What is Claude Cowork?

Most AI tools are conversational. You ask a question in a chat window, you get an answer back, and the work of turning that answer into something—a deck, a doc, a spreadsheet, a sent email—is still yours.

Claude Cowork (opens in new tab) is built for the work, not just the answer. It's a version of Claude that reads and writes files on your computer, uses your connected work apps, and runs multi-step tasks on your behalf. You describe an outcome ("build me a quarterly planning deck," "compare these five vendor proposals"), Claude plans the steps, executes them, and delivers something tangible across your files and tools.

In practice, this looks like:

• Hours back in your week, because Claude tackles the context-gathering and tedious work that you'd usually skip or push off.
• Decisions grounded in everything relevant, not just the three tabs you happened to have open.
• Polished output you can trust, with citations back to the real files and messages instead of plausible-sounding text assembled from nothing.
• A shorter distance between "I need to do this" and "it's done," especially for the recurring work — weekly updates, meeting prep, catch-ups, triage — that never quite justifies its own tool.

This guide is for analysts, PMs, operators, researchers, marketers, recruiters, and anyone else whose day is spent moving information between systems. By the end, you'll have a working understanding of Claude Cowork, six workflows to try today, and pointers for going deeper.
