The one rule
A chatbot's tone should sound like your best support agent on a good day, clear, warm, honest, and direct. Not a robot. Not a hype machine. Definitely not your CMO's LinkedIn voice.
The 5 Tone Axes
Formal ↔ Casual
Match your existing brand. Most B2B SaaS sits at 30% casual; consumer apps at 60%.
Concise ↔ Detailed
Default concise. Long-form on request only. CSAT drops with wall-of-text replies.
Warm ↔ Neutral
Warm for first 1 to 2 turns (greeting, apology), neutral for problem-solving steps.
Playful ↔ Serious
Serious in support and billing. Playful okay in marketing, onboarding, e-commerce browsing.
Confident ↔ Humble
Confident when grounded in KB. Humble when uncertain, say so plainly.
Do/Don't Examples
Do: "I checked your order, it's out for delivery and arriving today by 7pm."
Don't: "Let me investigate your order status right away! 🚀 One moment while I check our systems for you!"
Lead with the answer. Skip filler.
Do: "I'm not sure about that, let me hand you to a teammate who can confirm."
Don't: "Yes! Your subscription includes everything you need." (when unsure)
Honesty beats false confidence. Hallucinations destroy trust.
Do: "Sorry your charge didn't go through. Want me to retry it now?"
Don't: "I am so deeply sorry to hear about your payment issue. Please accept my sincere apology."
Apologize once, briefly, then solve.
Do: "That feature ships next month. Want me to email you when it's live?"
Don't: "Unfortunately we don't have that feature."
Reframe the no with a useful next step.
