AI customer service on WhatsApp: answers, bookings and triage around the clock

An AI agent for WhatsApp and your website that answers questions, books appointments and hands off to your team. For clinics, real estate and schools.

01The problem

Messages go unanswered after hours, the front desk repeats the same answers all day, and bookings get lost.

02How we solve it

An agent connected to the official WhatsApp Business API and your website that answers from your company's information, checks and writes to your calendar or system, and hands the conversation to a staff member with the full history. Sensitive topics follow fixed rules.

03How it works

01Message02Agent replies03Fixed rules04Booking or handoff
  1. Message

    The customer writes to your official WhatsApp number or your website chat.

  2. Agent replies

    Answers use your approved company information: services, prices, addresses and hours.

  3. Fixed rules

    Sensitive topics, limits and off-script requests follow rules you define with us.

  4. Booking or handoff

    The agent books the appointment or passes the conversation to your team, with the full history.

The highlighted step is the check: anything that fails the rules goes back for review instead of moving on.

04What changes in practice

  • Answers after hours. Customers get a reply at night and on weekends, with no queue.

  • No more lost bookings. The agent checks and writes appointments straight to your calendar or system.

  • A team free for what matters. Repetitive questions leave the front desk, and delicate cases reach a person with the full history.

05What you get

  • Agent configured with your company information
  • Calendar or system integration
  • Conversation dashboard with human handoff
  • Monthly service report
