Claude
Claude is Anthropic's conversational AI assistant for writing, coding, research, and analysis. You chat with it on the web at claude.ai, through desktop and mobile apps, or through the Claude API if you are building your own product.
The product goes well beyond a chat box. Claude Code handles agentic coding, Claude Cowork runs delegated tasks across your apps, and dedicated workflows cover design and scientific research. The model lineup includes Fable, Opus, Sonnet, and Haiku, with extended thinking for harder problems and memory that carries across conversations.
It fits developers, researchers, writers, and teams who want one assistant to brainstorm, draft, analyze data, run code, and plug into Slack, Google Workspace, or Microsoft 365 through connectors and desktop extensions.
