Claude is the model the most demanding users keep open in a second tab. Best-in-class for coding, long-context reasoning, and writing quality.
Claude is Anthropic's flagship AI assistant. Best-in-class for coding, complex reasoning, and writing quality. The model the most demanding users keep open in a second tab.
What it does
Claude is a general-purpose AI assistant available on web, mobile, desktop, and API. It writes code, analyzes documents, drafts strategy, processes spreadsheets, generates images, and increasingly operates as an autonomous agent through Anthropic Computer Use and the Claude Code CLI.
The product anchor differs from ChatGPT. ChatGPT optimizes for consumer breadth. Claude optimizes for the tasks that need to be right. That positioning has made Claude the default model for software engineering, legal review, financial analysis, and any other workflow where output quality matters more than novelty.
Anthropic also defined the Model Context Protocol — the standard now connecting AI models to external tools and data across the industry. That makes Claude the AI model with the strongest native agentic stack: MCP for tool use, Anthropic Computer Use for screen control, Claude Code for software engineering.
