What it does

CodexGuide is a Chinese-language (but globally aimed) knowledge base for navigating OpenAI’s sprawling Codex ecosystem. It walks beginners through their first desktop-app task, helps developers wire up the CLI and AGENTS.md, and gives team leads templates for sandbox rules, approvals, and reusable playbooks. The whole thing is published as a VuePress site at codexguide.ai, with the GitHub repo serving as a staging ground for contributions.

The interesting bit

The project treats Codex not as a coding assistant but as a multi-interface “AI workflow system”—and then does the tedious work of mapping which interface suits which job. The “entry map” comparing CLI, Cloud, IDE, desktop app, and ChatGPT mobile is the kind of boring-but-valuable matrix that official docs rarely provide.

Key highlights

• Curated paths for three audiences: first-timers, developers integrating real projects, and teams building shared norms
• Covers non-dev use cases explicitly: PPT generation, Obsidian workflows, browser automation, clinical literature reviews
• Security boundaries front and center: sandboxing, command approval, credential handling
• Each key page carries a “last verified” date against official OpenAI sources
• Built with VuePress, MIT-licensed, actively seeking case studies and error solutions

Caveats

• Content is primarily in Chinese; English README exists but coverage is unclear
• Sponsored by API resellers (PPToken, Ciyuan API), which may color the third-party API connection guides
• Community-maintained, not official; explicitly warns that pricing and availability drift fast

Verdict

Grab this if you’re in China or read Chinese, use multiple Codex interfaces, and want opinionated workflows rather than reference docs. Skip if you need deep English content or live entirely inside one tool (say, Cursor) with its own documentation.
