CodexGuide

CodexGuide (codexguide.io) is a free, Chinese-language learning platform dedicated to OpenAI Codex, with 71 continuously maintained articles. It is built for Chinese-speaking developers and knowledge workers who want to use Codex for real work instead of only reading about it.

Beginners start with what Codex is and who it is for, then learn how to choose between the Codex App, CLI, IDE extension, and Cloud. Step-by-step guides walk through logging in, opening a first local project, and making and reviewing a first change.

Advanced guides explain how Codex works under the hood, how to manage context so the agent stays on track, and how permissions, sandboxing, and approvals set safety boundaries for an AI coding agent working on your files.

Case studies cover practical workflows: browser end-to-end acceptance testing, using the Notion plugin, collaborating across sessions, running long tasks, building reusable skills, and remotely controlling a Mac. Each case shows the request, the change Codex made, and how the result was verified.

A troubleshooting FAQ covers the problems people actually hit, including login failures, permission errors, Git issues, and verification that does not pass.

Every guide follows the same task-oriented loop: understand the request, make the change, verify the result, and iterate. The goal is simple: help Chinese-speaking users go from opening Codex for the first time to finishing a real, checkable task. All content is free to read, with no sign-up required.

The site is organized into four clear tracks (getting started, advanced topics, case studies, and FAQ), so readers can jump straight to what they need. Articles are updated as Codex itself changes, and each one links to related guides so a reader can move from a single question to a complete working setup without hunting across forums or scattered blog posts.
