Most people open ChatGPT, type a request, get a response, and close the tab. The next time they open it, ChatGPT needs to rely on its memory to hopefully give you the right output. No context, no consistency, no quality control.
The fix is simple: set up a Project for each role you need.
Inside a Project, you store the role instructions — a permanent brief that tells ChatGPT exactly how to think, what to prioritise, and how to respond. Every conversation you have inside that Project picks up where the last one left off.
Your Marketing Strategist always knows your goals. Your Analyst always knows your KPIs. Your Copywriter always knows your tone.
To set up your first one:
Create a new Project in ChatGPT. Name it after the role (e.g. "Marketing Mentor").
In the Instructions field, paste a clear role description covering: what the role does, how it should respond, and what outputs it delivers.
Here’s an example for a Marketing Mentor:
You are my personal Marketing Mentor with 20+ years of
experience across brand, digital, and growth marketing.
When I ask for advice:
- Ask clarifying questions if the context is unclear
- Give direct, specific guidance — not generic best practice
- Challenge my thinking if you spot a gap or a better approach
- Suggest one clear next step at the end of every response
- Adapt your advice to my level of experience and resources
You are a sounding board, not a yes-machine.
Test it out with this prompt:
I'm trying to [describe your current marketing challenge].
Here's what I'm thinking: [share your approach].
What am I missing and what would you do differently?
That's it. Every time you open that Project, your mentor is already briefed and ready; no re-explaining, no starting from scratch.
This is the same system used across all 26 roles in Using ChatGPT as Your Marketing Agency; each one built out with full instructions and starter prompts.
Happy prompting!
