Build a Custom GPT/Gem for a Repeated Task

10. Automation, Agents & Advanced Projects ⏱ 25 minutes min 📊 Intermediate

Objective

Create a saved, reusable custom AI assistant configured for one specific recurring task.

1

Identify a task you repeat often (e.g., writing weekly social posts in your brand voice, answering FAQs).
2

In ChatGPT, use 'Create a GPT' (or in Gemini, 'Create a Gem') and describe its purpose, tone, and any rules it should follow.
3

Paste in reference material it should always use (your brand voice guide, FAQ, or price list).
4

Test it with a real request and refine the instructions based on the result.
5

Save/name it clearly so you can find and reuse it easily.

Instructor TipThis is the payoff tutorial for anyone who built a Brand Voice Guide earlier — encourage them to paste it in directly.

TakeawayA well-configured custom assistant means you never have to re-explain your rules and preferences again.
