A native Mac app for computer-use models. The core idea was simple: what if you could control your computer with a copilot, locally?
I built Cuaview as a native harness around Claude Opus 4.5 to see what a strong computer-use model could do one-shot on real tasks. Through that loop it could play League of Legends badly but coherently, play Minecraft, book flights and hotels pretty well if you asked nicely, and do taxes end-to-end.
One of the more interesting runs was TFT. Claude played for two games and improved in-context from 0 to 3/30 rounds won. It figured out 3-starring on its own, which is a core mechanic of the game and was never explained to it.
I also redesigned the UI around what the model was actually doing. When computer-use tools get good enough, there should be less reliance on knowing what is in your dock and more emphasis on what actions are taking place and what the model is thinking. Cuaview highlighted actions in orange and kept the reasoning trace visible so the system stayed legible while it clicked around your machine.
