Build Your AI Digital Twin on Mac — Privately, From Your Own Data

An AI digital twin is a rich, reusable profile of you — how you write, who you talk to, how your week runs, and what you care about. Most "clone yourself" services build one by uploading your data to their cloud. LMCP provides local tools to gather supported app data for your AI assistant. Your AI assistant reads across the apps you already use — Mail, Messages, Calendar, Contacts and Notes — and synthesizes a "Digital Twin" document that stays on your machine. Try a prompt like: "Build my digital twin from my Mac."

LMCP executes local tools on your device. Cloud AI providers and connected services can receive requested data; their terms apply.

What goes into your digital twin?

The twin is grounded in your actual data, not a generic bio. Your AI samples across sources to find patterns:

• Your voice — read from your sent email and your own messages: greetings, sign-offs, length, formality, emoji, the languages you switch between. This is the single most valuable signal, and it only exists in what you've actually written.
• Your relationships — from Contacts and who you talk to most: your inner circle, work vs. personal, how you address different people.
• Your rhythm — from Calendar and Reminders: recurring meetings, working hours, focus blocks, how you manage commitments.
• Your themes — the projects, decisions and topics that recur across mail, notes and reminders.
• Your tone & values — how you make asks, say no, give praise, escalate.

What can you do with your digital twin?

Once the twin exists, it makes every other AI task sound like you. Ask your assistant to "draft this reply in my voice," "answer this the way I would," "write my morning brief the way I'd write it," or "brief my new assistant on who I am and how I work." Because the twin was built from your real data, the output matches how you actually communicate — not a bland AI default.

Which AI assistants can build a digital twin?

The digital-twin skill works across every major MCP-capable assistant:

• Desktop clients — desktop AI apps connect via local stdio, and LMCP sets up the ones it can automatically.
• Web AIs — ChatGPT, Claude.ai (web), Grok and Perplexity connect through the LMCP Cloud Relay connector, which bridges the cloud assistant to your local Mac. The local tools read supported data on your Mac; requested app results can pass through Cloud Relay to the selected cloud AI for synthesis. You can save the assembled profile locally, but provider processing and retention policies still apply.
