A "one-person company" doesn't mean one person doing everyone's work—it means using AI agents to do most people's work for you. As one of the most powerful AI agent platforms available today, Codex has the full capability to call APIs, package skill modules, chain together workflows, and connect with third-party tools. In theory, it can replace video editors, designers, copywriters, operations staff, data analysts, and even programmers. But most people using Codex are still stuck at the "chatting and writing copy" stage, not knowing how to connect to large language models, how to package reusable skill modules, or how to chain Codex with tools like Jimeng, CapCut, Feishu, and Obsidian into an automated production line.

This course takes the "one-person company" concept as its core philosophy, using 20 hands-on projects to take you from zero to mastering all the core capabilities of Codex agents. Starting from the most basic installation, API integration, and interface familiarization, it gradually goes deeper into skill module packaging, then moves into real business scenarios such as automated video editing, e-commerce image/video recreation, data organization, PPT creation, Feishu office automation, storyboard short videos, digital human agents, special-effects videos, mini-program development, Obsidian knowledge bases, and WeChat official account automation. Each project starts from the underlying logic and goes through to complete hands-on implementation, ultimately packaged into reusable skill modules, so you truly have a team of AI employees on standby 24/7.

This course doesn't just cover operations—it focuses more on helping you build a practical approach to an "AI agent matrix." Each hands-on project comes with clear step-by-step breakdowns, tool invocation methods, and reusable skill module ideas that you can apply directly to your own business after learning. Whether you want to lower startup costs, boost content production efficiency, or automate your personal knowledge management, this course can help you avoid detours and truly turn Codex into an AI employee that works for you.
