Chat, Cowork & Code — The Three Ways to Use Claude

Most people only ever meet one Claude: the chat box at claude.ai. But there are three different ways to work with Claude, and knowing which one to reach for is the difference between "a smarter Google" and "a coworker who actually does the task."

Here's the map. You'll spend Module 1 in the first one and graduate to the second in Module 2.

1. Chat — Claude that answers

This is claude.ai (and the mobile app): a conversation. You ask, Claude responds. You can paste in text, upload a file for it to read, and have a long back-and-forth.

• Great for: writing, thinking, research, explaining, drafting, analyzing something you paste or upload.
• The limit: Claude can read what you give it and write a response, but it can't reach into your computer and actually do things. It can write the email — it can't open your files, edit the spreadsheet, and save it back.
• Cost: there's a free tier. This is where everyone starts, and it's the whole of Module 1.

Think of Chat as talking to a brilliant expert across a desk. They'll tell you exactly what to do. You still have to go and do it.

2. Cowork — Claude that does the work

Cowork is a mode in the Claude desktop app (it sits next to Chat and Code). Instead of just answering, you give it a goal and point it at folders on your computer. It can then read, edit, and create files in those folders, use connected tools, and work through a multi-step task on its own until there's a finished result — checking in with you before it does anything significant.

• Great for: real knowledge work — turning a folder of notes into a report, cleaning up a spreadsheet, reorganizing files, drafting a deck from source material, running a repeatable workflow across your own documents.
• The shift: you stop copy-pasting. Claude works on your actual files, not on text you ferry in and out by hand.
• Requirements: a paid Claude plan and the desktop app (macOS or Windows). This is the productivity end-goal — all of Module 2.

Think of Cowork as hiring that expert as a coworker and giving them a desk next to yours. You hand them the task; they do it and hand it back.

3. Code — Claude that builds software

Claude Code is a version of that same agentic Claude built for developers, running in your terminal. It reads, writes, and runs the actual files of a software project.

• Great for: building and shipping real apps, websites, tools, and automations.
• Requirements: a paid plan; you install it on your computer (we set this up in Module 3).
• This is the whole Builder track (Modules 3–7) and beyond.

Cowork and Code are the same engine — agentic Claude that works on real files and tools. Cowork wears a friendly, no-terminal interface for everyday work; Code is the developer's tool. Many people never need Code at all.

Which one should I use?

A simple rule of thumb: if you'd end the conversation by copy-pasting Claude's answer somewhere and doing the work yourself, you've outgrown Chat — that task belongs in Cowork.

Where this course takes you

• Module 1 (you're here): master Chat — prompting, getting good answers, working with what you paste in.
• Module 2: graduate to Cowork — Claude that works your real files, folders, and tools end-to-end. This is the Productivity Finish Line.
• Modules 3+: if you want to build software, step up to Code.

The exact names and menus can shift — Anthropic ships fast. The three roles are the stable idea: a Claude that answers, a Claude that does your work, and a Claude that builds.

Summary

• Chat (claude.ai): answers, drafts, analyzes what you give it. Free. Module 1.
• Cowork (desktop app): an agentic coworker that reads, edits, and creates real files and uses your tools to finish tasks. Paid + desktop. Module 2 — the productivity end-goal.
• Code (terminal): the same agent, built for developers to ship software. Modules 3+.
• Rule of thumb: the moment you'd copy-paste an answer and go do the work yourself, that task belongs in Cowork.
