What Is a Custom Instructions Generator?
Custom instructions are a settings feature in ChatGPT and similar assistants, two boxes, what the AI should know about you, and how it should respond, that apply automatically to every new conversation. This tool builds both blocks from a short form so you don’t have to write them from scratch.
The tool above is free, runs entirely in your browser, and doesn’t send your input anywhere.
How to Use This Free Custom Instructions Generator
- Describe your role or background in the first field.
- Pick a tone and response length, or leave them on “No preference.”
- Add any other response preferences, one per line.
- Click “Generate Custom Instructions,” then paste each block into your assistant’s custom instructions settings.
Why Custom Instructions Save You Repeating Yourself
Without them, you end up re-explaining your role or preferred style at the start of every new chat. Custom instructions apply automatically, so a new conversation already knows you’re a marketing manager who wants short, direct answers, without you typing that again.
Frequently Asked Questions
Is this custom instructions generator free to use?
Yes. It’s completely free, has no sign-up, and runs in your browser.
Where do I paste these in ChatGPT?
Under Settings, Custom Instructions (or Personalization, depending on your version), there are two fields matching the two blocks generated here.
Does this work with assistants other than ChatGPT?
Most assistants with a similar feature use the same two-part structure, or you can combine both blocks into a single system prompt if needed.
Can I update these later?
Yes, just regenerate with different answers any time your preferences change.
