Partial The macOS app shell and UI are vibe-codeable, but reliable computer-use with an on-screen cursor, a local model that indexes the user's private sources overnight, and a polished voice-matched reply system are hard to make robust.
What it would actually take: The stack would be a native macOS app (Swift) with local indexing of mail, messages, notes, and calendar via system APIs, an on-device or local LLM for summarization and style modeling, and a computer-use agent that drives the UI with accessibility APIs and screenshots. The hard parts are reliable GUI automation across apps, efficient on-device inference, and handling OS permissions and privacy. This needs experienced systems and ML engineers.
