A personal AI assistant is not a luxury tool. It is a productivity asset. It saves time. It increases focus. It improves learning speed. It automates repetitive work. The future belongs to people who build systems, not just use apps. Your assistant does not need to be perfect. It only needs to be useful. Start small. Grow it over time.
