Get started with Claude Cowork for everyday office tasks

The problem

You have piles of unorganised files, scattered notes that need turning into reports, or tedious document tasks that consume hours. Claude chat is helpful, but you're constantly copying and pasting content back and forth. You want AI that can actually work with your files directly - reading, creating, and editing documents in your folders - but you're not a developer and can't use coding tools.

The solution

Use Claude Cowork, Anthropic's new agent that works directly with files on your computer. Give Claude access to a specific folder, describe what you need ('organise these expense receipts into a spreadsheet' or 'turn my scattered notes into a draft report'), and Claude plans and executes the task autonomously. It reads, edits, and creates files while keeping you updated on progress. Think of it as Claude Code for non-coders.

What you get

Completed file-based tasks: organised folders, compiled reports from scattered notes, spreadsheets created from receipt images, cleaned-up data files. Claude works directly in your file system, creating outputs you can immediately use. No copy-pasting between chat and documents.

Before you start

• Claude Max subscription (£80-160/month) - this is a premium feature with significant cost
• Mac computer (Windows/Linux not yet supported as of January 2026)
• Claude Desktop app installed
• A folder of files you want Claude to work with
• IMPORTANT: Check your data protection policy before use. Cowork sends file contents to Anthropic (US-based) for processing. Do not use with files containing personal data about beneficiaries or staff without appropriate safeguards.

When to use this

• You have file organisation tasks that would take hours manually
• You need to compile reports from scattered documents
• You want to process batches of files (receipts, notes, data) into structured outputs
• You're comfortable with AI having access to a designated folder

When not to use this

• You're on Windows or Linux (not yet supported)
• You don't have a Claude Max subscription
• The files contain highly sensitive data (start with low-risk tasks)
• You need precise, deterministic outputs (AI may interpret tasks differently than intended)
• The cost isn't justified for your organisation's needs

Steps

1. 1

   Check requirements

   Verify you have: Mac computer, Claude Max subscription (£80-160/month), Claude Desktop app installed. Cowork is a research preview feature that may have limited availability.

2. 2

   Create a dedicated work folder

   Create a new folder specifically for Claude to work in (e.g., ~/Documents/Claude-Work). Copy the files you want processed into this folder. Don't give Claude access to your entire Documents folder - start contained.

3. 3

   Enable Cowork and grant folder access

   In Claude Desktop, enable Cowork from Settings. When prompted, grant access to your designated work folder. Claude can only read and modify files you explicitly give it access to.

4. 4

   Start with a simple task

   Begin with something low-risk: "Look at the files in this folder and tell me what's there" or "Rename these files to include the date from their contents." Verify Claude understands your folder before giving it complex tasks.

5. 5

   Describe your task clearly

   Give Claude a clear objective: "Create a spreadsheet summarising all the expense receipts in this folder. Include date, vendor, amount, and category." Claude will plan the approach and execute it step by step, updating you on progress.

6. 6

   Review and guide

   Watch Claude's progress updates. If it's going in the wrong direction, you can intervene and redirect. Remember: Claude may delete or modify files, so work with copies of important documents until you're confident.

7. 7

   Verify outputs

   Check the files Claude created or modified. Look for accuracy, especially with numbers or important details. AI can make mistakes - treat outputs as first drafts that need human review.

8. 8

   Extend with browser integration (optional)

   Install the Claude Chrome extension to let Cowork navigate websites as part of tasks. This enables tasks like "research these organisations and add notes to my spreadsheet." Only do this for tasks where you're comfortable with automated web browsing.

Example code

# Good Cowork tasks for charity work

## Expense processing
"I have 30 receipt photos in this folder. Create an Excel spreadsheet with columns for: date, vendor, amount, category (travel/supplies/food/other). Name it expenses-january-2026.xlsx"

## Report compilation
"I have meeting notes from the last quarter (the .docx files in this folder). Create a summary document highlighting: key decisions made, actions assigned, and recurring themes. Save as Q4-meetings-summary.docx"

## File organisation
"Organise the files in this folder into subfolders by year based on the date in each filename or document content. Create a log.txt listing what you moved where."

## Data extraction
"Read through these grant application PDFs and create a spreadsheet comparing: funder name, deadline, amount available, our eligibility, and key requirements."

## Content repurposing
"Take the annual report PDF in this folder and create three separate documents: 1) A 2-page summary for trustees, 2) Key statistics as a one-pager, 3) Impact stories extracted as individual case studies."

# Tasks to be careful with

## High-risk (work with copies first):
- Anything modifying important original files
- Tasks involving sensitive data
- Reorganising folders you can't easily restore

## Better done differently:
- Tasks requiring precise formatting (use copy-paste workflow)
- Highly confidential documents (don't give Claude access)
- Tasks where errors have significant consequences

# Using Cowork safely

## Before you start
1. Work with COPIES of files, not originals
2. Use a dedicated folder, not your main Documents
3. Remove any files containing personal data
4. Have a backup of anything important

## What Cowork CAN do
- Read files you give it access to
- Create new files in your folders
- Edit and rename existing files
- Delete files (be careful!)
- Browse websites (with Chrome extension)

## What to keep away from Cowork
- Files with beneficiary personal data
- Confidential HR or financial documents
- Files you can't afford to lose or have modified
- Anything with passwords or credentials

## If something goes wrong
- Claude may misinterpret instructions
- Files may be modified unexpectedly
- Outputs may contain errors
- You can interrupt tasks in progress

## Recommended approach
1. Start with throwaway test files
2. Graduate to copies of real files
3. Only work with originals when confident
4. Always verify outputs before use
