Elvean

Elvean is a native Mac desktop app that acts as a unified AI workspace. Instead of juggling tabs for ChatGPT, Claude, Gemini, and local models, you get one interface where you can switch providers mid-conversation using @mentions. Bring your own API keys — data goes directly to the provider, and keys are stored in macOS Keychain. No account is required to start.

The app goes beyond simple chat. Responses aren't just text — they can include interactive Chart.js charts, sortable and filterable tables, embedded Apple Maps with pinned locations, photo galleries, and Mermaid diagrams. You can fork any message to explore a different direction without losing context, and branch into threaded side conversations. Projects support persistent system instructions, a knowledge base that models can read and write, and an auto-distill feature that extracts key facts after each response. For developers, each project can spin up an isolated Linux container with a terminal that the AI controls — install packages, write files, and run commands directly.

Elvean is built for people who work across multiple AI models and want full control over data and privacy. It's especially useful for developers, researchers, and knowledge workers who need structured outputs, code execution, and deep integration with existing tools like Slack, Notion, Linear, and Sentry through MCP connectors. The free tier gives you unlimited conversations and access to all models (with your own keys), while the Pro plan at $4.99/month adds projects, knowledge base, agentic tools, interactive content, and more.
