Not a video — the real widget, floating on a Mac just like he does on yours. Drag him anywhere, hover to slide out his control rail, then talk, type, or open his panel. His voice is his real on-device voice.

Cosmo's voice = Kokoro, on-device
Idea: a tiny desktop buddy ✨
Ask Cosmo to look something up — his sources land here.
Your voice never leaves your Mac on the local setting.
drag Cosmo · hover for controls
real on-device Kokoro voices
Every mood & reaction
Real eyes, real voice, real layout — drag, hover, rail, chat, panel and all. In the browser Cosmo plays a few canned lines in his actual on-device voice; on your Mac he hears you for real and answers live with any model you pick. Prefer it quiet? Mute his voice (🔊 in the rail) and just chat by typing — every feature works exactly the same, silent or out loud.
