KAI is a personal AI that doesn't wait for you to open an app — it calls your phone like a real incoming call, remembers everything you've ever told it, and quietly runs your day. Ask it to remind you about something and it doesn't just ping you, it rings you and follows up until it's done. v9 adds hands-free Live Talk voice, Google Calendar sync, instant chat streaming, and a home-screen widget. Free on Android.
