An AI life agent is a personal assistant that runs on your phone 24/7 via WhatsApp. Not ChatGPT — a custom-built agent that knows your preferences, manages your email, handles your calendar, browses the web, orders food, and even makes phone calls on your behalf. The concept was popularized by developers building "Aurelion-like" agents — named after an open-source project that demonstrated a fully autonomous personal AI. The difference from chatbots: it takes ACTION, not just gives advice.
