How to Set Up Claude Desktop for Your Small Business

Claude Desktop is Anthropic's standalone AI assistant app. While claude.ai offers many of the same features in the browser, the desktop app adds Cowork mode — a feature that lets Claude work on tasks while you continue using other apps. You also get tighter file access and a native macOS experience.

This guide walks you through setting up Claude Desktop on macOS and organizing your first business project.

What You Get With Claude Desktop

Before we install, here's why the desktop app matters for your business:

• Projects — Group related conversations by client, department, or initiative. Add files and instructions that persist across every chat in that project.
• Cowork Mode — Hand Claude a task and let it work while you switch to other apps. The Claude Desktop app needs to stay open, but you can keep working — check back when it's done. Great for drafting emails, summarizing documents, or researching competitors.
• File Access — Drag files directly into conversations. Claude can read PDFs, spreadsheets, images, and code files.
• MCP Integration — Connect Claude to external tools like your file system, databases, or APIs using the Model Context Protocol.

Step 1: Download and Install

1. Go to claude.com/download
2. Click Download for macOS
3. Open the .dmg file and drag Claude to your Applications folder
4. Launch Claude from your Applications folder or Spotlight (Cmd + Space, type "Claude")

On first launch, you'll be asked to sign in with your Anthropic account. If you don't have one, create it — it takes 30 seconds.

Step 2: Create Your First Project

Projects are how you organize work in Claude Desktop. Think of them as folders that give Claude context about what you're working on.

1. Click the Projects icon in the sidebar
2. Click + New Project
3. Give it a name (e.g., "Q1 Marketing Plan" or "Client Onboarding")
4. Open Project Instructions (in the project settings) — this is where you give Claude persistent context that applies to every conversation in the project

Here's an example set of project instructions for a small law firm:

This project is for Smith & Associates, a 3-attorney personal injury firm.
We're exploring AI tools to improve client intake and reduce missed calls.
Budget: $500-2,000/month for AI tools.
Key concerns: HIPAA-adjacent data handling, client confidentiality.

Every conversation you start inside this project will have these instructions as context automatically. No need to re-explain your situation each time.

Step 3: Add Project Knowledge

You can attach files to a project that Claude can reference in any conversation within it:

1. Open your project
2. Click Add Content or drag files into the project panel
3. Supported formats: PDF, Word docs, text files, images, spreadsheets

What to add:

• Your business plan or one-pager
• Service descriptions or pricing sheets
• Client intake forms or templates
• Competitor research you've gathered

Step 4: Set Up Cowork Mode

Cowork is the killer feature for business owners. It lets you give Claude a task and walk away.

1. Start a conversation in your project
2. Click the Cowork tab in the conversation
3. Describe your task clearly
4. Claude works on it while you switch to other apps — you'll see a notification when it's done (keep Claude Desktop open)

Good Cowork tasks for small businesses:

• "Draft 5 follow-up email templates for leads who didn't respond"
• "Summarize this 40-page contract and flag any concerning clauses"
• "Research the top 10 AI chatbot platforms for customer service and compare pricing"
• "Create a weekly social media content calendar for March"

Step 5: Customize with Personal Preferences

You can set preferences that apply to every conversation across all projects:

1. Click your profile icon (bottom-left)
2. Select Settings
3. Navigate to Profile
4. Add instructions about your communication preferences

Example instructions for a business owner:

I run a small dental practice with 12 employees. When I ask about AI tools,
prioritize solutions that are HIPAA-compliant and cost under $200/month.
Keep explanations non-technical — I'm not a developer. Always include
estimated setup time and ongoing costs.

Tips for Getting the Most Out of Claude Desktop

Be Specific With Your Requests

Instead of "Help me with marketing," try:

I need to write a Google Business Profile post about our new
teeth whitening service. Keep it under 100 words. Include a
call-to-action for booking. Tone: friendly and professional.

Use Projects for Different Contexts

Create separate projects for:

• Each major client or account
• Internal operations vs. client-facing work
• Research vs. content creation

Combine Cowork With File Uploads

Upload a document, then use Cowork to process it:

1. Upload your Q4 financial report (PDF)
2. Enable Cowork
3. Ask: "Analyze this report. Create a summary with key metrics, trends, and 3 actionable recommendations for Q1"

What's Next

Now that Claude Desktop is set up, you're ready to start using AI in your daily workflow. Here are some natural next steps:

• Prompt engineering — Learn how to write prompts that get better results (coming soon)
• Workflow automation — Connect Claude to your existing tools with n8n (coming soon)
• AI policy — Create an AI usage policy for your team (coming soon)

The key is to start small. Pick one repetitive task — responding to common client questions, drafting weekly reports, or researching vendors — and use Claude Desktop to handle it this week.
