Anthropic's AI assistant for long documents, writing, analysis and code.
Claude is a conversational AI assistant built by Anthropic. People use it to draft and edit text, summarize reports, analyze uploaded documents and write or review code. Projects let you group related chats and reference files, which helps when a task spans many sessions. The web app, desktop app and mobile apps offer the same core chat experience. Claude suits writers, analysts and developers who work with large amounts of text and want careful, structured responses. Like any language model it can make mistakes, so verify facts, figures and quotations before using them. Limits on messages depend on the plan, and some advanced features are reserved for paid tiers.
Free tier available; paid plans unlock higher limits. Check the pricing page for current prices.
