This workflow enables dynamic AI-driven database querying and interaction through a user-initiated chat interface. It integrates a chat trigger that users activate, sending their questions to an AI agent connected to a PostgreSQL database. The AI agent processes the user’s input, performs relevant database queries, and generates responses using OpenAI’s GPT-4 model. This setup facilitates intelligent data retrieval and interaction, useful in scenarios like customer support, FAQ automation, or data exploration for website admins.
