Claude

Claude is an AI assistant developed by Anthropic, a research company focused on building reliable and steerable AI systems. It handles natural-language conversations and is well suited to long-form writing, summarizing dense documents, analyzing data, and reading or generating code. Claude can process large amounts of text at once, work with uploaded files and images, and follow detailed, multi-step instructions with careful reasoning.

The assistant appeals to professionals, developers, and teams who value well-structured output and a lower rate of fabricated answers. Anthropic trains Claude using a method it calls Constitutional AI, which aims to keep responses helpful while avoiding harmful or misleading content. Features such as Projects, artifacts, and connected tools help users organize ongoing work.

Claude is available through a free tier and paid Pro, Max, Team, and Enterprise plans, plus a developer API. It can be used on the web, desktop, and mobile, as well as through major cloud platforms.
