7 Best AI Assistants for Mac in 2026
The Mac has never had more AI on it. macOS 27 shipped Siri AI on September 14, ChatGPT and Claude both have desktop apps that can click through your other apps in the background, and Raycast puts a model one keystroke away.
What still lands on you: the 7pm email asking to move Thursday, the three people you need to find a time with, the follow-up you promised Claire. Desktop assistants help while the Mac is awake and you are asking. Close the lid and the work waits.
The quick answer: Carly is the best AI assistant for Mac if you want work taken off your plate. There is nothing to install. It runs in the cloud, you email it, CC it or text it, and it works in your real Gmail or Outlook, your calendar and thousands of other apps, even while your Mac is asleep. Siri AI is the best free layer for the Mac itself.

1. Carly
Carly is an AI agent you reach the way you would reach a human assistant. Email it, CC it on a thread, text it from your phone, message it in Slack, or chat with it in any browser. Nothing to download. It does the work inside your real Gmail or Outlook and your Google Calendar or Outlook calendar, so it makes no difference whether you read mail in Apple Mail, Outlook for Mac or a browser tab.
A normal week at the desk:
- Josh asks to move Thursday. CC Carly on your reply. It checks your calendar, offers Josh times you are actually free, and sends the new invite once he picks one.
- A call with Emily, Michael and Dana. Email Carly “find 45 minutes next week with these three.” It emails them options, handles the back-and-forth, and books it.
- The client email that lands at 9pm. Carly’s agents act on their own when a message arrives, so the client asking to reschedule has three new times before you open the laptop.
- After the call. Forward the notes and say “follow up with Claire on pricing, log it in HubSpot.” The email goes out from your own address and the note lands in HubSpot.
Setting it up. Connect your mail and calendar once at carlyassistant.com/integrations. Carly connects to thousands of apps, so your CRM, task app and team chat can go on the same page. After that, every email or text is just the request.
What makes it different: every other assistant on this list lives on your Mac or waits in a chat window. Carly lives in the threads you already use and keeps working when the Mac is shut in your bag. Predictable routines, like “every receipt from this sender goes into my expenses sheet,” run as free Zapier-style workflows. Work that needs judgment, like negotiating a meeting time with three people, runs as an AI agent.
Best for: founders, consultants and professionals who spend the day on a Mac and want the email and scheduling done, not just drafted.
Pricing: Free Zapier-style workflows; AI agents from $35/month. Get started with Carly, or book a quick call and the team will set it up with you.
2. Siri AI (Apple Intelligence)
macOS 27 Golden Gate replaced Siri with Siri AI, rolling out as a beta in English. It understands personal context across your messages, mail and photos, and takes actions inside apps. Press Shift-Command-Space and Visual Intelligence answers questions about a window on your screen, like adding an event you see to your calendar. Siri can also hand a question to ChatGPT.
What makes it different from Carly: it is free, private and excellent for “what did Tom say about Friday.” It works one request at a time, on the Mac in front of you. It will not run a scheduling negotiation with a client, and it is not watching your work inbox at 2am.
Best for: quick help with anything already on your Mac.
Pricing: Free on Macs with M1 or later. Apple applies daily usage limits to its cloud-backed features.
3. ChatGPT for Mac
In July, OpenAI merged ChatGPT and Codex into one new desktop app with Work, an agent that runs multi-step tasks and can use your computer in the background. Since August it can read and send Apple Messages with your approval, and on paid plans its scheduled tasks can start when a Gmail message, Slack message or GitHub pull request arrives.
What makes it different from Carly: those three are the whole trigger list, so an Outlook email or a calendar change starts nothing. Tasks that use your Mac’s own files need the Mac on and the app running, and many Mac users call the new app cluttered. See Claude vs ChatGPT for how the two compare.
Best for: drafting, analysis and hands-on tasks across the apps on your Mac.
Pricing: Free plan; Go ~$8/month; Plus ~$20/month
4. Claude for Mac
Claude’s Mac app is folding Cowork into ordinary chat: ask for something and Claude decides whether it is an answer or a task. On Pro and Max, computer use (in beta) lets it click, type and open apps in background windows on macOS 15 or later, without taking your pointer. It is the strongest of the chat apps at reading a long thread and telling you what you actually agreed to.
What makes it different from Carly: anything that uses your Mac’s own apps needs the Mac awake, and closing the lid puts it to sleep. Its cloud routines run on a schedule or on developer events, not when a client emails. See Claude vs Carly and our Claude Cowork review.
Best for: careful writing, long documents and hands-on tasks on your own files.
Pricing: Free plan; Pro $20/month billed monthly ($17/month billed yearly); Max from $100/month
5. Raycast AI
Raycast is the launcher many Mac power users already live in, and its AI Chat now uses your Raycast extensions, writes and runs code, and keeps going until a task is done. Since September 10, paid users can plug in their own Claude or ChatGPT subscription.
What makes it different from Carly: it is the fastest way to ask a model something from anywhere on the Mac, and nothing happens until you open it.
Best for: keyboard-first users who want AI in the launcher they already use.
Pricing: Free plan; Pro $10/month ($8/month billed yearly); Pro+ $20/month; Max $50/month
6. Perplexity
Perplexity’s Mac app is the best research assistant on the desktop, with cited answers. Paid plans also get Personal Computer, an agent you open by pressing both Command keys that works across your Mac’s files and apps, and Perplexity recommends running it on a Mac mini left on around the clock.
What makes it different from Carly: the agent works best on a Mac that never sleeps, and it is built around files, to-do lists and research rather than answering the people who email you. See Perplexity pricing for the tiers.
Best for: research with sources, fast.
Pricing: Free plan; Pro ~$20/month; Max $200/month
7. Microsoft Copilot
The free Copilot app for Mac opens with Option-Space and offers the same features as the web version, minus a few like Deep Research. With a Microsoft 365 plan, Copilot also works inside Outlook, Word and Excel for Mac.
What makes it different from Carly: it finds and drafts, and you do the sending, booking and chasing. See Claude vs Copilot.
Best for: Microsoft 365 users who want AI inside the Office apps on their Mac.
Pricing: Free app; Microsoft 365 Personal $9.99/month; Microsoft 365 Premium $19.99/month
Picking an AI assistant for your Mac
Turn on Siri AI first; it is free. Add ChatGPT or Claude for a thinking partner, Raycast if you live on the keyboard, Perplexity for research, Copilot if you are all-in on Microsoft, and a dictation app like Superwhisper if you would rather talk than type. More options are in our best AI assistant apps roundup.
If the problem is that your inbox and calendar still run on you, go with Carly. Email it, CC it or text it, and the meeting moves, the reply goes out and the follow-up happens, whether or not your Mac is open.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
