Build an AI-powered SMS support system with Twilio, GPT-4 and PostgreSQL

How it works

1. User Signup & Verification: The workflow starts when a user signs up. It generates a verification code and sends it via SMS using Twilio.

2. Code Validation: The user replies with the code. The workflow checks the code and, if valid, creates a session for the user.

3. Conversational AI: Incoming SMS messages are analyzed by Chat GPT AI for sentiment, intent, and urgency. The workflow stores the conversation context and generates smart, AI-powered replies.

4. Escalation Handling: If the AI detects urgency or frustration, the workflow escalates the session—alerting your team and sending a supportive SMS to the user.
