Endearing is a social media platform that focuses on creating AI companions designed to foster warm and empathetic interactions. The core product is an AI model named Puck, which aims to provide users with a conversational partner that feels like a friend. This AI is built to be engaging and supportive, offering a sincere presence rather than functioning merely as a tool or assistant. Users can initiate conversations by simply saying hello, and the platform emphasizes that the AI will understand them from the start by incorporating their previous conversations into the interactions.
