Could you build this?
Partial The AI rewriting features are simple LLM API calls, but creating a native, secure, low-latency Android InputMethodService keyboard app has significant platform constraints.
What it would actually take: Building an Android virtual keyboard requires writing native Kotlin/Java code implementing `InputMethodService`, managing keyboard lifecycle, touch layouts, dictionary lookup, and memory footprint carefully. Integrating AI queries requires asynchronous networking without freezing keyboard UI thread, managing on-device keystroke caching, and securely handling authentication and token metering directly within the IME process.
