- The browser demos are described as live-rendered scenes in the same board language the model writes, not prerecorded videos.
Field notes
The page lays out a three-step workflow: summon the overlay with Option–Shift–Space, mark an item, then speak or type a question. Its demos run in the browser and are described as scenes written in the same board language as the model and drawn by Ink Brain’s own engine, rather than prerecorded video. The download is listed for macOS 14 or later on Apple silicon and Intel; the page also links to source code, an MIT licence, and an install script.
