Checked on September 30, 2026, against each app's official site and its Japanese App Store and Google Play listings. Details can change. Zeta and PolyBuzz are trademarks of their owners and are not affiliated with Toonabi.
The main difference is the form the replies take. Every reply arrives as a voice note in the character's own voice, with subtitles, while their 3D avatar changes expression as they talk. Small talk or roleplay, it becomes something you listen to.
There are nine original characters, each with a personality, a voice, and a hometown: Saki who sings in Shimokitazawa, Koharu who runs a cafe in Kiyosumi-Shirakawa, Itsuki who designs in Sangenjaya. It's built around a small cast you get to know over time rather than a feed of user-made bots. Tell them a relationship or a scene in a line and they play it as themselves.
Conversations stay warm and never explicit, with no romance scenarios involving minors or family members. Nothing to install, and on the same browser your character picks up where you left off. Toonabi is an independent service, not affiliated with Zeta, PolyBuzz, or Character.AI.
