AI for Boating

Coming soon.

Lir AI is calm, captain-grade navigation intelligence — tides, currents, bridges, locks, and conditions, pulled live from official federal sources and grounded in your vessel's actual numbers. We're still tuning it for the wheelhouse. Join the waitlist and we'll let you know the moment it's ready for real underway use.

The problem

The water doesn't wait.
Neither should you.

Every captain has felt it — standing at the helm trying to piece together tide windows, bridge schedules, lock status, and weather from half a dozen sources while the current is already running against you.

Lir was built to remove that friction. One question. One clear answer. Backed by the same official data the professionals use.

AI — Core, Not a Feature

Ask it anything.
It actually looks it up.

Lir isn't a chart viewer with an AI chatbot bolted on. The AI is the engine. Every briefing, every clearance check, every LNM scan — Lir runs live data tool calls against federal sources and gives you a calm, captain-ready answer. It knows your vessel. It knows your route. It knows what's in your stretch of water.

Example — Ask Lir while underway
Captain
What's the current at Hell Gate right now and is the tide working against us?
Lir
Current at Hell Gate is running ebb at 2.3 kts — against you on a northbound. Next slack is at 14:42 local. If you hold 30 minutes you'll pick up a fair tide for the full run through to Throgs Neck. At your 8 kt cruise speed that saves you about 45 minutes over fighting it now.
Captain
Any LNMs I should know about in the area?
Lir
One active LNM within 15 nm — buoy 14A in the East River channel has been reported out of position. USCG District 1, Week 18. No dredge or cable-lay notices affecting your route.
AI Route Briefing
Full pre-departure package — weather, bridges, tides, LNMs — generated before you leave the dock
Area Briefing
15 nm radial snapshot for when you're anchored or working a local area
Vessel-Aware
Every answer is grounded in your actual boat — LOA, draft, air draft, speed, certifications

Built by a captain

This came from the wheelhouse, not a conference room.

Lir AI was built by someone who has stood watch on the water commercially — not a developer who discovered boating. That matters because the AI knows what actually matters underway: whether the bridge opens on demand or advance notice, whether a 2.3 kt ebb at Hell Gate costs you 45 minutes or gets your anchor fouled, what "delayed" at a lock actually means for your schedule.

The federal data is real. The questions the AI knows to ask are real. The things it surfaces first are what an experienced captain would want to know first.
