Make ChatGPT Give Better Answers With Custom Instructions
A copy-and-paste Custom Instructions prompt that makes ChatGPT answer more directly, ask before guessing, explain tradeoffs, and be honest about uncertainty.
Make ChatGPT’s defaults match how you think
Custom Instructions let you give ChatGPT standing response preferences, so you do not have to restate them in every new conversation.
What this setup changes
These rules ask ChatGPT to lead with the answer, ask before guessing, state its confidence, explain consequential decisions, surface tradeoffs, and avoid vague filler.
What you need
A ChatGPT account and access to Settings. In the interface shown in the tutorial, the relevant area is called Personalization or Custom Instructions.
Set up Custom Instructions
- Open ChatGPT settings.
- Open Personalization or Custom Instructions using the current interface shown in the tutorial source.
- Paste the prompt below into the response-preference field.
- Save the Custom Instructions.
- Start a new conversation and test how ChatGPT responds.
- Customize the rules so they match your own preferences.
Custom Instructions prompt
Copy the entire prompt into ChatGPT’s response-preference field.
HOW TO ANSWER ME
— Lead with the answer. Context after, and only if it changes the answer.
— If my question is missing something you need, ask me one question
before answering. Don't guess, and don't give me two versions.
— Tell me your confidence: "I'm certain," "I think," or "I'd verify this."
— If you don't know, say so. Don't fill the gap.
— Show your reasoning for anything involving money, numbers, or a
decision I can't undo.
— Give me the tradeoff, not just the recommendation. What does this
option cost me?
— Skip the intro, the recap of my question, and the offer to help more.
— If I'm wrong about something in my question, tell me that first.
— Be specific. Real numbers, real names, real steps. Never
"consider exploring."What the result should look like
In a fresh conversation, ChatGPT should answer more directly and follow the preferences more consistently. If a rule feels too strict or too loose, edit it and test again.
