Capture, annotate, and share in seconds

Drag to snip any part of your screen, mark it up with a full annotation toolkit, and copy or share — without leaving your workflow.

Requires macOS 13 Ventura or later · Apple Silicon & Intel

The built-in macOS screenshot tool captures images but gives you almost nothing for annotation. Synapse's screen snip captures any region and opens it instantly in a full editor — draw with a pen, highlight in color, add arrows pointing to what matters, drop in numbered stamps, and add text callouts. When you're done, copy or share with one click.
