From Dialogue to Execution: Building an AI Healthcare Agent with GPT-4o-mini and Playwright

We’ve all been there: you feel a nagging pain or a sudden fever, and the last thing you want to do is navigate a clunky hospital portal, find an open slot, and manually type out your symptoms for the tenth time. What if your AI could do it for you? In this tutorial, we are building an Autonomous Healthcare Agent using GPT-4o-mini and Playwright . By leveraging autonomous AI agents and healthcare automation , we will create a system that checks your availability via the Cal.com API , summarizes your symptoms, and executes a browser-based booking on a hospital portal using GPT-4o-mini Function Calling . The Vision: AI That Acts, Not Just Talks Most LLM implementations stop at "giving advice." We’re taking it a step further into the realm of Action-Oriented AI . Our agent won't just say "you should see a doctor"; it will actually find a time that works for you and fill out the forms. The Architecture The flow involves a multi-step orchestration where the LLM acts as the brain, determining
