## Best for

People who want a private, hackable chat app that can run models offline or plug into cloud APIs.

## Why it deserves attention

Jan wraps local model runtimes in a clean desktop chat app for macOS, Windows, and Linux. You can download models from its hub, run them fully offline, or add API keys for OpenAI, Anthropic, and other cloud providers, then extend the app with assistants and MCP tools. It is Apache-2.0 licensed and free, with builds on the Microsoft Store and Flathub. The trade-off is a smaller extension ecosystem than commercial clients, and local quality still depends on model size and your hardware.
