About Claude

Claude is Anthropic's AI assistant, built for thoughtful writing, coding, analysis, and long-context research. It pairs strong reasoning with a clean, conversation-first interface, and handles everything from quick questions to large documents and entire codebases.

We keep Claude in the daily rotation for drafting, refactoring, and thinking through problems out loud. The desktop app makes it instantly reachable with a global shortcut instead of living in a browser tab.

Try Claude yourself.

Open it in the browser, or grab the desktop app.
