The semantic tool registry for AI agents. One local broker between any agent — Claude Code, Codex, Cursor — and all your MCP servers, handing it only the right tools per task, in any language. Seven built-in modules — call tracing, policy gates, output condensing, web retrieval, semantic cache, memory, and source grounding — plus a live receipt that shows exactly what it saved on your setup.
Navi and Boat, one chart. Navi: how much water is under your keel, now and for the next 48 hours, coloured on the chart for your boat across San Francisco Bay and the Delta — offline, from NOAA's own charts. Boat: connect the boat's Wi‑Fi and the chart runs on its GPS and sounder, the Boat screen shows batteries, tanks, engine and autopilot, and an anchor watch wakes you through the silent switch when the boat drags.

Private, encrypted, offline. An invite-only messenger for the people you actually know: create a chat, share a link or a QR code, and talk. Every message is end-to-end encrypted with keys generated on your devices, relayed through iCloud, or sent directly between nearby devices over Wi‑Fi when there is no internet. No account, no phone number, no server of ours. Smart replies, summaries and translation run on the device.

Understand them, then know what to say. Hear a conversation in your own language, in your own headphones, as it is spoken. When they finish, three short replies appear in their language with the meaning in yours: tap one and your iPhone says it, or hold to talk and it translates you. Speech, translation and suggestions run on the iPhone; nothing saved unless you choose.
