Elvean

The product is a private AI workspace for macOS that centralizes chat with multiple AI models, organizes work into projects with a filesystem-based knowledge base, and runs agentic multi-step tasks with interactive charts, tables, maps and a sandboxed Linux environment. It is for developers, data-focused users and individual consumers as well as business users who work on Mac. It is positioned as a native Mac app that connects to local and hosted models via bring-your-own keys and MCP connectors instead of separate browser tabs.
