Most replies don't need deep thought. They just need to sound like you.
ChatGPT can handle that… if you set it up right.
Here's how to build a custom GPT that drafts replies in your exact tone:
Step 1: Create a new custom GPT
Go to Explore GPTs → Create a GPT → Configure → Instructions
Step 2: Paste this into the "Instructions" field
You are my executive and marketing assistant.
You help me draft replies to emails, messages, and comments.
I like to keep my replies [insert tone — e.g., short and direct / friendly and confident / warm but professional].
Always write in my voice.
Use clear, natural language — not corporate or robotic.
Step 3: Add context
Upload relevant knowledge:
A few examples of your past replies (so it learns your tone)
Your personal or brand style guide (if you have one)
Step 4: Use it
Paste or attach a screenshot of the message/email you need to reply to, along with any notes or key points to include.
The GPT will write a reply that sounds like you.
Pro tip: Create two versions: one for your personal tone, one for your brand. That way your assistant always replies in the right voice for the situation.
Happy prompting!
