Could you build this?
Partial While wrapping a local runtime like Ollama or llama.cpp in an Electron/Swift desktop app is achievable, training or optimizing custom 4B/27B models to run reliably at high token speeds across varying local hardware requires model engineering.
What it would actually take: The architecture would combine a native macOS app (Swift/SwiftUI) with a local inference engine utilizing Apple Silicon Metal/CoreML (via llama.cpp or MLX). The hard parts are fine-tuning a small model (4B/27B) to reliably handle complex tool calling (email, calendar, local apps) with low latency, and managing local OS permissions, background execution, and audio capture without heavy resource drain.
