常见问题

Which of these 10 features should I learn first?

Start with the three that give you the fastest ROI: Batch file renaming (saves 10-30 minutes every time you organize a messy folder), Data and chart analysis (turns hours of spreadsheet work into a 30-second prompt), and PPT creation (eliminates the most universally dreaded office task). These three alone can save 3-5 hours per week for most office workers. Once those feel natural, add scheduled automation to handle recurring tasks while you sleep.

How is ChatGPT Codex different from the standalone Codex app?

ChatGPT Codex is the integration of Codex capabilities directly into the ChatGPT desktop app — you can toggle between "Work" mode (standard ChatGPT) and "Codex" mode (agent capabilities) in the top-left corner. The standalone Codex app is a separate download focused purely on agent tasks. For beginners, the integrated version is easier: one app, one subscription, and you can switch modes depending on whether you need a chatbot or an agent. The standalone app is preferred by developers who want Codex as their primary workspace.

Are my files safe when Codex accesses them locally?

Yes. Codex's local file access means files stay on your computer — they are not uploaded to OpenAI's cloud. This is different from ChatGPT's web interface where you upload files to the server. Codex reads and processes files locally, similar to how a desktop app like Excel or Photoshop works. For sensitive business documents, this is a significant privacy advantage. The persistent memory feature also stores preferences locally, not in the cloud.

Can I combine multiple features in one task?

Yes, and that's where Codex really shines. A typical workflow might be: (1) analyze the Q3 sales spreadsheet (feature 2), (2) create a presentation from the analysis (feature 7), (3) convert the presentation to a web page for sharing (feature 3), and (4) schedule this entire workflow to run every Monday morning (feature 5). You can chain these in a single conversation or set up an automation that runs them sequentially. The plugin ecosystem (feature 6) lets you extend this further — for example, auto-emailing the final web page to your team via Gmail.
