Claude Cowork or Claude Code?
Anthropic has two tools that actually do work rather than just answer questions, and because the names are similar they get mixed up constantly. Both can touch your files, both plan a task and work through it step by step. The difference is who they were built for.
Short answer: if you work in marketing, it’s Cowork.
What each one does
Claude Cowork is the office-work side. It reads a folder you’ve granted access to on your machine, edits files, and produces deliverables — Excel spreadsheets with working formulas, PowerPoint decks, formatted documents. One of the examples Anthropic leads with is squarely our work: pulling data from several sources into a weekly marketing report with period-over-period comparison.
Claude Code is a software development tool. It reads your codebase, edits files, runs commands, commits to git and opens pull requests. It runs in the terminal, as an IDE extension, in a desktop app and in the browser.
Side by side
| Cowork | Code | |
|---|---|---|
| Built for | Marketing, sales, legal, finance | Software development |
| Where it runs | The Claude app — pick “Cowork” in the message box | Terminal, VS Code, JetBrains, desktop, web |
| Setup | Open the app | Install from the command line |
| Typical output | Spreadsheets, decks, reports, tidied folders | Code, commits, pull requests |
| Technical knowledge | Not required | Terminal and git |
| Platforms | macOS, Windows, Linux, ChromeOS, web, mobile (beta) | Terminal, IDE, desktop, web |
Both need a paid plan: Pro, Max, Team or Enterprise.
What Cowork does for a marketer
The tasks Anthropic and users highlight map directly onto an agency’s weekly routine:
- Pulling data from several sources into a period-over-period report
- Building a spreadsheet out of screenshots or scattered notes
- Comparing contracts or proposals against a checklist and writing up the differences
- Reading call notes to surface deal status and recurring objections
- Reorganising folders and normalising file naming
One detail worth knowing: tasks keep running after you close the laptop, and they can be scheduled. You can start something at your desk and check it from your phone.
The permissions side — where to actually look
Because Cowork reaches into files on your machine, the permission model matters. There are three modes:
- Manual — waits for your approval on each action
- Auto — decides for itself while reviewing for safety issues
- Skip — acts without stopping
If you handle client data, stay in manual mode at first. Claude only reaches the folders you grant, not your whole disk.
Which to choose
Choose Cowork if you produce reports, decks, spreadsheets and documents; if you don’t want to use a terminal; if your work lives in files and folders.
Choose Code if you edit your site’s code, work with GitHub, or want scripts written.
I use both, for different things: Code for site development and automation scripts, the Cowork way of working for client reports and documents. I described my own stack in a separate piece.
Frequently Asked Questions
Do I need to know how to code to use Cowork?
No. You describe the task in plain language; the tool works out a plan, executes the steps, and shows you which files it opened and what it decided.
Does my data go to Anthropic’s servers?
Cowork runs some steps in an isolated environment, so content is processed off your machine. For contracts, client lists and similar sensitive files, read your plan’s data policy before you start.
Can I use it on the free plan?
No, it needs a paid plan (Pro, Max, Team, Enterprise). It also consumes more of your usage allowance than ordinary chat.
Is there a ChatGPT equivalent?
There are tools with similar aims, but not an exact match. I covered the comparison on the Claude or ChatGPT page.
Does my chat memory carry over into Cowork?
Not unless you’re working inside a project. You may need to restate the context you gave in chat when you open a Cowork session.
