About this app
Your agent works. Now you can see it. Yuki is a girl at a desk by the window — headphones on, a cat asleep on the sill. When your coding agent gets to work, she types. The moment it needs an answer, she looks up and knocks on the glass. When it winds down, so does she. She makes your agent feel alive — not a spinner in a terminal, but someone quietly working beside you. WHAT SHE DOES - Mirrors your agent live: working, waiting, idle. - Knocks when you're needed, so you can stop staring at the terminal. - Full-screen on iPhone and iPad, a small desktop window on your Mac. - Every device reacts at once. HOW SHE CONNECTS Install the free Mac Helper on the Mac you code on, and she lights up. The Helper is open source — you can read every line before you trust it — and it shares only your agent's status. It works with Claude Code and Codex today, with more on the way. Until it's set up, Yuki plays a built-in preview so you can meet her first. PRIVATE BY DESIGN Your code never leaves your machine. Only your agent's status travels — working, waiting, idle — over your own network or your own iCloud, never through us. No server. No account. No tracking. App Store privacy label: Data Not Collected. HER WORLD Lo-fi music and the soft clack of her keyboard set the mood. Treat her to her daily coffee. Stay a while — she keeps a few secrets for those who do. Never code alone.
