AI Web Application Development

I require an Ai web app where users login and have an avatar that looks like them based on either facial scan or from an image. The Ai avatar talks to the user, gets to know them more and more and can answer questions about all aspects of life based on knowing them over time. It will be like chatgpt with an avatar that looks like you and personalised. It will be personal conversations with recommendations. Metamask / web3 login will be incorporated. Details will be provided to the winning bidder
