These aren't settings. They're keywords you type before your prompt, and ChatGPT changes how it answers. That's also why you can make up your own.
Truth Mode
Asks it to tell you what's actually wrong instead of going along with you. Use it when you're about to commit to a plan.
TRUTH MODE: here's my plan for raising prices next month. What's wrong with it?
Red Team
Plays devil's advocate and finds where your plan breaks. Use it before a big decision or launch.
RED TEAM: I'm about to hire a second office manager. Find every way this goes wrong.
ELI10
Explains anything like you're ten years old. Use it on anything full of jargon: tax, contracts, finance.
ELI10: what is gross margin, and how do I work mine out?
/human
Cuts the AI slop, so it stops sounding like a robot. Use it on any email or post that goes out under your name.
/human: rewrite this email to a customer whose job is running a week late.
Checklist
Describe a job the way you'd explain it to a new hire, and it turns it into a step-by-step checklist you can hand to anyone.
CHECKLIST: every morning I open up at 7, check the van, call back yesterday's leads, and get quotes out before lunch.
Make your own
Define a word once and it holds for the rest of the chat:
When I type SHORT, answer in three sentences or fewer.
These are prompt words, not hidden features. They work because you told it what you want.
