Could you build this?
Partial While the translation logic is an API call, implementing a system-level macOS Input Method Engine (IME) requires complex Apple InputMethodKit programming and strict IPC event handling.
What it would actually take: Built with Swift/Objective-C using macOS InputMethodKit and Carbon TSM frameworks to intercept global keystrokes and render customized floating candidate palettes. The hard part is managing real-time low-latency text compositional states across various target apps (sandboxed and non-sandboxed) without dropped inputs, coupled with local bilingual dictionaries or cached bilingual embeddings.
