Frequently Asked Questions
What makes Answrr different from other AI receptionists?
Answrr is powered by Rime's Arcana voice model—the world’s most expressive AI voice technology—making its conversations sound naturally human with emotional nuance, breathing, and dynamic pacing. Unlike generic AI systems, Answrr features long-term semantic memory that remembers every caller’s name, preferences, and past interactions, enabling personalized follow-ups like, "Hi Sarah! How did that bridge retrofit go?" It also includes AI-powered setup in under 10 minutes via a conversational onboarding assistant, triple calendar integration (Cal.com, Calendly, GoHighLevel), and MCP protocol support to connect to any business system. These features combine to deliver an enterprise-grade experience at a small business price point.
Can Answrr handle technical engineering inquiries?
Yes, Answrr can handle technical inquiries through its RAG (Retrieval-Augmented Generation) knowledge base. You can upload engineering documents, project specifications, or service descriptions, and Answrr will use them to answer client questions accurately. For example, it can explain project timelines, material options, or compliance standards directly from your documents. While it doesn’t replace an engineer’s expertise, it can qualify leads, schedule consultations, and provide preliminary information—freeing up your team to focus on complex technical work.
How does Answrr integrate with my project management tools?
Answrr supports the MCP (Model Context Protocol) tool protocol, which allows it to connect to any business system with an API. This means you can integrate Answrr with your project management tools like Procore, Asana, or Microsoft Project. For example, when a client schedules a site visit, Answrr can automatically create a task in your project system, assign it to the right engineer, and send a notification. This seamless integration ensures that every call translates into actionable work without manual data entry.
Is Answrr suitable for firms with multiple offices or locations?
Absolutely. Answrr supports multi-agent functionality, allowing you to create separate virtual receptionists for different offices, locations, or service lines. Each agent can have its own voice, greeting, calendar, knowledge base, and transfer rules. For example, one agent could handle residential projects in New York, while another manages commercial work in California. This flexibility makes Answrr ideal for growing engineering firms with distributed teams.
What happens if a caller wants to speak to a real engineer?
Answrr handles this seamlessly with smart call transfers. You can configure transfer rules based on caller intent, department, or topic. When a caller requests to speak with an engineer, Answrr will transfer the call to your team and deliver full context—such as the client’s name, project type, and previous conversation—so your engineer can pick up exactly where the AI left off. This warm handoff ensures no information is lost and the client feels valued.
How secure is my client data with Answrr?
Answrr prioritizes security with enterprise-grade protections. All sensitive data—including call recordings, transcripts, and caller memories—is encrypted using AES-256-GCM, the same standard used by banks and government agencies. Data is stored in secure PostgreSQL databases with pgvector for memory, and you have full control: you can view, export, or delete any data at any time. Answrr is GDPR-compliant and offers role-based access control, ensuring only authorized team members can access sensitive information.
