What Is Claude?
Discover what Claude is, the principles that guide its design, its core capabilities beyond simple chatbots, and the different ways you can access it across web, desktop, and mobile.
More Than a Chatbot — Your AI Thinking Partner
Claude is an AI assistant built by Anthropic that goes far beyond answering simple questions. Guided by a Constitutional AI framework designed to be helpful, harmless, and honest, Claude functions as a collaborative thinking partner for writing, research, coding, analysis, and complex problem-solving.
Unlike basic chatbots that produce generic responses, Claude is highly steerable — you can direct its personality, tone, and behavior to match your exact needs with minimal effort. This makes it a genuine work collaborator rather than a simple question-and-answer tool.
