Steps
Download the Codex app from OpenAI's official site and install it for your operating system. Sign in with your OpenAI account and wait for the workspace to load.
Open the main chat panel and type a short request, such as a one-paragraph product description. Read the reply to see how Codex responds before starting a real project.
Go to the connectors settings and link the tools or documents you want Codex to read, like a Google Drive folder or a notes file. Approve the access prompts.
Ask Codex to create a landing page for your product. Give it the headline, the key benefits and the call to action you want, then let it generate the page.
Ask Codex to set up a simple automation, such as sending a weekly summary of new signups to your email. Describe the trigger and the action in plain words.
Paste the landing page back into the chat and ask for design and copy improvements, like a shorter headline or a clearer button label. Apply the changes you like.
Request a full marketing plan with channels, a weekly content schedule and target audience notes. Ask Codex to turn it into a table you can copy out.
Use the HyperFrames tool inside Codex to turn your landing page copy into a short promo video. Review the frames and export the final file.
Tips and common mistakes
Give Codex your real product details and audience in the first message so it does not invent generic copy.
Check every generated page and plan before you publish or send it, since AI output can contain small errors.
Keep each request short and specific, then refine in follow-up messages instead of writing one huge prompt.
Questions
Do I need to know how to code to use Codex?
No. You can describe what you want in plain English and Codex builds it. Basic familiarity with web pages helps when you review the result.
Is Codex free?
Codex access depends on your OpenAI plan. Check your account settings to see whether your subscription includes it.
Can Codex connect to my own files?
Yes. The connectors settings let you link documents and tools so Codex can read them when you ask questions or build pages.
