Introducing Cowork: Claude Code for the rest of your work.

Available as a research preview for Max users on macOS, the agent can both handle your files and create new ones.
Based on Claude Code users surprising their developers, using the tool to manipulate local files — Anthropic is now launching an app that does just that.
Office computer user
Cowork works by giving the app access to a folder, and from there it can make an expense spreadsheet from a collection of receipts, create a draft report from scattered text files, or organize or rename files in the folder.
It can even access Google Calendar and review meeting notes for you.
You access the tool in natural language, and it provides a list of tasks so you can keep an eye on it and approve each action.
Comes with warnings
It does come with a couple of warnings. First, Anthropic wants you to be super precise when prompting Cowork, as it could possibly delete files if you aren’t careful.
Secondly, agents like this are vulnerable to prompt injection attacks that may lurk in files downloaded from the internet — so to be extra safe, the folders should only contain trusted files.
Next up for the tool is gathering user data and input, and launching a Windows app at some stage. It might even get a wider release at some point, as well.
