Chat, Cowork, Claude Code, or Chrome?

Use Claude chat
Your inputs are things you can paste or upload and you want an answer or a draft back — that is exactly what chat is for, and it is the only surface on the Free plan.
Ask and answer, drafting, and analysis of whatever you paste or upload. The surface you already know.
The moment the job becomes 'do this across my files' rather than 'answer this', Cowork is the surface for it. Paid plans only.
Surface availability verified August 2026. Anthropic ships fast — check claude.com/pricing if something looks out of date.
Common questions
Does this tool work with ChatGPT?
The tool itself runs on Claude (Anthropic) right here on the page — you don't need any AI subscription to use it. Everything it generates is plain text, so you can paste the output into ChatGPT, a document, or an email and keep working there. If you mainly work in ChatGPT, you can also reuse your inputs there to refine further.
What AI model powers this tool and the example output?
Claude, Anthropic's AI. The example outputs shown on tool pages were generated with Claude.
Does the paid AI Operating System work with ChatGPT?
Yes — each AI Operating System is written and tested for Claude, and every one includes a portable prompts-only set that works in ChatGPT and Gemini (copy and paste, occasionally with a minor tweak). The Cowork plugin editions specifically require a paid Claude plan.
Claude is a product of Anthropic. The AI Career Lab is not affiliated with Anthropic or OpenAI.
