Claude AI

Claude is the AI assistant developed by Anthropic. Available on the web at claude.ai, on desktop and mobile, it is designed to support everyday tasks as well as complex professional work.

Claude can write and revise content, analyze long documents, understand images, generate code, visualize data, create files, and help structure research or projects. Web search is built into the Claude experience. Paid plans also provide Research mode, which performs several searches and returns a summary with verifiable citations.

Anthropic’s current model family includes Claude Fable 5, Claude Opus 5, Claude Sonnet 5 and Claude Haiku 4.5. Claude Sonnet 5 is designed to balance speed and intelligence, while Claude Opus 5 is aimed in particular at agentic tasks, advanced reasoning, complex software development and professional workflows. Access to each model depends on the plan and platform.

Claude also includes productivity features such as Projects, memory across conversations and Artifacts. Artifacts can turn a request into standalone content, a visualization, a tool or a small shareable application. Claude can also connect to services such as Slack and Google Workspace, and use connectors compatible with the Model Context Protocol (MCP).

Paid plans extend the ecosystem with specialized products such as Claude Code for software development, Claude Cowork for delegating work tasks, Claude Design and Claude Science. Some of these experiences also have separate ListoolAI profiles to describe their specific use cases.

Claude uses a freemium model. The Free plan supports conversations, web search, content creation and several core capabilities, subject to usage limits. Pro, Max, Team and Enterprise plans increase limits and provide access to more models and features. Anthropic API usage through Claude Console is billed separately.
