Description
I built and released a Mac app I always wanted to exist:Glassboard let's you draw over anything on your Mac, across every app and every screen, Khan-academy style!Hold a keybind and draw. Release and it fades away. That's all! (well, except colors, shapes, a radial menu switcher and keybinds galore). But the basic concept is simple hold, draw, release, continue presenting without losing flow.Made for frequent screensharers and content creators.No more wiggling my mouse pointer at what I want to highlight while screensharing.Try it at https://stem.ps/glassboard. It's completely free and will stay that.

Could you build this?
Yes Transparent screen annotation apps for macOS are classic utility tools that can be implemented in Swift using standard NSWindow overlay levels, CGContext drawing, and global event monitors.

Same idea, different domain
Nobody's really built a content generation tool for Government yet.
