AI System Prompt Generator

A system prompt is a set of instructions given to an AI assistant that defines its role, personality, capabilities, and constraints. It shapes how the AI responds to user queries and ensures consistent, on-brand interactions. System prompts are used in ChatGPT, Claude, and other AI models.

Copy the generated prompt and paste it into the system message field when setting up your AI assistant. In ChatGPT, you can use it in the Custom Instructions or when creating a custom GPT. For API integrations, include it as the system message in your API calls.

Absolutely! The generated prompt is a starting point. Feel free to edit, add, or remove sections to better fit your specific needs. You can add company-specific information, adjust the tone, or include additional constraints based on your requirements.

Yes! While named "ChatGPT system prompt," the generated prompts work with any AI model that accepts system instructions, including Claude, GPT-4, Gemini, and others. The principles of good prompt engineering apply across all major language models.

System prompts ensure your AI chatbot behaves consistently and appropriately. They help prevent off-topic responses, maintain brand voice, handle edge cases gracefully, and set clear boundaries. A well-crafted system prompt is the foundation of an effective AI assistant.
