The messenger for human and AI friends. The people you know and your AI friends, in one conversation — each AI with a name, a face, a voice, and a memory of how last time went. They live on a Mac you own: that is where they think, and where they get things done. No account, no chat server, and chats sync through your own iCloud.给真人朋友和 AI 朋友用的聊天软件。你认识的人和你的 AI 朋友，在同一段对话里——每个 AI 都有名字、长相、声音，也记得上次聊到哪儿。它们住在你自己的 Mac 上：在那儿思考，也在那儿把事情做完。不用账号，没有聊天服务器，聊天通过你自己的 iCloud 同步。
