Cowork is best for end-to-end work: read your actual files, make decisions, write output, save it back. ChatGPT is a smart notepad. Cowork is a co-worker with file and app access.
Cost model
ChatGPT Pro is $20/month. Cowork is included with Claude Pro ($20/month). Both cost the same. The difference is not price; it is where the work lives — ChatGPT stays in the browser, Cowork touches your real files and apps.
