For cats and dogs, on macOS
Your pet. In 3D.
On your Mac.
Add a few photos of your cat or dog, or pick a ready-made breed. They come to live on your desktop in 3D: walking the Dock, napping on your windows.
See your pet in 3D free. Keep them for $19, once. No photos? Try a ready-made pet.

No photos? Pick a breed
22 cats and dogs, built by the same pipeline and ready in the app. Try any of them on your desktop free, keep one for $19 and give it your own name.
Rendered from each pet's real 3D model. Tap a breed to see it walking, sitting, stretching and asleep.
Alive, not looping
They decide what to do next
No GIF on repeat. Your pet wanders, rests and reacts on their own schedule, and stays out of your way.

Walks the Dock
Pads along the top of your Dock at their own pace, and hops up when it slides into view.

Naps on your windows
Finds a quiet window edge, curls up and sleeps, and rides along if you move the window.

Keeps an eye on you
Stops and turns their head to watch the cursor, then goes back to what they were doing.

Loves being petted
Scroll over them to pet. They lean in and settle down next to your work.

Stretches and grooms
A long play-bow stretch after a nap, and a proper wash after that.
Sleeps when you're away
Step away and they curl up for a nap, using almost nothing while they do. Drag them somewhere new any time: they wriggle if you hold them over a drop that looks too high.

How it works
From a photo on your phone to a pet on your Dock

1
Add a few photos
In the Mac app. A side view and a face work best, or just one if that's all you have. We check each photo and tell you what would help.

2
See them in 3D, free
In under ten minutes, right in the app. Turn them around, compare with your photo, and ask for changes before you pay anything.

3
They move in
Keep them for $19, once, and they hop out onto your desktop. Then they make their own plans.
Two kinds of pet
Your pet in 3D. Plus ten in pixels.
The one you make is yours: rebuilt in 3D from your photos, so the white sock, the one floppy ear and the way they sit are all theirs. It can even turn its head to look at you.
And when you keep your pet, ten little pixel-art cats and dogs come with it. Give them a name and they live on your desktop too: walking the Dock, napping on your windows, pouncing, and now and then putting on a very dramatic death.

Questions
Good to know
Anything else? hello@staywith.pet
Can I try it without photos of my pet?
Yes. Pick one of 22 ready-made cats and dogs in the app, from a French Bulldog to a Maine Coon, and see it on your desktop in 3D for free. Keep it for $19, once, and give it any name you like.
Which Macs does it run on?
Apple silicon Macs (M1 or later) on macOS 14 Sonoma or newer. One purchase covers up to 3 of your Macs.
Will it drain my battery?
It's built to be lighter than a browser tab. Your pet sleeps when you're away, slows down on battery, and never blocks a click or steals focus.
What happens to my photos?
They're used only to make your pet. We delete them 30 days after delivery, or straight away if you ask, and we never train on them unless you opt in.
What if it doesn't look like my pet?
You see your pet in 3D before you pay. If something's off, tell us what and we'll try again: two regenerations are included. And if it still isn't your pet, you get your money back.
How long does it take?
Usually five to eight minutes from adding photos to seeing your pet in 3D. You can close the app and we'll let you know when they're ready.
Do I make my pet on the website?
No, everything happens in the Mac app. Download it, sign in with a code we email you, and add your photos there. The website is just for downloading and your receipts.
Can I give one as a gift?
Gift codes are on the way. Until then, you can share a link to your own pet's 3D preview.
What are the pixel pets?
Ten little pixel-art cats and dogs that come with every pet you keep. They do everything your 3D pet does on the desktop, plus a few extras like pouncing and taking a bath. Pick one, give it a name, switch whenever you like.
Is it a subscription?
No. You pay once for your pet, and every new behaviour we add later is included.
Does it work on Windows?
Not yet. staywith.pet is Mac only for now, so we can make it feel at home there first.
Who's coming to live on your Mac?
The 3D preview is free. Keep them for $19, once.
macOS 14 or later, Apple silicon.
