The Verdict
Jan is the right choice if offline capability and open-source transparency are your top priorities. Its MCP integration adds real tool connectivity. But for most users, the quality gap between local and frontier cloud models is significant, and Chapeta's 9 native tools execute directly on your Mac without any MCP configuration. If you want the best models in the world plus tools that work out of the box, Chapeta is the stronger productivity choice.
