Your AI agent's personality isn't just about sounding nice — it directly impacts how customers perceive your brand and how effective the agent is at its job. Here's how to choose wisely.
Match Your Brand Voice
Your agent should sound like it belongs on your website. A law firm's agent should be professional and precise. A children's toy store agent can be playful and enthusiastic. A healthcare provider needs warmth and empathy above all.
Ask yourself: if a customer read the agent's response without knowing it was AI, would it feel consistent with the rest of your brand?
The Personality Presets
KaHappy offers several personality presets as starting points:
- Friendly: Warm, conversational, uses casual language. Great for consumer brands, hospitality, and community-oriented businesses.
- Professional: Clear, structured, authoritative. Ideal for B2B, finance, legal, and enterprise.
- Concise: Gets straight to the point. Perfect for technical support, reference desks, and FAQ-heavy use cases.
- Empathetic: Prioritizes understanding and acknowledgment. Best for support scenarios where customers may be frustrated.
- Expert: Deep, detailed explanations. Suited for educational content, complex products, and advisory roles.
Custom System Prompts
For maximum control, use the custom prompt option. Here you can define specific behavioral rules:
- "Always start by acknowledging the customer's question"
- "Keep responses under 3 paragraphs unless the user asks for more detail"
- "If you don't know the answer, say so honestly and suggest contacting [email protected]"
- "Never discuss competitor products"
Test with Real Scenarios
Before publishing, test your agent with real customer questions — not just easy ones. Try edge cases, frustrated tones, and ambiguous queries. A personality that sounds great in theory might need tweaking when it meets real-world conversations.
