You can upload project documentation, service guides, or FAQs, and Answrr will answer client questions based on your own information. For example, it can explain project timelines, scope changes, or service offerings with accuracy. It also integrates with calendars to schedule consultations, send follow-ups, and route urgent calls to the right team member. With natural language date handling and smart transfers, it ensures clients get the right support at the right time—without repeating themselves.
How long does it take to set up Answrr?
Answrr’s AI onboarding assistant can set up your entire phone system in under 10 minutes. The AI interviews you about your business, services, hours, and preferences, then automatically configures your agent, voice, calendar, and transfer rules.
