Curated lists that include this category
ChatGPT is OpenAI’s assistant for writing, research, analysis and other tasks described in ordinary language. Its current interface offers Chat for conversation, Work for tasks that need several steps and a finished result, and Codex for software work with developer tools. OpenAI explains these differences in its ChatGPT usage guide.
How to use it
For a writing task, provide the audience, source material and desired format, then revise the draft through follow-up requests. For research, give a question and ask for linked sources and unresolved gaps. Work can use files, browse websites and produce documents, presentations, spreadsheets or PDFs; projects keep related material together. Connected plugins can bring in services such as Google Drive, GitHub or Slack. See the web app guide for these workflows.
Plans and access
A Free plan is available. The listed USD monthly rates are US$8 for Go, US$20 for Plus, and US$100, US$200 or US$500 for Pro options. Check your account checkout for regional pricing and availability; organizational plans have separate billing. Work and Codex share usage, while API-key requests follow separate API billing. Check the official pricing and usage page for the account you intend to use.
What to check before relying on it
Model choices and tools depend on your plan, device, region, rollout and workspace settings. Cloud work runs in a managed environment; supported desktop local work can use your computer’s files and tools. That distinction concerns where tasks execute and does not make ChatGPT an offline model download. The usage guide recommends reviewing results and consequential actions. In practice, check citations, calculations and generated files before sharing them.
