Best AI assistants for iMessage in 2026
For business calls, bookings and reminders from an iPhone text thread, Arlo is an assistant you can text directly. Pally and Poke also offer messaging channels. ChatGPT’s Mac Messages plugin and Apple Intelligence are different routes for existing conversations or help composing a request.
For errands from your iPhone, look for an assistant you can text directly. Arlo can take that message into a business call, booking request or reminder, without a separate chat app.
We make Arlo. Official product descriptions linked below were checked 3 November 2026. This compares published features and plans, not hands-on benchmark results.
Choose the interaction first
| Option | Fits this request | Check before choosing |
|---|---|---|
| Arlo | Text a personal task, booking or business call | Task details, required connections and current allowance |
| Pally | Text tasks through iMessage or RCS | Separate permissions for existing message history |
| Poke | Delegate through its Messages channel | Account channel support and whether human help is needed |
| ChatGPT Messages plugin | Search, draft or send in existing Mac threads | Apple silicon Mac, Work or Codex, and permissions |
| Apple Intelligence ChatGPT extension | Ask Siri or get help composing text | Supported device, language and region |
A contact you can text
Arlo takes personal requests through iMessage and SMS, including calls, bookings and tasks. It can navigate phone menus and wait on hold. It checks unclear requests, spending and actions that cannot be undone. See pricing for the current free allowance and call rates.
Pally's published channels include iMessage and RCS. Its free offering has usage limits that refill through the week. The optional paid Cloud Mac is separate from texting the assistant; general texting does not require that add-on. Compare that distinction in Arlo vs Pally.
Poke lists Messages alongside WhatsApp and Telegram. Verify signup support for your number. Its FAQ describes Poke Human as a person handling calls and errands under Ultra. Arlo vs Poke covers the broader choice.
ChatGPT on a Mac is a different route
OpenAI's Apple Messages plugin can read, search, draft and send in existing Mac conversations. It is available on all plans in Work and Codex in the Apple silicon macOS app. It requires permissions and asks for send approval by default, though a user can allow future sends to a chat. It does not let you text ChatGPT remotely from your iPhone.
Apple's ChatGPT extension helps through Siri and Apple Intelligence on eligible devices and in supported regions. It also is not a Messages contact.
Try Arlo with one task
An illustrative request: "Remind me on 6 November at 9am Europe/Rome to send the signed form. Confirm the reminder channel and time." Check the full date and delivery channel in the confirmation.
Texting Arlo does not open your other conversations; separately authorized connectors have their own access. For any provider, distinguish a direct conversation from permission to search history. The message-to-task guide explains how to review a forwarded request.
Start free with Arlo, connect Messages and send one task you want off your list. You can delegate the phone menu, queue and conversation from the same thread.
Frequently asked questions
Which iMessage assistant is best? Shortlist by the job: a contact for delegation, a Mac plugin for existing threads, or Apple's tools for composing. Compare the same request and required access.
Can I text ChatGPT from my iPhone in iMessage? The documented Mac plugin does not provide that interaction. It works with Messages on an Apple silicon Mac in Work or Codex.
Are iMessage AI assistants free? Some offer free use with limits. Check current allowances, paid add-ons and any calling charges before treating a free plan as unlimited.
Can an assistant read my other messages? A direct thread and history access are separate. Arlo receives messages you send it; connectors require separate authorization. Review other providers' permissions individually.
