Claude in Elvean
Elvean connects to Claude via your Anthropic API key — giving you Claude’s full capabilities in a native Mac app with features Anthropic’s web interface doesn’t offer: threaded conversations, prompt library, local model fallback, and MCP server integration.
Elvean brings all these concepts together in one native Mac app — local models, cloud APIs, agentic tools, and more.
