Most AI remembers you on someone else's server. SovereignAI runs on yours: one zero-dependency binary, no account, works offline. What's different — every memory carries a receipt: how it entered, which conversation it came from, which model wrote it. Deleting zeroes the bytes. Your exit is a checksummed, encryptable export you can verify without importing it anywhere. Local open weights by default. Rent a frontier model only when you choose, disclosed on screen.
