Can AI send text messages from my own number?

Yes, but only through a device signed in to your account. There is no official iMessage API, so every tool that texts from your real number does it by driving Messages.app on a Mac. The difference between products is whose device that is — one in a farm that stays under the vendor’s control, or the one you already own.

Do I need to keep a Mac turned on?

If you want messages to come from your own number, yes. The Mac is what actually talks to Apple. Any Apple computer from the last several years works — including an older one you leave plugged in somewhere — and the connector keeps it from sleeping while it runs.

What about contacts on Android?

They get a normal SMS from your number, as long as Text Message Forwarding is on for your Mac (iPhone: Settings → Apps → Messages → Text Message Forwarding). Your iPhone has to be on and online, but it can be anywhere — it does not need to sit next to the Mac. Leave it off and Android sends fail while their replies never reach the Mac.

Is it against Apple terms to automate iMessage?

Apple’s Messages & Privacy page says iMessage is intended for family and friends and is "not for conducting commercial activities or disseminating unwanted messages," and that misuse "may result in service limitations." That is published and it covers every product in this category, since Apple has never shipped a business iMessage API. Two things worth knowing: it is not only about volume — accounts get limited at low volume, and a recently activated number sending outbound is the riskiest state there is — and recipients reporting your messages is a trigger in its own right. So do not connect a freshly bought SIM, use the line you already have real history on, and message people who want to hear from you.

How many messages can AI send per day?

There is no fixed number. The ceiling scales with your account's age and history, so an established personal Apple ID has more headroom than a freshly provisioned one. Hosted platforms publish caps near 50 new conversations a day because that is the safe figure for a brand-new account in a farm. Cold outreach draws far more scrutiny than replies in existing threads. Apple enforces these limits itself and they tighten on a number that reads as bulk outreach rather than conversation, so ramp up gradually.

What is the cheapest way to let AI text for me?

Using hardware you already own. Hosted Mac services run roughly $59 to $1,000 per line per month, and often add a setup fee of $335 to $500, because the price includes a Mac and an Apple ID. Bring-your-own-device tools charge for software only, so they land in the $29 to $59 range with no setup fee — the tradeoff being that you supply and power the Mac.

How to let AI text from your own number

There are three ways to give an AI assistant the ability to send texts, and they differ most in one dimension: whose phone number the message comes from. This page lays out all three honestly, including where each one is the wrong choice.

Can AI send text messages from your own number?

Yes, but only by driving a device that is signed in to your account. Apple publishes no iMessage API, so every product that sends from a real personal number works the same way underneath — it automates Messages.app on a Mac. The meaningful question is not whether a Mac is involved, but whose Mac it is and what you pay for that.

What are the three ways to let AI text for you?

SMS APIs give the AI a brand-new number. Hosted Mac services keep the Mac and the Apple ID on their side. Bring-your-own-device tools put the software on hardware you already own. Each trades cost against convenience against sender identity.

1. SMS API (Twilio, MessageBird, Vonage)

You provision a new number and send SMS through it. Rock-solid reliability, excellent documentation, scales to millions.

Best when you're sending transactional notifications at volume and nobody expects a personal reply. Worst when the message needs to feel like it came from a person — it arrives as a green bubble from an unknown number, and reply rates reflect that.

2. Hosted Mac service

The vendor runs a device and an Apple ID on your behalf in their farm and exposes an API in front of it. Nothing for you to install or keep running.

Best when you don't want to own infrastructure and the per-line cost is comfortable. Worst when you need many numbers — pricing typically runs $59 to $1,000 per line per month, because each line includes real hardware — or when the number matters, since it's a number the vendor provisioned, not yours.

3. Your own Mac (bring your own device)

You install a small connector on a Mac you already own. It reads and sends through your existing Apple ID, and the vendor provides the API, MCP server, and sync layer on top.

Best when you want messages to come from the number your contacts already have saved, and you have a Mac that can stay awake. Worst when you have no Mac, or can't keep one powered and signed in — if it sleeps, sends queue until it wakes.

Which approach keeps your existing phone number?

Only the third. SMS APIs and hosted Mac services both hand you a number they control. If the goal is an AI that texts as you — replying in threads your contacts already have, showing up as a blue bubble in a conversation that has history — the Mac has to be signed in to your Apple ID, which in practice means it has to be your Mac.

How do you connect an AI assistant once the Mac is set up?

Two standard paths. Most AI desktop clients now speak the Model Context Protocol, so one config entry exposes texting as native tools. Anything that doesn't support MCP can call a REST API over HTTPS from any language.

MCP — one entry connects Claude, Cursor, Codex, Cline, or n8n. Tools appear automatically in the client's tool picker.
REST API — for custom GPT Actions, CRMs, shell scripts, or anything with an HTTPS client. Webhooks push inbound replies back.

What are the real limits?

Apple rate-limits aggressive sending, publishes no official numbers, and — importantly — does not apply one ceiling to everyone. Headroom scales with the account: age, history, and how much genuine two-way conversation it carries.

That's why most hosted services publish caps near 50 new conversations a day. Their Macs run freshly provisioned Apple IDs with no history and outbound-only traffic, which is the highest-risk profile Apple sees. It's an honest limit for that architecture — it just isn't a universal one.

What holds everywhere: replies inside existing threads are treated far more leniently than cold first contact, so this architecture suits follow-up and conversation rather than cold blasting. And the limits are Apple's — no tool changes them. They tighten on a number that reads as bulk outreach rather than conversation, and that call is Apple's alone.
