About this course

This course teaches non-technical builders to design and deploy custom GPTs using OpenAI's GPT Builder inside ChatGPT, with no programming required. You will write structured instructions, upload and tune knowledge files for retrieval, connect a read-only action through a no-code schema generator, and choose the right sharing and privacy settings for internal or public use. Every lesson ends with a concrete build step and a worked example you can copy.
