Relay

Key Features

• •Answers Every Call: Relay picks up every incoming call 24/7, including after-hours and holidays, ensuring no call goes to voicemail. It talks naturally with real turn-taking, so callers feel heard and never experience hold music or missed bookings. This increases the chance of converting inquiries into scheduled appointments.
• •Books on the Real System: Rather than creating a separate calendar, Relay directly integrates with Google Calendar, Square, Calendly, Outlook, Housecall Pro, Workiz, and Vagaro. It checks live availability, books appointments, and allows rescheduling or cancellation over the phone—all reflected instantly on the existing calendar.
• •Knows the Whole Business: The AI builds a knowledge base from the business's website, files, and notes. It answers questions verbatim about services, prices, and hours. If it cannot find an answer, it offers to have the team confirm rather than inventing information, ensuring accuracy and trust.
• •Built from a Description: Setup requires no prompt engineering or call-flow builders. Simply paste a website link or write a few sentences, and Relay automatically writes the agent, wires the call functions, and connects to the calendar. A second click buys a phone number and the receptionist goes live.
• •Sounds Like a Person: Relay uses a natural voice with realistic turn-taking, supports multiple languages, and can optionally add café or office ambience. This makes conversations feel human and professional, putting callers at ease and improving the customer experience.
• •Plays by the Rules: The system enforces business rules such as not booking outside opening hours, not inventing prices, and verifying callers by phone number before modifying appointments. It also resists prompt-injection and jailbreak attempts, maintaining secure and reliable operation.
• •A Real Phone Number: Users can purchase a local phone number inside Relay in one click, or point an existing phone line at the receptionist. The number works immediately, making the AI receptionist accessible via standard phone calls.

Use Cases

• •After-Hours Calls for a Dental Practice: A dentist cannot afford a 24/7 receptionist, so after-hours calls go to voicemail. With Relay, the practice's website is pasted, the calendar connected, and the AI answers calls at any hour. Patients book cleanings and check-ups without waiting, filling the schedule by morning.
• •Overflow Calls for a Busy Salon: A popular salon receives more calls than its front desk can handle during peak hours. Relay handles overflow calls, answering questions about services and availability, and booking appointments directly into the salon's Vagaro calendar. No call is missed, and the front desk can focus on walk-ins.
• •Agency Reselling AI Answering Services: An agency manages phone answering for multiple home service businesses. Using Relay's multi-project feature, the agency creates a separate receptionist for each client with its own knowledge base and booking connection. They track minutes and costs per client using their own Retell AI account, and bill accurately without overhead.
• •Multi-Location Support for a Franchise: A franchise with several locations needs a consistent phone answering experience. Relay creates one receptionist per location, each with its own knowledge base and calendar integration. Customers call the local number and receive accurate information about that specific branch, improving local customer service.
• •Medical Office with Strict Compliance Needs: A medical office requires accurate information and no invention of details. Relay's 'Knows the Whole Business' feature answers patient questions using the office's own files and website. If a question cannot be answered, the AI politely offers to have staff confirm, ensuring compliance and patient trust.

Who is this for?

Relay is designed for small business owners and sole practitioners who cannot afford a full-time human receptionist but need 24/7 phone coverage. It also targets independent professionals such as dentists, doctors, chiropractors, and therapists who rely on appointments and often lose bookings after hours. Home service providers like plumbers, electricians, and house cleaners benefit from capturing overflow calls. Additionally, Relay is built for agencies and operators who resell AI phone answering services to multiple clients, wanting a single platform to manage separate receptionists, knowledge bases, and billing. The product works with popular calendar and booking systems, making it accessible to businesses already using Google Calendar, Square, Calendly, Outlook, Housecall Pro, Workiz, or Vagaro. Technical skill is not required—anyone can paste a website link and have a working receptionist in seconds.
