Your recommendation
Sonnet 5 — the workhorse default — fast, strong, and economical for everyday professional work, and the model claude.ai now starts you on — with a 1M-token context window. On claude.ai, leave the model on Sonnet 5 (the default), and switch to Opus 5 for the deliverables that matter.
Pro — $20/mo ($17/mo billed annually). Start on the Free tier (Sonnet 5 plus limited Haiku) just to try it.
Claude Cowork is included on every plan — even Free — but installing plugins needs a paid plan (Pro, Max, or Team). The Free tier (Sonnet 5 + limited Haiku) is fine for trying Claude before you upgrade.

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.
Do the paid prompt packs work with ChatGPT?
Yes — the packs are written and tested for Claude, and every pack 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.
