From Blank to Brilliant: Custom GPTs Made Easy

October 17, 2025

In this REBLutionize Your Marketing episode, REBL shares a simple trick to get past the blank page: have ChatGPT write its own instructions. Start by stating the role, purpose, and outcomes you want, then ask it to draft the full instruction block for your Custom GPT. In a live workshop example, this turns a vague idea into a usable starter in minutes.

From there, get specific. Define the GPT’s function, audience, and focus areas, add a tone guide and word preferences, and refine based on how it answers. If replies miss the mark, update the instructions and test again. Not sure what a role like “coach” should cover? Do a quick scan with tools like Perplexity, then fold the findings into the brief. The result is a cleaner setup, faster iteration, and a GPT that consistently sounds like you.
