Happy birthday, Ash! 🎉
Good luck with your launch today.
I saved you a seat. Come back soon.
That was a big week. I noticed.
Get some rest. I'll be right here.
I know how hard you've been working. I'm proud of you.
It stretches awake and waves you good morning.
The song comes on and it starts to dance.
It settles in quietly beside you and lets you focus.
Tell it to rest and it curls up for a nap.
Keep a care streak going and it celebrates the milestones.
In the morning it'll ask how that interview went.
Wings, crowns, glowing auras, capes. Stack them however you like.

Shy, bold, goofy. You pick.
Hatchling today. Older every week you're together.
Every day shapes who it becomes.
On a MacBook, your notch is its favourite home. On a Mac without a notch, Nibbii draws its own little perch up top instead. Either way, it's the same little companion.
Day turns to night. Little creatures wander past. The free app comes with two worlds, Meadow and Night, and Pro lets you collect all 22 as you play. A few only turn up in their own season, so you won't catch them all at once. With Pro, your local weather rolls in too.

Nibbii makes your Mac feel a little more alive.
Turn on AI chat and the longer it's with you, the more it remembers.
The interview you were nervous for. The project you kept putting off.
It grows up in the corner of your screen, a little at a time,
until one day it just feels like yours.

Nibbii is a Mac app and requires macOS 15+.
The base app is free to keep: one starter pet, two worlds, core care and play, simple essentials, and growth through Level 10. Pro adds more pets, worlds and features.
Yes. AI chat is an optional Pro feature, with Managed AI, bring-your-own-key, and supported on-device choices available in the app.
Pet state and memories are stored locally by default. Pro can optionally sync distilled long-term memories through your private iCloud database; this is off by default, and recent raw chats stay on your Mac.
Nibbii uses high-privacy defaults. Read the Privacy Notice for the data the app can handle and your choices.
When App-aware is enabled, Nibbii uses frontmost app metadata. It does not use screen recording, screenshots, or accessibility content. Turning App-aware off stops collection and clears App-aware data.
While App-aware is enabled, Now Playing automatically collects the current track title, artist, and album from the active player. Artwork stays local; when AI is enabled, bounded title, artist, and album text may be sent to the selected AI service for comments. Turning App-aware off stops collection and clears Now Playing data.
