Create custom instructions for ChatGPT

Overview

Custom instructions let you tell ChatGPT who you are once, so every conversation starts with that context. Instead of re-explaining your background each time, you set it and forget it.

What you'll do

1. Write a "About Me" block covering your role, industry, and career stage
2. Define your preferred response style (concise vs. detailed, formal vs. casual)
3. Add constraints like "I'm a non-technical marketer" or "I'm job searching in healthcare"
4. Test with real prompts to see the difference

Why this matters

Most people use ChatGPT like a search engine. Custom instructions turn it into a personalized assistant that understands your specific situation.
