Both want ⌥ Space.
That collision is the first practical thing anyone running both discovers, and it is a fair summary of the comparison: two apps with similar ambitions on the Mac, differing less in how clever they are than in what they can reach once they are open.
The shortcut clash, and how to settle it
Option-Space has become the default “summon the assistant” combination on macOS, which is convenient right up to the moment you have two assistants. Install both and one of them silently loses: the key press goes to whichever app claimed it, and the other seems not to respond at all.
Nothing is broken and nothing needs reinstalling. One app has the key and the other does not, and the fix is thirty seconds in whichever app you summon less often.
Launchers make it worse. Raycast, Alfred and several Spotlight replacements want the same combination, so a Mac with a launcher and two assistants has three contenders for one key press. Our shortcuts guide covers how to work out which app currently holds it and how to change Meta AI's, and the same logic applies in reverse if you would rather ChatGPT moved.
A useful convention if you keep both: give the shortcut to the one you use for quick, interruption-style questions, and open the other from the Dock when you are settling in for a longer session. Muscle memory only has room for one.
How they differ on a Mac
Focused on what changes your day rather than benchmark scores. Where ChatGPT's details move between releases, we say so rather than printing something that will age badly.
| Meta AI for Mac | ChatGPT for Mac | |
|---|---|---|
| Price to start | Free Limits bite on image and video generation. What meters. | Free tier Paid plans above it; pricing changes, so check OpenAI rather than us. |
| Mac requirements | Narrow Apple silicon and macOS 15 or later. No Intel build at all. | Check current Requirements have shifted across releases OpenAI's own page is the source. |
| Summon shortcut | ⌥ Space Same key, same problem. Settle the clash. | ⌥ Space Also reassignable, and worth doing if Meta AI is your quick one. |
| Reading what is on screen | One window, snapshot You attach a window and it captures it once. How it works. | Its own approach Different model, and what it supports has changed. The practical difference. |
| Typing into other apps | System-wide dictation Types into whatever has focus. The clearest gap. | Not equivalent Voice input goes into its own window rather than your document. |
| Permissions asked for | Three Screen Recording, Accessibility, Microphone. What each grants. | Similar in kind Screen and accessibility-style access for its own context features. |
| Ecosystem it plugs into | Meta's apps Instagram, Facebook, WhatsApp, and connected accounts you authorise. | Developer ecosystem Custom assistants and a large third-party tooling world around it. |
| Acting on your behalf | No It reads and answers. Muse is the separate app that acts. | Increasingly Agentic features have been arriving; capability varies by plan. |
| Windows version | None Mac first, nothing announced. Availability. | Yes A genuine advantage if you move between platforms. |
| Footprint | 16 MB native AppKit and SwiftUI, instant to open, invisible idle. Our review. | Heavier Larger install; fine on a modern Mac, not as featherweight. |
| Where your data goes | Meta's servers Plus a stated training position. Summarised here. | OpenAI's servers With its own controls and policies. Settle this at the source, not here. |
| Best single reason to pick it | Dictation into any Mac app, free. | Breadth, portability and the tooling around it. |
Meta AI details are from our own three weeks with the 1.0 beta. ChatGPT details are described at a level that survives its release cadence; for anything specific pricing, requirements, which context features are live check OpenAI's documentation, which is the only source that stays current.
Two ways of seeing what you are working on
Both apps want to answer questions about the thing in front of you, and they go about it differently enough that the choice between them is partly a choice between two philosophies.
Meta AI is explicit and coarse. You pick a window, it takes a snapshot, that snapshot goes with your question. Nothing happens unless you choose it, which is easy to reason about and the price is friction, because a snapshot goes stale the moment you scroll. In our testing that friction was enough to stop us using a feature we admired.
ChatGPT's Mac app takes a more integrated route, reading content from apps it supports rather than asking you to hand over a picture. That is smoother when it fits what you are doing and more variable in what it covers, and OpenAI has changed the details more than once, so it is worth checking what is currently supported rather than trusting any write-up.
Explicit and predictable, or integrated and smoother. Neither is the right answer in general; they are different bets about how much you want to think about it.
One thing worth saying plainly: neither is watching your screen in the background, and both need permissions that sound alarming when you read them. That is the nature of any app that can see what you are doing, and it is the part to think about before installing either. What Meta AI asks for.
Pick by what you do, not by which is cleverer
On general chat quality they are close enough that the honest answer is “both are fine”. The differences that actually decide it are about reach, platform and price.
Being free, light and hands-free
- Dictation that types into any Mac app the single feature we kept using after three weeks.
- A 16 MB native app that opens instantly and costs nothing to leave installed.
- No paywall to think about unless you generate images or video in volume.
- Connections into Instagram, Facebook and WhatsApp if that is where your life already is.
- A very predictable screen-context model: you choose the window, nothing else is seen.
Breadth, portability and tooling
- Running on Windows too, which matters the moment you use more than one kind of machine.
- Custom assistants and a large ecosystem of third-party tools built around it.
- A longer track record on the Mac, with more releases behind the current build.
- Broader Mac support historically, where Meta AI excludes Intel outright.
- More movement on acting rather than only answering, depending on your plan.
Running both, without them fighting
They are free to install, they do not conflict beyond the keyboard, and after a week you will know which one you reach for. Five minutes of setup makes that week pleasant.
Decide which gets ⌥ Space
Give it to whichever you use for quick interruptions. The other opens from the Dock, and you will stop noticing within days.
Reassign the loser immediately
Not later. A shortcut that silently does nothing is the single most common reason people conclude an app is broken. How to change Meta AI's.
Give each one a job
Ours settled as dictation and quick screen questions in Meta AI, longer research and anything needing tooling in ChatGPT. Yours will differ.
Grant permissions per app, deliberately
Both will ask for screen and accessibility-style access. Granting to one says nothing about the other, and you can decline either. What that means.
Watch the menu bar
Two assistants both launching at login is more presence than most people want. Turn off the one you open deliberately. Where that setting lives.
Revisit after a month
One of them will have quietly won. That is the real comparison, and it is more useful than any table including ours.
If you would rather not install either, both work in a browser and neither browser version asks for any permissions at all. What you give up that way.
Comparison questions
Can I run Meta AI and ChatGPT on the same Mac?
Yes, and plenty of people do. The one thing to sort out first is the keyboard shortcut, because both reach for Option-Space by default and only one can win. Change it in whichever you summon less often. How we set it up.
Which is better for working with what is on screen?
They work differently rather than one being better. Meta AI snapshots one window you explicitly attach predictable, but stale after any change. ChatGPT takes a more integrated route whose coverage has shifted across releases, so check OpenAI's current documentation. The two philosophies.
Which one is free?
Both have a free tier. Meta AI's Mac app is free with limits that bite mainly on image and video generation. ChatGPT has a free tier plus paid plans, and pricing changes often enough that OpenAI's own page is the only sensible source.
Does either type into other Mac apps?
Meta AI's system-wide dictation types into whichever app has keyboard focus, which needs Accessibility permission. That is the clearest practical difference we found between the two on macOS, and it is the reason we kept Meta AI installed. How it works.
Do they have the same Mac requirements?
Not necessarily. Meta AI needs Apple silicon and macOS 15 or later with no Intel build at all. ChatGPT's Mac requirements have changed across its releases, so check OpenAI before assuming an older Mac is excluded.
Which should I pick if I can only have one?
If you want dictation into any app and already live in Meta's apps, Meta AI. If you want breadth, Windows support and the tooling ecosystem, ChatGPT. For plain chat quality both are good enough that workflow matters more than model. The split.
Is one more private than the other?
Both send what you type to their own servers, so neither keeps things on your Mac. They differ in stated training practices and the controls offered, and both publish policies which is where that question should be settled rather than on a comparison page. What Meta says.
Why does one of them stop responding to the shortcut?
Because the other took it. macOS gives a global shortcut to one app, silently, and the loser simply does nothing. Add a launcher like Raycast or Alfred and there are three contenders for one key press. Finding out which holds it.
Which is better at coding?
We did not test either seriously on code, so we are not going to pretend to a verdict. ChatGPT has the longer track record and the larger developer ecosystem around it, which is a reasonable prior; Meta has its own coding-oriented model in Muse Code, which is a different product from the Mac assistant.
Will this comparison stay accurate?
The shape of it should. The specifics will not both products ship frequently, and ChatGPT in particular changes what its Mac app can do between releases. We have deliberately avoided printing numbers that age badly, and we update the page rather than leaving it stale.
Install both. Give one the shortcut.
They are free, they coexist fine, and a week of using them will settle it better than any table.
