A writing partner in your voice
One assistant with two jobs: it coaches the thinking, then it drafts the way you sound.
Learn the pattern once. The same steps work in a ChatGPT Custom GPT, a Claude Project, a Gemini Gem, and a Microsoft 365 Copilot agent.
- 1
Start with a real conversation
Name your role, who you write for, and the topic. Answer its questions. That interview becomes the persona.
- 2
Show it writing you stand behind
A few samples across the formats you actually use. Let it infer the tone, then correct the style note it writes back.
- 3
Keep two modes
Coach mode asks and sharpens. Writer mode drafts in the voice you agreed on. Coaching stays the default.
- 4
Save it, then improve it on real work
Turn the instructions into a custom assistant. Keep the building chat so you can update the voice when the work changes.
Free in the Mastermind. The full guide includes the prompts, the two-mode instructions, and how to save them.
