1. Introduction and Problem Statement:

  • Real estate agents lose 71% of leads not contacted within 5 minutes of form submission.
  • The video demonstrates how to build a no-code voice AI agent to address this issue.
  • The agent answers questions, qualifies leads, and schedules tours.

2. Solution Overview:

  • Utilizes Naden as a backend to initiate calls upon form submission.
  • Employs Retail AI to control voice agent interactions, ensuring zero hallucination.
  • The solution includes scheduling tours, checking availability, and booking appointments.
  • A free downloadable template of the workflow is provided.

3. Demo Walkthrough:

  • A form is submitted with sample data (name: Sam, random email/phone, property: 524 Retail Lane).
  • Upon submission, a phone call is initiated to the provided number.
  • The voice AI agent (Chloe from Retail Real Estate Company) engages in a conversation.
  • The agent confirms interest in the property, offers to schedule a tour, and checks availability.
  • The agent uses cal.com integration to find available slots (e.g., 9:00 AM to 10:00 AM, 11:00 AM to 3:00 PM on Friday, August 1st).
  • The agent books the tour for 12:00 PM on Friday, August 1st, after confirming the email address ([email protected]).
  • The agent confirms the booking details and offers further assistance.

4. Post-Call Processing:

  • A webhook is triggered after the call to summarize the conversation.
  • The summary and other data (name, email, phone, property) are updated in a Google Sheet.

5. Building the Voice AI Agent:

  • The workflow template can be downloaded from a free community (Light).
  • The template is imported into Naden via the "import from URL" option.
  • The video emphasizes the growing importance of voice AI agent skills.

6. Form Submission Node:

  • The form can be customized with additional fields (e.g., budget).
  • Various form integrations are supported (form.io, Formstack.trigger, etc.).
  • Webhooks can be used to grab information from forms on external websites.

7. Retail AI Node and Multi-Prompt Agent:

  • Retail AI is a no-code voice AI platform (retailai.com) offering free credits.
  • A multi-prompt agent is created within Retail AI.
  • The multi-prompt agent ensures zero hallucination by controlling each state of the conversation.
  • A universal prompt defines the agent's identity, style, and conversation guidelines (e.g., be concise, address one topic at most).
  • The "edit prompt tree" allows defining different states (introduction, scheduling, call back).

8. State-Specific Prompts and Transitions:

  • Warm Intro: Greets the customer by name (dynamic variable from the form), confirms availability, and offers a tour.
  • Schedule Tour: Asks the user for availability, calls the "check availability" function (connected to cal.com), and books the appointment.
  • Call Back: Asks the user when is a good time to schedule a call back if they are not available initially.
  • Transitions between states are defined based on user responses (e.g., "yes" to a tour transitions to the "Schedule Tour" state).

9. Tools and Functions:

  • Check Availability: Connects to cal.com to retrieve available time slots.
  • Booking Appointment: Books the appointment via cal.com.
  • Call Transfer: Transfers the call to a human representative if the customer asks questions outside the agent's scope.
  • Cold transfer automatically transfers the call. Warm transfer allows the agent to provide context to the human representative.

10. Webhook Integration:

  • A webhook from Naden is added to Retail AI's webhook settings.
  • This webhook sends the call transcript and other information to Naden.
  • Naden uses this data to summarize the conversation and update the Google Sheet CRM.

11. Additional Resources and Opportunities:

  • Retail AI voice AI course with Naden is available for certification.
  • The course covers Retail AI functionalities and step-by-step builds for various use cases (appointment reminders, lead qualification, etc.).
  • AI agency course is offered to teach how to start an AI agency.

12. Notable Quotes:

  • "Real estate agents lose 71% of leads that are aren't contacted within 5 minutes of their form submission on showing interest."
  • "...zero hallucination because we will actually control every state of this voice agent."

13. Technical Terms:

  • Hallucination: When an AI generates incorrect or nonsensical information.
  • Multi-prompt agent: An AI agent that uses different prompts for different states of a conversation to avoid hallucination.
  • Webhook: An automated HTTP request made by an application when something happens.
  • Dynamic variable: A variable whose value can change during the execution of a program.

14. Conclusion:

The video provides a detailed guide on building a no-code voice AI agent for real estate lead qualification and appointment scheduling. By leveraging Naden and Retail AI's multi-prompt agent, users can create a solution that minimizes lead loss and ensures accurate, controlled conversations. The availability of a free template and certification courses further empowers users to implement and monetize this technology.
