WUKO is a small 3D robot who lives on your Mac, and he’s a pet more than an app. You feed him RAM chips, give him sponge baths and play with him, and he grows: 36 moods, 14 bond tiers from Stranger to Soulmate, a drawing every night, a diary, songs of his own. He chats, remembers what you tell him, and brings you the weather and news if you want. His brain ships inside the app (that’s why it’s 4.5 GB), so your chats are never sent to third-party AI servers.
