> How LazyJack thinks, how to use it through a season, and how to work with it through an AI assistant.

LazyJack is a record for one sailboat, kept by its owner, that works offline and opens to an AI assistant over MCP (Model Context Protocol) at https://app.lazyjack.app/api/v1/mcp. The guide below uses the app's own words; the chapter "How LazyJack thinks" maps them to the names the data and the MCP tools use.
