Health · 24/7 Conversational Agent

From 15-Minute Calls to 2-Minute Bookings

Intelligent multi-channel agent (WhatsApp + Web) that understands natural language, suggests specialists based on symptoms, schedules appointments considering real availability and processes payments. Works 24/7 without rest.

Visión General

The chatbot automates the complete clinic booking experience, integrating Twilio for WhatsApp, AWS serverless and AI agents with LangGraph. Patients interact naturally via WhatsApp, receive intelligent specialist suggestions based on symptoms, check real-time available schedules and confirm appointments with integrated secure payment. The system uses DynamoDB and JWT to ensure continuity and security in each session, with the ability to resume interrupted conversations.

El Desafío

The clinic appointment booking process was slow and frustrating: long phone wait times, availability limited to business hours, frequent booking errors, low patient satisfaction and high administrative burden on reception staff.

Nuestra Solución

Omnichannel conversational chatbot integration with AI, using LangGraph and LangChain to orchestrate complex flows. The agent handles context throughout the conversation, validates identity with OTP and JWT, suggests specialists based on naturally described symptoms, shows synchronized real availability, processes payments integrated with Mercado Pago and confirms appointments automatically. Serverless workflows guarantee infinite scalability and minimal costs.

Resultados

78% of requests handled completely by the chatbot without human intervention. Average booking time reduced to <3 minutes (previously 15+ minutes). Customer satisfaction increased to 4.7/5 stars. 23% reduction in cancellations thanks to automatic reminders. Annual savings of $5,600 USD by avoiding hiring additional staff. 24/7 availability increased overnight bookings by 200%.
