Frequently Asked Questions

What makes Answrr different from traditional answering services?

Answrr is fundamentally different because it uses Rime Arcana, the world’s most expressive AI voice technology, to deliver conversations that sound completely natural and human-like. Unlike traditional services that rely on scripted human operators or robotic AI, Answrr’s AI remembers every caller across interactions, enabling personalized greetings and context-aware responses. It also features real-time appointment booking with Cal.com, Calendly, and GoHighLevel, plus AI-powered setup in under 10 minutes. Traditional services lack long-term memory, automated scheduling, and the ability to scale without hiring more staff.

Can Answrr handle technical engineering inquiries?

Yes, Answrr can handle technical engineering inquiries through its RAG (Retrieval-Augmented Generation) knowledge base. You can upload project specifications, engineering standards, or service documents, and Answrr will use them to answer questions accurately. For example, it can explain material requirements, clarify design timelines, or provide information about structural codes. The AI understands context and can refer to your documents to provide precise, up-to-date answers during after-hours calls.

How does Answrr ensure data security for sensitive project information?

Answrr uses enterprise-grade security with AES-256-GCM encryption for all data, including call recordings, transcripts, and caller memories. Your data is stored securely in PostgreSQL with pgvector, and you have full control—every piece of information can be viewed, edited, or deleted at any time. The platform is GDPR-compliant and does not sell or share customer data. This ensures that sensitive project details, client information, and engineering specifications remain protected at all times.

Is Answrr suitable for small engineering firms with low call volume?

Absolutely. Answrr is designed for small and medium businesses with flexible pricing. The Starter plan starts at $99/month with 300 minutes included, which is ideal for firms with low to moderate call volume. You only pay for what you use, and overages are priced at $0.25/minute. The AI onboarding assistant makes setup effortless, and you can start using it in under 10 minutes—perfect for solo engineers or small teams who need a professional phone presence without complexity.

Can Answrr integrate with my existing project management software?

Yes, Answrr supports the MCP (Model Context Protocol), which allows it to connect to any business system via API. This means it can integrate with your project management tools, CRM, accounting software, or custom systems. For example, it can create a new project in your system when a client schedules a consultation, update task statuses, or send automated reminders. This level of integration ensures that every call results in a documented action, keeping your workflow efficient and error-free.

What happens if a caller wants to speak to a human engineer?

Answrr handles this seamlessly with smart call transfers. You can configure transfer rules based on caller request, topic, or department. When a caller asks to speak to an engineer, Answrr routes the call to your team with full context—transcript, call summary, and key details—so no information is lost. This ensures a smooth handoff and eliminates the need for callers to repeat themselves, providing a professional experience that builds trust.

How does Answrr’s long-term memory work?

Answrr’s long-term memory system uses semantic search to remember every caller. After each call, the AI analyzes the conversation, extracts key facts (name, contact info, project interest, preferences), and stores them securely. When the same caller returns, Answrr retrieves relevant memories and greets them personally—'Hi Sarah! How did that foundation project turn out?' This creates a personalized experience that builds loyalty and makes clients feel valued, even after months or years.
