Native macOS IDE built in Swift that transpiles source code into anonymized JCross IR before any cloud LLM call, keeping raw code local.
Key Takeaways
Gatekeeper Mode converts Swift or TypeScript into a synthetic intermediate representation (JCross IR), sends it to Claude or GPT, then reverse-transpiles the returned patch back into working code.
JCross Tri-Layer Memory replaces RAG: Kanji topology tokens ([和:1.0], [疑:1.0]) act as semantic anchors that force language modes on small local models (~2B params) without context pollution.
Apple MLX backend enables ultra-low latency local inference on Apple Silicon; BitNet 1.58-bit models run silently in the background as L1 taggers without consuming main GPU budget.
Windows port requires a full Swift-to-Rust core rewrite plus swapping MLX for llama.cpp; solo builder is holding that until macOS version reaches feature completion.
Built with Swift and SwiftUI, requires macOS 14+ and Xcode 15+; distributed as an open-source repo with Xcode project build.

Notable Comments
@kofdai: Builder is a student; core thesis is that frontier model reasoning power and proprietary code confidentiality are mutually exclusive without a blind-proxy layer like Gatekeeper.
