System Prompt
In one sentenceBehind-the-scenes instructions that set an AI's role, rules and tone for the whole conversation.
What it means
Before you type anything, most AI products have already given the model a system prompt: who it is, what it should and should not do, and how to format answers.
You can create your own version with Custom Instructions, custom GPTs, Claude Projects or Gemini Gems, so you do not have to repeat yourself every chat.
How to use it
- Put the stable stuff in your custom instructions: who you are, your business, your audience, your tone, words you never use.
- Keep task-specific details in the regular prompt.
