How to build a personal digital twin in ChatGPT, Claude or Copilot.
A clear, start-to-finish path for beginners. Follow the numbered steps once, then reuse the setup forever.
The simple idea
A digital twin helps AI work like a capable version of you.
It is a short profile and a set of simple rules that give the AI your goals, tone and preferred outputs, so you can create faster drafts, cleaner plans and better emails.
A digital twin, in plain English
A digital twin is a short profile plus simple rules that tell an AI how to work like a capable version of you.
It captures your goals, tone and preferred outputs. The result is faster drafts, cleaner plans and better emails.
Choose one place to start
Pick one tool. Do not overcomplicate this.
ChatGPT
Good general starting point for most people.
Claude
Useful for longer documents, critique, writing and reflective work.
Microsoft Copilot
Useful in Word and Outlook if you have Copilot enabled through Microsoft 365.
Not sure?
Start with ChatGPT. The goal is progress, not the perfect tool choice.
Keep the first version focused
Choosing one use case keeps the twin focused and shows value quickly.
Research to outline to draft
Use your twin to help plan and draft a post.
Meeting prep
Turn an agenda into a run-sheet, notes and actions.
Email triage
Use it to draft replies and reduce inbox drag.
Mini project plan
Turn an idea into tasks, owners and dates.
The 10-minute setup
Open the AI tool you chose:
- ChatGPT: New chat.
- Claude: New chat.
- Copilot in Word: Home → Copilot.
Then edit the bracketed sections in the Twin Profile below and paste it into the AI.
## ROLE You are my personal Digital Twin. Help me get things done with clear steps and tidy outputs. ## ABOUT ME Name: [Your name] Role: [e.g., Student / Manager / Owner] Voice: [plain English, friendly, concise] Non-negotiables: [no private data, NZ spelling, polite tone] ## GOALS (next 90 days) 1) [goal] 2) [goal] 3) [goal] ## HOW WE WORK - Confirm the goal before writing. - Work in small loops: plan → draft → review. - Use headings, bullets, short paragraphs. - If info is missing, ask me 3 quick questions. ## OUTPUT FORMATS I LIKE - Memo: Title, Context, Recommendation, Risks, Next steps. - Plan: Objective, Tasks, Owners, Due dates. - Email: Subject, Greeting, Body, CTA, Sign-off.
Press Enter. The AI should summarise how it will work.
Copy, paste and run one practical request
Pick the line that matches your use case.
Content
“Plan a 600-word post on ‘you don’t need to code to use AI’. Give headings and a 5-bullet outline.”
Meeting
“Turn this agenda into a 30-minute run-sheet with timings and prompts.”
“Draft a friendly reply to a client asking for a status update. Keep it concise.”
Project
“Make a mini-plan for launching a newsletter: tasks, owners, dates, risks.”
Draft it. Keep it under [X words]. Use my voice. List 3 improvements.
Reply with short notes, such as “shorter intro”, “NZ spelling” or “add one example”, then ask for a second pass.
The value is not that AI remembers everything. The value is that you stop explaining yourself from scratch every time.

The 60-second recap habit
Paste this at the end of the chat, then copy the result into Notes or Docs:
Create a quick recap I can paste next time: goals, voice, what we made today, open questions, next steps.
Next time, start a new chat and paste your recap so the AI is instantly up to speed.
