The familiar ChatGPT experience and the full power of Codex now in one app. Use Chat to ask questions, think through possibilities, and make sense of topics through conversation. Ask questions, get clear explanations, and follow your curiosity through conversation. Turn a rough thought into stronger ideas you can explore and refine. Understand the tradeoffs, choose a direction, and turn it into practical next steps. Use ChatGPT Work to turn a goal, files, and context into documents, spreadsheets, presentations, and other useful deliverables. Bring together files and sources, then turn the important details into a clear point of view. Find patterns, compare evidence, and surface the insights that matter. Turn your source material into polished work you can review, share, and keep refining. Build anything. Use Codex to understand codebases, build and test features, fix bugs, and review changes. Understand how a project is structured, find the important files, and get oriented quickly. Turn an idea or issue into a working change, then iterate on the result. Make focused changes, run checks, review the diff, and get the work ready to ship. What will you do with ChatGPT? Start with a workflow, a deliverable, or something you want to build. Get your email to inbox zero Clear the backlog, draft replies in your voice, and stay on top of new email. Use your computer with ChatGPT Let ChatGPT click, type, and navigate apps on your macOS or Windows computer. Give Codex a durable objective for long-running work.
