# Nausika · real maritime data for your AI assistant — sailing, routing, forecasts

> Nausika provides authoritative, real-time maritime data such as sea-aware routing, marine forecasts, tides, and curated sailing places in the Mediterranean to ground AI assistants with verifiable, citable information.

Nausika is a connector designed to integrate real maritime and nautical data into AI assistants, ensuring that responses related to sailing, routing, weather, tides, and port information are accurate, timely, and sourced from reliable datasets. During its public beta, coverage is restricted to the Mediterranean Sea, enhancing the safety and precision of maritime planning and assistance.
