Snacks that do things
Six foods to start with, each with its own effect. Pizza fills him right up but makes him sleepy; milk perks him up.
A desktop pet for your Mac
A little friend is moving onto your desktop.
A plush pet that lives just above your Dock: a raccoon, a cat, a fluffy blob, or one made from photos of your own dog. Feed it, play with it, tuck it in at night, and it keeps you company while you work, chatting back when you talk to it.
Food · Fun · Energy
Feed him. Play with him. Tuck him in.
He has three needs, shown in the paw up in your menu bar. Keep them up and he's a happy raccoon; let them slip and he'll come and tell you about it.
Play, fetch and a dance
Pick him up and throw him across the screen, play fetch or hide & seek. He'll forgive you. He'll even ask for more.
Naps and bedtime
He gets sleepy at night and naps when his energy runs low, with a little "good night" you get to read first. Click to wake him.
What's in the Feed menu
Per serving, out of a full bar of 100

And a wardrobe: tick what he wears, pick its colours and patterns (stripes, dots, checks, knit), or let him dress for the weather himself.

Chat & voice
He talks back.
Type to him or just talk out loud. He answers in his bubble and in his own voice, remembers your day, and slowly grows a personality of his own.
- ✨Apple's on-device model works out of the box on Macs with Apple Intelligence: nothing leaves your Mac.
- 🔑Or your own OpenAI key for richer chat and a real speaking voice.
- 📔A diary of your days together. He'll bring things up later.
long day… what did we do this morning?
You fixed that bug before coffee and I ate three blueberries 🫐 We make a good team!haha. ok, nap time for you
Okay… wake me up if you need me 😴Listening…
Plugin store
He starts with the fun stuff. You choose what he learns.
Out of the box he's just your pet. Reminders, a to-do list, meeting heads-ups, the weather: each one is a plugin you add when you want it, and his menu grows to match. Try it: add one here and he'll learn it.
Characters & packs
Pick your pet. Or bring your own.
Start with Szopi the raccoon or any of his twelve plush friends, or make your own in the character editor. Drop in a few photos of your real pet (or a favourite toy) and it designs the plush for you (this uses your OpenAI key). Packs add more: new snacks, new friends and photo-booth backdrops, installed with a double-click.
Make your own pack
A pack is a zip with a manifest.json, a character exported from the editor and a picture or two. No code runs, ever: every pack is checked before it's installed.
