Can Answrr handle vehicle-specific inquiries like SUV availability or insurance options?
Yes. Answrr can be trained to answer vehicle-specific questions using its RAG (Retrieval-Augmented Generation) knowledge base. You can upload documents such as vehicle catalogs, rental policies, or insurance terms. The AI then uses this information to answer inquiries accurately in natural language. For example, a caller can ask, 'Do you have any SUVs available this weekend?' and Answrr checks real-time calendar availability and responds with options. This ensures accurate, up-to-date information without requiring manual updates.
How does Answrr integrate with my existing booking system?
Answrr integrates with your existing booking system via triple calendar sync—supporting Cal.com, Calendly, and GoHighLevel. When a customer books a rental, Answrr checks real-time availability, confirms the booking, and sends a confirmation email. For agencies using custom systems, Answrr’s MCP protocol allows direct integration with any API-accessible system, including custom booking platforms or CRMs. This ensures seamless data flow and eliminates double-entry.
