This tutorial teaches how to build an AI-based sentiment analysis chatbot for WhatsApp and SMS using OpenAI's API, Twilio Functions, and Twilio Studio. The chatbot is designed to simulate conversations and respond to user prompts and questions, with the ability to analyze the sentiment of incoming messages. To get started, users need to set up a Twilio account, create an OpenAI account, and obtain an API key. They then create a Twilio function using OpenAI's client library and deploy it to Twilio Functions. Next, they create a Twilio Studio flow that integrates with the chatbot function and routes incoming messages accordingly. The tutorial provides guidance on setting up the chatbot's functionality, including fetching sentiment analysis and generating content based on user input. Users can connect their Twilio number to their Studio flow using Messaging Service, allowing the chatbot to receive and respond to incoming messages automatically. With this setup, users can build a basic AI-based sentiment analysis chatbot for WhatsApp and SMS.
