It works when nothing else does.

With sound.

Sovereign AI

Where the signal ends, it keeps going.

Speech recognition, the language model and the voice can all run on the NVIDIA Jetson inside the box. When you are connected, it can use OpenAI, Anthropic or Gemini with your own key. Navigation data and safety protocols always stay on board.

Monthly fee: €0. The core copilot has nothing to subscribe to.
Your data: Personal data encrypted at rest on the box.
Languages: English, Español and Português, built in.

Knowledge

Your manuals, one question away.

Every fact CaptainLink knows lives in a cartridge you can open: seamanship, regional maritime law, even packs for one boat model. Bring the boat's documents aboard and ask by voice.

CaptainLink knowledge search for man overboard with five matches across four cartridges — Knowledge search, captured from the running app.

Knowledge search, captured from the running app.

Provenance: Each fact is tagged regulatory, best practice or heuristic, and the tag comes with the answer.
Your boat: Dedicated packs for the Beneteau Oceanis and Jeanneau Sun Odyssey ranges.
Your waters: Switch packs on or off. Core safety knowledge always stays on.
Integrity: Each cartridge is checked with SHA-256 before it loads.

Safety protocol engine

For the moment everything changes.

Man overboard: Bearing and range to the position, with an audio broadcast.
Anchor watch: Set a radius. If the anchor drags, the alarm sounds.
AIS threat board: Safe, warning, critical. Alarm when a vessel will pass closer than 0.5 nm within 15 minutes.
MAYDAY: Builds a VHF DSC-format call from the nature of distress and souls on board.

Camera lookoutOn board

The camera spots boats, people and marine life and tells you where, relative to the bow. The box has 8 camera inputs.

The black box principle

The record survives, even when the boat doesn't.

Flight recorders are built so the record outlives the aircraft. CaptainLink applies the same idea: a hardened shell around the box, and one tap to send the whole record somewhere you control.

Shell: 3D-printed, impact- and heat-resistant, designed to protect the record through fire or submersion. A damaged shell reprints in hours. Certification in progress.
Sync Now: Safety events, logbook, voyages and compliance documents leave the boat encrypted, over SFTP.
Destination: A NAS at home, your own server or a private cloud instance. Never a vendor cloud.
Control: Nothing streams automatically. You decide when.
