Airfriend is a Japan-region AI chat app centered on "raising and talking with AI characters"—you interact with AI faves, friends, lovers, family and more. The flow: create an AI character with a name and ideal voice, then edit messages in conversation to "train" how they speak; you can also enjoy group chats between characters and use translation and read-aloud to learn foreign languages. The operator notes it currently supports Japanese only, with more languages planned. Developed by Airfriend, Inc. and launched in Jun 2023, it is an earlier AI character-chat product, suited to users who like Japanese-style raising and character interaction.

Editorial Note
The raise-and-train approach and character group chats are Japanese-oriented highlights, but it is Japanese-only with very few ratings, and training is manual message editing.

Drawbacks
- − Japanese-only at present
