About Showmark: Modern Draw & Annotate on Any Web Page

Showmark is a modern annotation tool for presenting, demoing and screen sharing. Press one shortcut and draw rectangles, circles and freehand highlights on top of any web page, so everyone in the call sees exactly what you are pointing at. The page underneath is never modified, and your drawings disappear when you exit. WHY YOU'LL LIKE IT • A compact floating toolbar with a dark, translucent finish that stays out of the way of your content • Shapes un-draw themselves with a smooth animation a few seconds after you finish them, so you never clean up mid-demo • Keyboard-first: switch tools, colors and settings without hunting for buttons • Lightweight: nothing runs until you launch it, and nothing slows down your browsing • Private: drawings never leave your browser, and usage statistics can be switched off in one click FEATURES • Rectangles, circles and freehand strokes. Pick a tool with one key (R, C, F) or from the toolbar • Auto-erase after 2, 5 or 10 seconds, or keep shapes until you clear them • Six preset colors plus a custom color picker • Shift-drag for perfect squares and circles • Drag the toolbar anywhere or collapse it to a single dot; it remembers where you left it • Annotations stay attached toll • Remap every drawing shortcut and set your default color and auto-erase delay in Settings • Works on any website, in Chrome and other Chromium browsers HOW TO USE 1.
