What is Codex?
Codex is an AI work partner built into ChatGPT and developer tools. Unlike everyday chat, Codex takes a job end-to-end: understand your materials, plan the work, create files (HTML, PDF, PPT, scripts, code), run commands, check results, and revise when you ask.
Two ways to work together. Cloud Codex runs in your browser — connect GitHub or upload context, delegate tasks, get pull requests or downloadable outputs. Local Codex runs in VS Code, Cursor, or Windsurf with access to your folders and terminal — ideal when your files live on your machine.

|---|---|---|

| Typical output | PR, files, exports | Edited files & exports |
| Who uses it | Anyone with ChatGPT | Power users & developers |

How Codex helps
More than answers — finished work
Tell Codex what “done” looks like. It figures out the steps, produces deliverables, and stays with you until the result matches your brief.
Understands the brief
Explain outcomes in everyday language — structure, tone, data sources, and what success looks like. No jargon required.
Delivers real files
HTML slide decks, PDF exports, cleaned CSVs, scripts, docs, and code — not just suggestions in a chat window.
Works until it's right
Ask for changes: swap Q2 for Q3, tighten the summary, fix a chart. Codex revises the work, not just the advice.
Data & research
Summarize surveys, join spreadsheets, spot trends, and turn raw inputs into insight-ready tables and narratives.
Pages & presentations
Generate on-brand HTML slides, then export to PDF or PPT — a solid first draft you can polish or present.
Free to start
Core Codex access is on ChatGPT's free plan — try a real work partner without a paid subscription.

Working with Codex — FAQ
Independent guide — not affiliated with OpenAI.
Do I need to know how to code?
No. Describe outcomes in plain language — “make a PDF report from this CSV.” Codex handles scripts and files behind the scenes. Developers can go deeper; everyone else can stay at the goal level.
Can Codex make slides or PDFs?
Yes. A common flow: Codex builds structured HTML slides with your styles, then exports PDF or generates PPTX. You review and ask for revisions like any collaborator.
How is Codex different from ChatGPT chat?
ChatGPT excels at conversation and drafts. Codex is oriented toward completion — it creates files, runs workflows, and iterates until the deliverable matches your brief.
Is Codex really free?
Yes — Codex is included in ChatGPT's free plan with usage limits. Paid plans offer higher limits. This site helps you get started.
What tasks work best?
Clear goals with concrete deliverables: a report, a cleaned dataset, a slide deck, a page, a batch of listings. The more specific your brief, the better your partner performs.
