I’ve been working on a small proof-of-concept screen-recording tool that runs entirely in the browser. It lets you capture screens or windows, add a talking-head camera feed, layer multiple targets, drag and scale them, draw annotations directly on the canvas, and record everything to a local MP4/WebM file. There’s no backend, no build step, and no external dependencies apart from MediaPipe and Scrawl-canvas.

The project is intended to be hackable rather than polished, and includes a keyboard-accessible UI and a step-by-step walkthrough. Code and demo are here:

Feedback very welcome.
