Helmwise is an AI-powered passage planning platform built for sailors who take safety seriously. We combine real-time data from multiple sources with specialized AI agents to deliver comprehensive passage plans in seconds.
To make comprehensive passage planning accessible to every sailor, reducing risk through better information and analysis.
Every feature we build prioritizes mariner safety. We apply conservative margins, present worst-case scenarios, and never suppress warnings.
We show our data sources, explain our recommendations, and make it clear when data is uncertain or stale. You always know why we recommend what we do.
Helmwise uses the Model Context Protocol to coordinate specialized AI agents. Each agent is an expert in its domain, working in parallel to deliver comprehensive analysis in seconds.

Helmwise is designed as a supplementary tool to assist with passage planning. It is not a replacement for proper seamanship, navigation skills, or professional judgment. All data and recommendations should be verified against official sources.
