Anthropic offers two distinct agentic AI systems: Claude Code and Claude Cowork. Claude Code is an agentic coding system that allows developers to delegate substantial engineering tasks directly from their terminal. It can read and understand entire codebases, make changes across multiple files, write and run tests, commit and push code to GitHub, and use command-line tools. It's designed to accelerate development, facilitate large-scale refactoring, and democratize software building for individuals without extensive engineering backgrounds. Claude Cowork is an agentic AI for general knowledge work, designed for non-technical users. It operates on your desktop, interacting with local files, folders, and applications to autonomously complete multi-step tasks. Users can assign goals in plain language, and Claude Cowork will organize files, prepare documents from source materials, synthesize complex research, and extract data from unstructured files. Both systems aim to reduce manual effort, improve efficiency, and allow users to focus on higher-level strategic thinking and decision-making.
