Anthropic’s documentation is spread across five domains. This page collects them in one place so you don’t have to hunt.

Primary domains

Domain	What’s there	Best for
claude.ai	Chat interface, conversations, Projects	Using Claude day-to-day
claude.com	Product/marketing pages, pricing, download, plugin and connector directories	Account management, downloads, browsing plugins
support.claude.com	Help articles, troubleshooting, feature guides, custom skills documentation	How-to questions, troubleshooting
docs.anthropic.com	API documentation, model specifications, developer guides	Building on Claude, API integration
code.claude.com	Claude Code documentation: installation, configuration, usage	Claude Code CLI setup and usage
modelcontextprotocol.io	MCP specification, server implementations, protocol documentation	Building connectors, understanding MCP

Domain changes

Product and marketing pages (pricing, downloads, plugin directory) are now at claude.com. The chat interface remains at claude.ai. Both domains work, but claude.com is the canonical home for non-chat pages. API documentation at docs.anthropic.com is migrating to platform.claude.com/docs. Old URLs still work, but you may see redirects over time.
