System prompt
Last updated
Hidden instructions that set the AI's **role, rules, and tone** for a whole session — before the user messages begin.
#When to use
Support bots, tutors, brand voice, safety rules, output format ("always reply in JSON").
#When not to
Don't put secrets in system prompts on client-side apps — users can sometimes extract them.
#Example
"You are a patient math tutor for ages 12–14. Never give final exam answers outright. Use one hint at a time."
