on visual context: remote meetings, walkthroughs, support sessions, interface reviews, and live presentations.
For Zoom, Teams, and Remote Work
Use Live Canvas when a normal screenshot or separate whiteboard would interrupt the conversation. You can draw directly over the current desktop, explain the interface in context, then hide the canvas and keep using the apps underneath.
Privacy
Recognition, stitching, annotation, and export preparation run locally on your Mac.
