What is Claude Desktop?
Claude Desktop is an app you install on your computer that gives you access to Claude — Anthropic's AI assistant. It can help you write documents, analyze files, answer complex questions, and plan projects. Unlike the web version, the desktop app can work with files on your computer more directly.
Think of it as having a very capable research assistant sitting on your desktop, ready to help with any knowledge work.
Quickstart
- Visit claude.ai/download and click the Mac download button.
- Open the downloaded file and drag Claude to your Applications folder.
- Open Claude from your Applications folder (or Spotlight: press
Command + Space, type "Claude"). - Sign in with your Anthropic account (or create one for free).
- Start a conversation — try "Help me write a professional bio" or "Analyze this document" (drag a file into the chat).
Key features
- Chat — Ask questions, get help writing, brainstorm ideas with one of the most capable AI models
- File analysis — Drag PDFs, spreadsheets, or images into the chat to analyze them
- Projects — Create separate spaces for different topics, with persistent instructions and files
- Long conversations — Claude can handle very long documents and detailed discussions
