AI App Development: Streamlit, OpenAI API & RAG Projects

About this course

This fully hands-on course teaches learners to build production-quality AI-powered web applications by combining Streamlit's rapid UI framework with the full power of the OpenAI API. Using a single progressively built project — an AI-Powered Smart Travel Planner & Itinerary Generator — learners will master every major OpenAI capability: Chat Completions with streaming, Vision API for image analysis, Structured Outputs for reliable JSON, Function Calling for tool use, Embeddings for semantic search, and the Agents SDK for autonomous workflows. Every feature is built as a new page or component in the Streamlit app, so learners see their project grow from a simple chatbot to a full multi-page AI platform with maps, itinerary exports, and real-time travel intelligence. By course end, learners will have a deployed, portfolio-ready AI application and the skills to prototype any AI-powered product in hours.
