PAI, the world’s first Personal AI (PAI), a 3D intelligent avatar designed to look like you, speak like you, and behave like you in the digital space. A person’s PAI is directly owned and managed by the original user, who can be compensated for deploying their PAI online, creating a new AI economy. The unique, AI blockchain protocol enables the decentralization of PAI and contains many layers: authentication, network, storage, and AI. The PAI Network is a decentralized platform built from the protocol, and acts as an avatar repository and foundation for decentralized applications to use PAI in everyday life. As the AI economy grows, the blockchain protocol will be able to be used for purposes beyond PAI and other general broad-domain AI development.
