Set the boundaries once

It knows when to come get you
Four moments trigger a hand-off. Each one sends an alert straight to your email or WhatsApp, with the conversation attached.
- Customer asks for a human using phrases like “agent” or “real person”
- AI finds a possible answer, but confidence is too low to reply.
- The question falls outside the knowledge base or Q&A.
- Customer asks the same question again because the issue remains unresolved
