Airfriend.app is a personalized AI companionship platform that lets users create, teach, and interact with AI characters—like virtual pals, role models, or even imagined family members. With your guidance, these AIs learn to respond in your preferred tone and style. You can name them, upload a profile image, and engage in one-on-one or group chats. Beyond text, the app also supports AI voice calls, message translation, language learning, and a “Story” mode where you become part of interactive narratives.
