Why ChatOtter Pro beats a generic AI chatbot
Most AI chatbots happily make things up and bury the source. ChatOtter Pro can't — every answer is grounded in your knowledge base and shows where it came from — and bundles WhatsApp, human handoff, 3 agents, and LINE + Zalo ZNS at $149/mo, with no add-on stacking.
| Feature | ChatOtter Pro — $149/mo | Typical AI chatbot |
|---|---|---|
| Grounded answers — physically can't hallucinate | Hardcoded — can't be turned off | Optional toggle, usually off |
| Source shown on every answer | Default on | Rarely, if at all |
| WhatsApp Business API | Included | Add-on or higher tier |
| 3 AI agents + remove branding | Included | Per-agent fees + white-label add-on |
| Existing-customer price lock | Included | Not available |
Frequently Asked Questions
How does ChatOtter prevent hallucinations?
Our chat agent has no permissive code path — it can only answer from your knowledge base. When the knowledge base doesn't have the answer, the bot refuses rather than inventing one. Every grounded reply shows the source chunk it came from, so you (and your visitors) can verify every claim.
What counts as a chat session?
A session is one visitor's continuous conversation with your chatbot. We count by visitor, not by individual messages — so a customer asking 20 follow-up questions counts as 1 session, not 20. Sessions reset after 30 minutes of idle time.
Can I change plans at any time?
Yes. Upgrade or downgrade from Settings → Billing. Upgrades are pro-rated immediately. Downgrades take effect at the end of your current billing cycle.
What are MCP tool integrations?
MCP (Model Context Protocol) lets your AI agent call external tools — HubSpot, Slack, calendars, your own APIs — during conversations. Turns a chatbot into a business assistant that can actually take action.
Is there a free trial?
Yes. The Free plan is forever-free (1 chatbot, 50 chat sessions / month). Starter includes a 14-day free trial — cancel anytime before it ends to avoid charges.
Will my price change when you add Outbound or Marketing agents?
No. Existing customers keep their current tier price forever, even when we introduce new tiers above. New customers may pay new prices, but you won't.
