Claude Cowork vs Code vs Design

The decision tree. 12 common tasks mapped to the right Claude surface.

Tested April 2026.

Claude decision tree comparing 12 common tasks against the four Claude surfaces — Chat, Cowork, Code, and Design. Two Chat tasks (fact-checking, brainstorming Substack titles), three Cowork tasks (sorting receipts, updating Notion from PDFs, scheduling weekly digests), three Code tasks (refactoring repos, migrating Python to Go, writing CI workflows), and four Design tasks (pitch decks, Gumroad one-pagers, landing page hero prototypes, slider-based deck refinement). Tested April 2026.

Claude is now four products sharing one model family: Chat, Cowork, Code, and Design. Pick by task, not by name. The table below maps 12 common knowledge-work and developer tasks to the right surface, with one sentence on why.
