Ever Wish You Could Clone Yourself? Now You Can.

You Don't Have to Do It All Yourself Anymore.

Marketers ask me the same question again and again: “How do I use AI without losing my voice — or worse, my firm’s voice?”

It’s a fair fear. When you’re responsible for brand messaging, thought leadership, and relationship‑building, the last thing you want is content that sounds generic or inconsistent.

The good news: ChatGPT lets you to create a clone — a custom-trained model that writes in the voice you choose. And for most marketers in professional services, the clone you need first isn’t your personal voice.

It’s your firm’s.

This streamlined guide walks you through how to build your firm‑level clone and why it matters.

What Is a ChatGPT Clone?

A ChatGPT clone is a customized version of the model trained on specific writing samples, tone guidelines, strategic messaging, and brand rules. Think of it as a writing partner that already understands your voice before you begin.

You can — and should — create more than one clone, but for the purpose of this guide we’ll focus on the firm-level clone — the version that ensures consistency, accuracy, and brand alignment across all content.

Why Start With a Firm‑Level Clone?

Professional‑services marketers juggle countless communication touchpoints — BD materials, email campaigns, website updates, client alerts, social posts, pitches, proposals, internal announcements, and leadership comms.

A firm-level clone ensures:

1. Consistency Across Channels Your firm’s tone and messaging remain steady, no matter who is drafting.

2. Faster Drafting, Fewer Rewrites You spend less time correcting tone, terminology, or structure.

3. Protection of Brand Voice A clone enforces voice standards automatically.

4. Easier Collaboration Teams, assistants, and agencies can draft materials in the correct voice from the start.

Before You Begin: Check Firm Policies

Some organizations restrict public ChatGPT. Many law, consulting, finance, and healthcare firms are rolling out enterprise versions instead.

Before building a clone, ask IT or Knowledge Management:

• Do we allow ChatGPT?

• Do we have an enterprise version?

• Am I permitted to create a brand‑voice clone?

• Where should writing samples or style guides be stored securely?

• Is the firm already developing a centralized clone? 

  
  

Here's How to Create Your Firm‑Level Clone in ChatGPT (Once You're Given the Green Light)

Step 1: Gather 5–10 Writing Samples

Collect materials that best represent your firm’s voice:

• Website copy

• Pitch decks and BD materials

• Client alerts or articles

• Style guide or brand voice guide

• Messaging pillars

• Boilerplates
  

These are the foundation of your firm-level clone.

Step 2: Open the Custom GPT Builder

Go to Explore → Create a GPT and name it clearly:

• “Firm Brand Voice Clone — [Firm Name]”

  
  

Step 3: Upload Your Samples (and Firm Style Guide)

Drag and drop your writing samples and Style Guide directly into the builder.

Step 4: Add the Core Instruction

Paste the following into the GPT’s behavior/instructions section:

“Use the uploaded Firm Style Guide and writing samples as the authoritative reference for voice, tone, terminology, formatting, and structure. Apply these rules to every draft. If user instructions conflict with the guide, ask for clarification before proceeding.”

Step 5: Add Guardrails

Include boundaries such as:

• “Follow firm‑approved terminology only.”

• “Maintain a professional, concise tone.”

• “Avoid jargon unless included in the Style Guide.”

• “Keep structure clear and scannable.”

  
  

Step 6: Test and Refine

Ask the clone to complete real tasks:

• “Draft a LinkedIn post in the firm’s voice.”

• “Summarize this client alert using our tone.”

• “Rewrite this paragraph using the Firm Style Guide.”

  
  

Adjust if needed.

**Using a Clone Inside a Project

Using your firm-level clone inside a Project in ChatGPT ensures every draft reflects your firm’s voice and maintains the strategic context of the project itself.**

Projects store context, not voice — but they pair perfectly with your clone.

For long‑term work (brand building, campaigns, proposals, multi‑step writing), load your clone within a Project so ChatGPT remembers:

• goals

• constraints

• audience

• prior drafts

• decisions already made

  
  

This creates a powerful combination: Clone = how it writes. Project = what it remembers.

Want a Personal Clone Too?

Once your firm-level clone is built, you can create a second clone using the same steps, simply swapping in:

• your writing samples

• your tone preferences

• your personal guardrails
  

Most marketers eventually find that using both clones side-by-side gives them the flexibility they need across all communication channels.

It’s the perfect setup for marketers balancing:

• official firm content, and

• personal thought leadership.

  
  

Final Thought

The future of marketing isn’t about choosing between AI and authenticity. It’s about using AI to protect and scale the voices that matter.

A firm‑level clone helps you maintain brand consistency while saving time. A personal clone helps you expand your own point of view.

Both work even better when used intentionally.
