Hi everyone! I'm Ian, the maker of Sketchover and the creator of ProAnima.
Explaining something on a shared screen often means pointing at tiny details or switching to a separate whiteboard. Sketchover lets you draw directly over the app you're showing, keeping the explanation in context.
You can add arrows, Markdown notes, screenshots, and a laser pointer. Hold Alt to click and scroll underneath while your annotations stay visible. You can also copy the drawing into chat or save it as a PNG that remains editable in Sketchover.
It's free and open source under Apache 2.0, for Windows, macOS, and Linux.
I'd love to hear how you'd use it—in teaching, code reviews, design feedback, or something else. What would make screen annotation more useful in your workflow?
Thanks for taking a look!
