An AI companion that lives by your notch. It chats with you, remembers what you tell it, and grows up the longer you're together. A little friend that's actually paying attention.

↓ that's your pal down there. It walks along with you as you scroll. Pick a different one in the corner.
It's a little AI companion that lives on your desktop and gets to know you.
Real chat under the notch. It knows what you're working on and what you told it last week. Runs on your own key or fully on-device, so it stays yours.
Illustrative sample. Replies are generated live by the AI model you pick, so yours will read differently.
Little reactions that add up to something that feels alive. Tap to see each one.
Little moments you catch out of the corner of your eye, a hundred times a day.
It bops along the second any music plays.
It dozes off when you wander from the keys.
Confetti when you hit a streak or level up.
A pat, and a slow, happy blink back.
It welcomes you back after you have been away.
Snacks, naps, and tiny daily wins.
Eight little characters, each with its own pixel charm. Hover one to say hi. Raise a few.
Around 20 pixel-art animations each. Idle, walk, dance, nap, snack, wave, and more.
Crowns, wings, glowing auras, capes, comets. More than seventy cosmetics to mix and match until your Nibbii looks like nobody else's.
Stack a glowing aura with a pair of wings and a crown. The same crown looks different on a fox than on a bunny. Half the fun is finding the combo that feels like yours.
New cosmetics ship in updates, right where Nibbii already lives.
Pick a pal, give it a personality, and keep it happy the easy way. It grows up the more you show up.
Choose your species and give it a name. Cat, dog, fox, bunny, axolotl, and more.
Write how it talks in one line and it talks that way. Sweet, deadpan, sassy, all yours.
Feed it, clean it, rest it, play a quick game. Four little needs, gentle streaks, no nagging.
It matures from a tiny hatchling to a full adult as you show up. Bigger, bolder, more itself.
Every day together changes its world. Your pal graduates from a sunny beach to cherry blossoms to a glowing volcano. Twenty-two living worlds, each with its own sky, creatures, and real local weather.
It learns your name if you tell it. It holds onto what you care about. It grows up while you go about your days, hatchling to adult, right there in the corner of your screen. Try it free for a week and see.

macOS 15 Sequoia or later, and a MacBook with a notch. Nibbii lives right up by that notch, so the notch is the home it needs.
It really chats. Real AI under the hood. Bring your own Venice API key for free, or run a model fully on-device on Apple Silicon with zero cloud. The little thought bubbles it shows while idling are hand-written, but the conversations are live.
Yeah. Tell it your name, your projects, what you like, and it holds onto those (up to 200 facts) and brings them up naturally in chat. Memory lives on your Mac. It does not sync between devices, and it never leaves unless you are using a cloud model.
In on-device mode it is 100% local, nothing leaves your Mac. In bring-your-own-key mode the request goes straight to your provider, we never see it. Memory is plain files on your own disk.
Optionally, and only if you turn it on with a cloud key. It can glance and cheer you on what you are working on, or you can hand it a screenshot in chat and ask about it. Off by default.
No. It dances to music and reacts to its own world, but it does not track your code editor or your coding tools. We are not going to claim a feature that is not there.
Try it free for 7 days, then twenty-nine dollars once. You own the app, no subscription for that. The AI is free when you bring your own key or run it on-device. If you would rather not manage a key, there is an optional Managed AI plan billed monthly or yearly. That part is your call.
No. It sits quietly in the background and sips resources while it keeps you company all day.
