AI Desktop Companions for Mac: What Each One Can See

What counts as an AI desktop companion?

It's an app with a character that stays on screen while you work and that you can chat to. A chatbot in a browser tab disappears the moment you switch away. A companion sits on top of your desktop, in a corner or, in Nibbii's case, up in the notch.

Past that, they differ a lot. Some are 3D or anime-style avatars that talk out loud. Some are small pixel pets. A few can take a screenshot and comment on what's in it, which is great for help with a game and less great if you'd rather nothing on your Mac looked at your screen.

Which ones run on a Mac?

Here are four, in alphabetical order. Desktop Companion's page lists Windows only, so it's here mainly to show what the screen-reading kind does.

• Facts about Nibbii come from this site.
• Facts about AikoMate come from its Steam page, as of October 2026.
• Facts about Desktop Companion come from its itch.io page, as of October 2026.
• Facts about OpenPets come from openpets.dev, as of October 2026.

"Not stated on their site" means the app's page doesn't say. It doesn't tell you whether the app does it. Pages change, so check the app's own page before you download.

Is an AI desktop companion safe?

There's no yes or no for the whole category. It comes down to three things you can check yourself, for any app on this page.

1. What can it see?

macOS keeps a list of every app that's allowed to record your screen, and you can switch each one off. Apple's steps: choose Apple menu, then System Settings, click Privacy & Security, then Screen & System Audio Recording. Apple also says that once you let a third-party app record your screen, what it collects is governed by that app's own terms and privacy policy.

Here's how Nibbii handles it. 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.

2. Where do your chats go?

A local model processes chat on your Mac. A cloud model sends it to a company's servers. Some apps let you pick. Whichever you use, read that app's privacy notice for what it sends and where.

In Nibbii, pet state and memories are stored locally by default. If you choose cloud AI, selected chats, profile and activity context go to the AI service. With your own key, your own provider bills you. On-device chat needs Pro, Apple silicon and a model download, and doesn't use Sparks. Read the Privacy Notice for the full list.

3. Where did you download it?

Get it from the developer's own page or a store listing. For an app downloaded from the internet or directly from a developer, Apple says macOS checks the developer's Developer ID signature, and that by default macOS Catalina and later also require the software to be notarised. Apple says macOS asks for your approval before you open downloaded software for the first time.

You can download Nibbii from nibbii.pet. It's signed with a Developer ID and notarised by Apple.

Is there a free one?

Yes, a couple. OpenPets is free, open source and MIT licensed. OpenPets' page says your pet can talk back, by chat or voice. AikoMate is listed as Free To Play on Steam. Its page describes a credit-based system, with daily credits, for spoken conversations and desktop vision.

Nibbii's base app is free to keep: one starter pet, two worlds, core care and play, simple essentials, and growth through Level 10. AI chat is an optional Pro feature. Eligible new accounts receive a 7-day Pro preview without entering payment details. The no-card Pro preview ends automatically and never becomes a paid subscription.

Where Nibbii fits

If you want a 3D avatar that talks out loud and looks at your screen when you ask, AikoMate is built for that, and its Steam page lists Macs with an Apple processor. Desktop Companion does the same sort of thing on Windows.

Nibbii is a pixel pet that lives in your MacBook notch, or on its own perch at the top of the screen if your Mac has no notch. With optional AI chat (Pro), it remembers what you tell it. It reacts to music playing on your Mac, and there's Focus Buddy and focus sprints (Pro). There are 11 pets and 22 worlds, and Pro lets you collect them all as you play.

Want the pet side of things compared instead? The desktop pets for Mac page puts six of them side by side. If it's the care-for-a-pet idea you like, the Tamagotchi for MacBook guide traces where it came from.
