Waking up in 2026 to find your routine emails answered, your reports drafted and your biggest decisions flagged for review is no longer a thing of science fiction films. We’ve officially entered the Digital Twin era with ChatGPT. You can think of a digital twin as an AI version of you trained on your tone, decisions and workflow. In other words, we’ve moved beyond AI being just a chatbot for quick answers, but a virtual double that acts on your behalf as a “System of Action.”

Unlike standard assistants, these twins are continuously learning models that mirror your specific logic, communication style and priorities.

While this may sound a little creepy, it’s actually a beneficial way to work smarter, not harder. So if you’re ready to scale your expertise without hitting burnout, here is how to build your own personal AI clone.

ChatGPT Plus, you’re going to want to create a Custom GPT. Select “Create a GPT” to start the build. I use a simple framework I call FRED to structure its instructions:

Functionality: Define exactly what the twin will do (e.g., “Draft my LinkedIn posts” or “Summarize my meetings” or “Respond to my emails”).Response Style: Be specific. Tell it to be “warm and conversational” or “direct and professional.”Expertise: Set its identity (e.g., “You are a senior project manager with 10 years of experience”).Document Sources: Upload your gathered Hero Content directly into the GPT’s knowledge base.

Gartner IT predict digital twin technologies will become increasingly embedded in enterprise systems, helping automate data-heavy and repetitive tasks while humans focus on strategic and creative work.

By offloading routine mental load to an AI that understands your preferences and workflow, you can spend less time on busywork and more time on decisions that matter.
