AI in TypeScript

Build AI-powered applications with TypeScript. Type OpenAI API responses, model chat messages with interfaces, build typed prompt pipelines, and create type-safe AI utilities. Follow the ideas in small steps: first understand the concept, then practice it in the browser, and finally connect it to a realistic coding problem. Each lesson builds on the previous one so the track becomes a skill you can explain and use, not just a list of terms.
