Short answer: K-AI: A personal AI agent whose memory lives on your Mac: Kai watches the mail, chat and calendar you choose, runs errands such as reorders, bookings and forms on its own virtual computer inside your Mac, and waits for your OK on payments, deletions and account changes. Nico (NativeMind): A voice-to-action personal agent that lives on your Mac: hold right ⌘, speak, and a sandboxed on-device Worker gets things done with your files, Mail, apps and browser logins — not on a cloud computer.
