What is Claude?

Claude is an AI assistant and large language model developed by Anthropic that helps individuals and teams work faster and more accurately across writing, coding, research, analysis, and creative tasks. It sits at the intersection of AI chatbots, natural-language-understanding, coding assistants, and enterprise-ready large language models, giving you a single space to think, build, and collaborate with AI. Users rely on Claude to draft and edit documents, generate and review code, analyze data, reason about complex topics, and interact with text and images in a natural conversational interface.

Claude is available through a web app, desktop app, mobile apps, and an API, with plans ranging from a Free tier for personal use up to Team and Enterprise offerings for organizations that need more usage, control, and security. Anthropic is an AI research company headquartered in San Francisco, and Claude is its flagship product for developers, knowledge workers, and businesses that want a safe, steerable AI assistant rather than a general-purpose black box.

Claude began as a next-generation chatbot focused on being helpful, honest, and harmless, grounded in Anthropic’s Constitutional AI research. Over time it has evolved from a single conversational interface into a broader platform with multiple models - including Fable, Opus, Sonnet, and Haiku - and specialized tools like Claude Code, Claude Cowork, Claude Design, and Claude Science. Today, Claude combines fast chat, long-context reasoning, coding and data analysis, and integrations into productivity suites and developer workflows, while continuing to prioritize safety and reliability.
