Frequently Asked Questions
What happens when the AI support bot doesn't know the answer?
It gracefully summarizes the conversation history, tags the appropriate team queue, and hands off the ticket to a human agent without frustrating the customer.
Can AI agents safely process refunds and cancellations?
Yes, by connecting to Stripe, Shopify, or internal billing APIs with predefined business constraints (e.g. auto-refunds up to $100 for verified accounts).
