Loci
A dual-register second brain for iPhone & Vision Pro

Loci is a private, on-device "second brain" for iPhone and Apple Vision Pro that holds your life in two registers at once: the empirical — what your own data actually says — and the imaginal — the recurring image, the archetype, the memory bound to a place. Built natively on Apple's 2026 stack: the Foundation Models framework, App Intents, and visionOS spatial anchors.
Problem: Note apps flatten everything into searchable lists that only capture the literal. But a life isn't only facts — it's also the images, patterns, and meanings that recur, and the memories tied to the places you move through. Tools that see only one register miss half of what matters.
Solution: An app that runs both registers side by side — the empirical read of your own data and the imaginal read of your symbols and places — with intelligence on-device via Apple's Foundation Models framework and thoughts anchored to real space through visionOS. Everything stays private on the device.
