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 Mac that is — one in a data center you rent, 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 Mac released in the last several years works, including a Mac mini left on a shelf, and the connector keeps it from sleeping while it runs.

Is it against Apple terms to automate iMessage?

Automating your own Messages.app on your own Mac under your own Apple ID is ordinary local automation, the same category as AppleScript. What draws trouble is volume: sending like a bulk marketing platform from a personal Apple ID risks rate limiting or account flags regardless of the tool you use.

How many messages can AI send per day?

Apple does not publish limits, but the observed soft ceiling is roughly 50 new conversations per Apple ID per day, and sustained bursts above about 200 messages per hour tend to draw throttling. Replies inside existing threads are far more forgiving than cold first-contact messages.

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 because the price includes a Mac and an Apple ID. Bring-your-own-device tools charge for software only, so they land near $29 per month, with the tradeoff 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 rent you a Mac in a data center. 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 Mac and an Apple ID on your behalf in their data center 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 and publishes no official numbers. The community-observed ceiling is around 50 new conversations per Apple ID per day, with throttling appearing above roughly 200 messages per hour. Replies inside existing threads are treated far more leniently than cold first contact — which means this architecture suits follow-up and conversation, not cold blasting. No tool changes those limits, because they're enforced on Apple's side.
