A practical guide to getting started with Anthropic’s desktop AI agent.

Last verified: March 2026

Prerequisites

• Claude Pro, Team, or Enterprise subscription ($20+/month)
• Claude desktop app (Mac or Windows)
• Files and folders you want Cowork to work with

Getting Started

Step 1: Open Cowork

In the Claude desktop app, look for the Cowork option in the sidebar or start a new conversation and switch to Cowork mode.

Step 2: Describe Your Task

Be specific. Instead of “organize my files,” try:

“Sort all PDF files in my Downloads folder into subfolders by year based on their creation date. Create folders named 2024, 2025, and 2026.”

Step 3: Review the Plan

Cowork will show you a step-by-step plan before executing. Review it carefully:

• Are the right files targeted?
• Is the destination correct?
• Does the logic make sense?

Step 4: Approve and Monitor

Click approve to let Cowork execute. Watch the progress — you can pause or cancel at any time.

Step 5: Verify Results

Always check the output, especially for the first few tasks. Cowork is reliable for structured tasks but can make mistakes with ambiguous instructions.

Best Tasks for Cowork

Task	Reliability	Notes
File organization	⭐⭐⭐⭐⭐	Sorting, renaming, moving files
Report generation	⭐⭐⭐⭐	From structured data inputs
Document formatting	⭐⭐⭐⭐	Reformatting spreadsheets, text
Data extraction	⭐⭐⭐⭐	Pulling info from multiple files
Creative work	⭐⭐⭐	Drafts are good, needs human review
Complex multi-step	⭐⭐⭐	Break into smaller tasks

Tips for Better Results

1. Be specific — Include file paths, formats, and expected outputs
2. Start small — Test with a few files before running on your whole drive
3. Use examples — “Format it like this: [example]” works well
4. Break complex tasks — Multiple small Cowork sessions > one giant task
5. Keep backups — Until you trust the workflow, maintain copies

Common Mistakes

• ❌ Vague instructions (“make it better”)
• ❌ Running on critical files without backup
• ❌ Skipping plan review
• ❌ Expecting it to handle ambiguous decisions
• ✅ Clear, specific, measurable instructions
