Desktop pet for Mac
A desktop pet that actually lives on your Mac.
Keep an animated screenmate beside your windows. Your desktop buddy can rest, react, remind you, celebrate, and show when an AI agent needs attention.
Interactive desktop pet
A small character with real reactions.
A Masko pet stays quiet while you work, performs reminders, reacts to music, and changes when a connected AI agent is working or waiting.

A subtle loop keeps the character alive without stealing focus.
- 02React
Agent states, music, and personal moments can trigger movement.

Water, breaks, breathing, and focus become character actions.
