Most people think Claude Code writes code. It does. But that is like saying a Swiss army knife cuts things. True, but missing the point.

Claude talks to your computer. It can do almost anything your computer can do — not in a theoretical, futuristic sense, but right now, today, on the machine you are reading this on.

Here is a non-exhaustive list of things Claude did on my computer this week:

  • Renamed 400 photos by date, subject, and client
  • Organised a project folder into a clean structure with nested subfolders
  • Built a spreadsheet of image dimensions for a print job
  • Opened three competitor websites in my browser and summarised their visual approach
  • Found every file on my desktop older than 30 days and asked whether to archive or delete each one
  • Created a PowerPoint presentation from a rough outline
  • Tested a portfolio site by clicking through every page and reporting broken links

I did not write any code for any of this. I described what I wanted in plain English.

The three tabs

The Claude desktop app has three modes, each suited to different kinds of computer work.

Code — the builder

The Code tab is for projects that live in a folder. You point it at a directory, and Claude works inside it — creating files, modifying them, running things. This is where you vibe code: build websites, interactive pieces, tools, and prototypes.

If the end result is a file or a set of files, this is your tab.

Cowork — the assistant

The Cowork tab is for everything else on your computer. It can open applications, create documents, organise files, fill spreadsheets, browse the web, and manage tasks — all on your actual machine.

If the end result is a document, an organised folder, or a completed task, this is your tab.

Chat — the thinker

The Chat tab is plain Claude. No file access, no computer control. Just conversation. Use it for brainstorming, quick questions, and drafts where you do not need anything to happen on your machine.

What Cowork can actually do

This is the tab most creatives underuse. Here are real examples.

Organise your files

I have 300 photos on my desktop from last month’s shoot. Organise them into folders by date. Name the folders “2026-03-15 — Studio”, “2026-03-18 — Location” etc, based on the EXIF data. Move any duplicates into a “Duplicates” folder.

Claude reads the photo metadata, creates the folder structure, and moves every file. You watch it happen.

Create documents

Write a project proposal for a branding client. Three sections: scope of work, timeline, and pricing. Use professional formatting. The client is a boutique hotel called The Linden. Scope includes logo, brand guidelines, website design, and photography direction. Timeline is 8 weeks. Pricing is £12,000 total. Save it as a Word document on my desktop.

Claude creates the document with proper formatting, headings, and structure. It lands on your desktop as a .docx file.

Build spreadsheets

Create a spreadsheet of all my portfolio images. Columns: filename, dimensions, file size, colour space, and whether it’s portrait or landscape. Save it as an Excel file.

Claude reads every image in your folder, extracts the metadata, and builds the spreadsheet with working columns.

Clean up your machine

Look at my Downloads folder. Show me everything older than 60 days, grouped by file type. Then ask me what to keep and what to delete.

Claude scans the folder, groups the files, presents a summary, and waits for your decision on each group. No surprises.

Schedule recurring tasks

Every Monday morning at 9am, check my project folders for any files modified in the last week. Create a summary of what changed and put it on my desktop as “Weekly Summary — [date].md”.

Cowork supports scheduled tasks. Set it up once, and it runs automatically.

Computer Use — the screen controller

Beyond files and documents, Claude can actually use your computer the way you do: clicking, typing, scrolling, opening apps. This is called Computer Use and it is available on Mac and Windows.

To enable it: Go to Settings → General in the Claude desktop app. Turn on the Computer Use toggle. On Mac, grant Accessibility and Screen Recording permissions when prompted.

Once enabled, Claude can:

  • Open any app — Photoshop, Figma, your browser, a spreadsheet, anything
  • Click and navigate — scroll through pages, click buttons, fill forms
  • Type into applications — enter text into any field, in any app
  • Take screenshots — capture what it sees and reason about it

Real examples

Test a website in your browser:

Open my portfolio site in Chrome. Click through every link on the page. Tell me if any are broken. Check that every image loads. Take a screenshot of the mobile view.

Claude opens Chrome, navigates to your site, clicks every link, checks the results, and reports back.

Fill in a form:

Open the grant application at [URL]. Fill in my details: name, email, project description. Use the project summary from my proposal document. Don’t submit — just fill everything in and let me review.

Claude opens the browser, navigates to the page, fills in each field, and stops before the submit button.

Interact with a design tool:

Open the mood board in Figma. Take a screenshot. Describe the colour palette and typography you see. Then build a web page that matches that aesthetic.

Claude takes a screenshot, analyses the visual style, and uses that understanding to build something that matches.

What Computer Use cannot do

It cannot interact with browsers freely (it can view but not type in browser windows — this protects you from accidental form submissions). It cannot bypass your permission for each app. And it requires the desktop app to be running.

For browser automation specifically, there is an even better option: Claude in Chrome, an extension that gives Claude direct access to your browser with full awareness of the page structure. This is more precise than Computer Use for web-based tasks.

The mental model

Here is the thing that makes all of this click:

Your computer is already capable of everything. Claude just gives it a voice interface.

You have always been able to rename 400 files. It just required knowing Terminal commands, or dragging files one by one. You have always been able to build a spreadsheet from image metadata. It just required knowing Excel formulas and a file-reading script.

Claude removes the “knowing how” barrier. You describe the outcome. Claude figures out the method. Your computer does the work.

This is why vibe coding works — and it is also why Claude’s usefulness extends far beyond code. Every task on your computer that can be described in words can be delegated to Claude.

Getting started

Pick one real task from your week — something tedious, repetitive, or just annoying — and try it.

If it involves files in a project folder: Open the Code tab, select the folder, describe the task.

If it involves documents, organisation, or apps: Open the Cowork tab, describe the task.

If you just want to think something through: Open the Chat tab, have the conversation.

Start small. “Rename these files.” “Create a summary of this folder.” “Build me a spreadsheet.” Watch Claude work. Then go bigger.
