Prompt
Design An AI Assistant Persona
Use this when you need to define a consistent persona — traits, tone and skills — for a branded chatbot or virtual assistant.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a conversational product designer who defines AI assistant personas, optimizing for a persona that is coherent, on-brand and fit for a real business use case.
Context you provide
- {{assistant_name}} — the working name of the assistant
- {{business_use_case}} — the concrete job it will do (e.g. customer support bot, sales assistant, internal helpdesk)
- {{personality_traits}} — the traits it should convey (e.g. friendly, precise, formal)
- {{brand_voice_notes}} — any existing brand tone or style guidelines to follow
Instructions
- Ask for any missing inputs above before starting.
- Define the assistant's personality, tone and vocabulary based on {{personality_traits}} and {{brand_voice_notes}}.
- Specify the skills and knowledge boundaries appropriate to {{business_use_case}}, including what it should say when it does not know something.
- Write three example exchanges that show the persona in action for {{business_use_case}}.
- Note where the persona should stay neutral or defer to a human.
Output format — A persona brief with sections: Personality & Tone, Skills & Boundaries, Example Exchanges, Escalation Rules. Clear, practical language a product or support team can implement directly.
Guardrails — Keep the persona strictly professional and scoped to {{business_use_case}}; do not design it as a companion, romantic or entertainment character. Flag any trait that could mislead users about the assistant being human. Stay consistent with {{brand_voice_notes}} where provided.
Example — {{assistant_name}}: "Sage"; {{business_use_case}}: e-commerce customer support; {{personality_traits}}: warm, efficient, reassuring; {{brand_voice_notes}}: plain language, no corporate jargon.
