Glassboard – Draw over everything on your Mac, Khan-academy style
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.

Hold a shortcut to draw freehand lines and shapes over whatever you
Glassboard lets you scribble over anything on your Mac. Hold a shortcut to draw, release and your ink fades away — perfect for demos, screen shares, and teaching. An annotation layer that's only ever one key press away — and out of your way otherwise. Hold a global shortcut and drag to draw over anything on screen — slides, demos, code, the desktop. Temporary by design. Your strokes disappear, once you let go. Pink, lime, yellow, turquoise, and orange — Make your message stand out. Freehand pen, arrow, rectangle, and ellipse, with adjustable thickness. Glassboard draws on a transparent overlay across apps on every display, without stealing focus from the app underneath.

I'm happy to announce we've finally released our 2nd macOS app, Draw Over It, a tiny desktop app that enables drawing, highlighting, or annotating directly on top of anything on your Mac. I've always wanted something like this for instant and unobtrusive sketching and annotation for pair programming and demos. I always found the standard web-based diagram and drawing tools a bit too cumbersome. So we built a simple overlay that could appear over any window or app with one shortcut. It doesn't collect any user data and doesn't require any system permissions - it's sandboxed. It all…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
