Two Atelier AI chat apps are in motion: the two most recent stories report RyzaChat:AI is available on iOS and Android, with one noting overseas rollout after its August 25 domestic launch, and Koei Tecmo announced a second app, SophieChat:AI, is in development. The older August 6 story announced an August 18 release for RyzaChat:AI, which the newer story does not repeat.
Atelier Ryza is currently the basis for an AI chat app, RyzaChat:AI, built by SpiralAI under license from Koei Tecmo Games. The August 6 announcement set an August 18 release for iOS and Android and described the format: a free-scenario industry RPG in which conversation with Ryza advances travel, alchemy, and battles. Two modes are offered, RPG Mode for story progression and Chat Mode for leisurely interaction. The AI runs on SpiralLLM, trained on scenarios and setting materials from the original Atelier Ryza, and conversation content is not used to train the model.
Assets are handcrafted under the supervision of illustrator Toridamono, with no image or video generation AI used. Ryza's voice uses recordings by original voice actress Yuri Noguchi, recorded for the app and operated through SpiralAI's proprietary voice synthesis. Revenue is returned as royalties to the illustrator, voice actress, and original IP holders. Pre-registration opened alongside a user survey that closed on August 17, asking seven questions about feelings toward free-scenario AI chat RPGs, future project candidates, and questions for an August 18 live stream.
The September 18 story reports RyzaChat:AI launched domestically on August 25 and has since rolled out overseas. The same story announced SophieChat:AI for the world of Atelier Sophie, in development, following the Ryza app's licensing model.
The two stories disagree on the domestic launch date, with August 18 stated in the earlier announcement and August 25 reported after release. Both are recorded here as the stories state them.

Koei Tecmo Games and SpiralAI announced SophieChat:AI on September 18, an AI chat app set in the world of Atelier Sophie. It follows RyzaChat:AI, the free-scenario chat RPG for iOS and Android built around Atelier Ryza, which SpiralAI developed under license from Koei Tecmo.

SpiralAI announced on August 6 that its chat AI app RyzaChat:AI, based on the Atelier Ryza series and licensed from Koei Tecmo Games, will launch for iOS and Android on August 18. The game is a free-scenario AI chat-style RPG where conversing with Ryza advances travel, alchemy, and battles. It offers two modes: RPG Mode for story progression and Chat Mode for leisurely interaction. The AI uses SpiralLLM, trained on all scenarios and setting materials from the original Atelier Ryza, and conversation content is not used to train the model. All assets are handcrafted under the supervision of illustrator Toridamono, with no image or video generation AI used. Ryza's voice uses recordings by original voice actress Yuri Noguchi, recorded exclusively for the app and operated via SpiralAI's proprietary voice synthesis. Revenue is returned as royalties to the illustrator, voice actress, and original IP holders. Alongside pre-registration, SpiralAI began a user survey with a deadline of August 17, asking seven questions about honest feelings toward free-scenario AI chat RPGs, future project candidates, and questions for an August 18 release live stream.
