Riley Brown walks through 28 practical Codex examples in a long-form course. He distinguishes the model from the Codex desktop workflow and demonstrates building web, iOS and desktop experiences, using a browser, and working with documents, sheets and slides.
The examples expand into projects, parallel tasks, plugins, skills, automations, images, video analysis and computer use. Brown shows how connected tools and external services can extend an agent's work, while emphasizing prompts and the review of generated results.
The tour is a map of possible workflows rather than a controlled comparison of models or a guarantee that every feature is available to every account. Configuration, permissions and product support may vary. Brown's self-promotional links and subscription requests are omitted from this record.
