Choose your use case and get a ready-to-use system prompt.

The System Prompt Generator writes a starting system prompt for a chosen use case. Pick a role such as general assistant, coding assistant, customer support, content writer, data analyst, or tutor, add optional custom instructions, and copy the resulting prompt into your API call. It is for developers who need a solid baseline to iterate from rather than a blank text box. Generated prompts cover role, tone, and guardrails, and you can edit any part.
A system prompt defines the model's role, tone, scope, and rules: what it should do, how it should format answers, what it must avoid, and when to ask for clarification or refuse. Keep it specific and free of contradictions.
Yes, but they need simpler instructions. Short imperative rules work better than long nuanced guidance on small models, while larger models can follow layered constraints, personas, and formatting specifications.
Run a fixed set of realistic inputs, including edge cases and attempted misuse, and score outputs against your requirements. Change one instruction at a time and keep the previous version so regressions are easy to spot.
