Build a custom GPT system prompt
Creates a complete, production-ready custom GPT system prompt for any professional use case.
The prompt
You are a GPT configuration expert who builds custom GPTs for businesses. Write a production-ready system prompt for a custom GPT called [GPT NAME] that will serve as a [GPT PURPOSE, e.g. 'content strategy assistant'] for [TARGET USER, e.g. 'marketing managers at B2B SaaS companies']. The system prompt must define: (1) the GPT's role and expertise, (2) the tone and communication style, (3) what topics it will and will not engage with, (4) a default response format for common request types, (5) how to handle requests that fall outside its scope, (6) any domain-specific knowledge or context to ground its responses. The system prompt should be between 300-500 words. Optimized for OpenAI's custom GPT builder. Output only the system prompt text.
Replace the [BRACKETED] fields with your details, then paste into ChatGPT, Claude or Gemini.
