Building an Android Input Method Editor (IME) is notoriously difficult. You are operating in a highly restricted memory environment, and your service must remain alive and responsive at all times. Any crash means the user cannot type, which is a critical failure.

To accommodate our AI features without bloating the keyboard, we had to adopt a strict modular architecture. The core typing engine and spell-checking mechanisms run entirely offline and process independently of the AI layer. The AI UI components (like the glowing 'Enhance' button) are lazy-loaded only when requested. This ensures that TypePilot feels exactly like a stock, high-performance Android keyboard 99% of the time, seamlessly transforming into an AI powerhouse only when you click the button.
