Part of the [iMessage setup guide](https://sealgate.ai/connect/imessage) , which covers every agent and how the connection works under the hood. Paste this into your coding agent, or run it yourself in a terminal. Please help me connect iMessage to ChatGPT through SealGate on my machine. If I do not already have a SealGate account, have me sign up at https://dashboard.sealgate.ai/start/personal-messaging?utm_source=sealgate.ai&utm_campaign=seo-connect&utm_content=imessage-chatgpt first, since starting there pre-approves the Beeper connector. Then follow the setup steps at https://sealgate.ai/connect/imessage/chatgpt.md and stop whenever I need to act myself: approving this device in the browser when the installer asks, and, only if I already had an account, approving the Beeper connector in the SealGate dashboard. Requires macOS or Windows (Linux is experimental) with the Beeper desktop app installed. ## Connecting ChatGPT ChatGPT adds the SealGate gateway as a custom MCP connector, so it works from the ChatGPT web and mobile apps, not just a desktop tool. See the [ChatGPT setup guide](https://sealgate.ai/docs/connect-clients/chatgpt) for the exact steps. ## What ChatGPT can do with iMessage - Triage unread texts and draft replies in your own voice for you to send. - Summarize a long thread so you catch up in seconds. - Find that address, link, or photo someone texted you weeks ago. - Turn a text conversation into a task or calendar note. Ready to let ChatGPT handle your iMessage? Paste the setup prompt into your coding agent and you are connected in a couple of minutes. Copy setup prompt [New to SealGate?

Yes. ChatGPT can add the SealGate gateway as an MCP connector, which exposes your iMessage tools. Because a local daemon tunnels the connector out, it works from the ChatGPT apps, not just a tool running on your machine. Can I connect ChatGPT or Claude to iMessage? Yes. After you connect iMessage through SealGate, your agent can read and send texts, including from cloud and mobile apps like ChatGPT and Claude, not just local CLI tools. Do I need a Mac? iMessage runs on Apple's network, so connecting it through the Beeper desktop app needs an Apple device signed in to iMessage. Once connected, any agent you point at it can use it. Where do my messages go? Your iMessage history and login are never stored on SealGate's servers. When your agent makes a call, the request and response route through SealGate to be policy checked in memory, and only metadata about the call is logged (which tool ran, when, and which agent ran it). SealGate never stores the message content itself. What does SealGate store about my messages? SealGate routes each tool call to your connector and back, holding the request and response in memory only long enough to apply your policies, then discarding them. That check is automated: the gateway inspects the traffic programmatically to enforce your rules, and no one at SealGate can read your messages. They are never persisted and never used to train any model. SealGate keeps only call metadata (which tool ran, when, and which agent ran it), never the tool-call parameters or results, so your conversations and who you are talking to are never stored on SealGate's servers. Can the agent send texts, or only read them? Both. You decide through SealGate policies whether a given agent can only read, or can also send, and every send is recorded in the audit log as metadata (that it happened, when, and by which agent), never the text of the message itself.
