Claude Desktop App: Complete Setup Guide for Business Owners
Most people access Claude through their browser, but the desktop app is a completely different experience. It gives you access to three distinct modes - Chat, Cowork, and Code - each built for different kinds of work. If you're a business owner who wants to get serious about using Claude as a daily work tool, the desktop app is where you start. This guide walks you through every step of getting it set up and ready to use.
Why Use the Desktop App Instead of the Browser?
The browser version of Claude is great for quick questions and one-off tasks. The desktop app is built for deeper work. It integrates directly with your computer's file system, runs scheduled tasks in the background, connects to your local apps, and gives you persistent workspaces that stay organised across sessions. For business owners using Claude as a daily work tool rather than an occasional assistant, the desktop app is significantly more capable than the browser.
Step 1: Download the Claude Desktop App
Go to claude.ai and look for the Download link in the navigation menu or footer. The app is available for both Mac and Windows. Download the installer for your operating system and run it. The installation takes less than two minutes. Once installed, open the app and sign in with the same account you use for claude.ai - your Projects, conversation history, and settings will all carry over automatically.
Step 2: Understanding the Three Modes
When you open the desktop app you'll notice it works differently from the browser. There are three distinct modes accessible from the interface. Chat mode works exactly like the browser version - you have a conversation, ask questions, get responses. This is your starting point for writing, research, and thinking tasks. Cowork mode is a workspace for running scheduled tasks, automations, and ongoing projects that Claude manages on your behalf. Code mode is designed specifically for software development tasks and working directly with codebases. Most business owners will spend the majority of their time in Chat and Cowork.
Step 3: Setting Up Your Prompt Interface
The prompt interface in the desktop app has more options than the browser version. You'll notice options to attach files, add context from your local system, use skills, and connect to external services. Take a few minutes to explore these before diving into work. The interface is designed to be intuitive, but understanding what each button does upfront saves time later. The attachment button lets you pull in documents, images, and spreadsheets directly from your computer without having to drag and drop.
Step 4: Granting Local File Permissions
One of the desktop app's most powerful features is the ability to read and organise files directly from your computer. To enable this, you need to grant Claude permission to access specific folders. In the app settings, look for the Files or Permissions section and grant access to the folders you want Claude to be able to read - typically your Documents folder, your Downloads folder, or a specific project folder. Claude will never modify or delete your files without explicit instruction - it reads them to help you work with them.
Step 5: Exploring Skills and Connectors
Skills are reusable instruction sets that teach Claude how to perform specific tasks in your specific way. Connectors are integrations that link Claude to external services like Gmail, Google Calendar, Airtable, and more. Both are accessible from the desktop app interface. In the settings or sidebar, look for Skills and Connectors sections. Start by browsing the pre-built options before creating custom ones - there are templates for common business tasks that work well out of the box and give you a sense of what's possible.
You're Ready to Start
With the desktop app downloaded, your modes understood, file permissions granted, and a first look at skills and connectors completed, you're set up to use Claude properly. The next step is connecting your most-used tools - starting with Gmail and Google Calendar - and building your first automated workflow.
