Build Custom AI Tools with Claude and ChatGPT APIs

Artificial intelligence is transforming software, but you do not need to be a machine learning expert to build AI-powered applications. By leveraging APIs, you can embed powerful language models directly into your own custom tools. This foundational text-based course guides you through the essentials of connecting to Claude and ChatGPT. You will start with basic terminology, understanding how APIs work, and progress to writing the code required to send prompts and process AI responses. Through written explanations and clear code snippets, you will gain the confidence to build your own intelligent text-processing scripts. What you will learn: Understand core API concepts, JSON data formatting, and authentication basics; Write fundamental code to send requests and receive responses from Claude and ChatGPT; Apply modern prompt engineering techniques to get reliable, structured outputs; Explore fundamental Retrieval-Augmented Generation (RAG) patterns for contextual AI responses; Practice handling asynchronous API calls and managing rate limits effectively. The curriculum flows logically from foundational definitions to practical implementation. You will read through step-by-step written guides and examine realistic code examples that you can adapt for your own projects. Designed entirely for beginners and developers new to AI integration, this course requires no prior machine learning experience.
