SpiralAI announced RyzaChat:AI on August 4, 2026, as a free-scenario AI chat RPG for iOS and Android licensed by Koei Tecmo Games and set in the world of Atelier Ryza. Players advance travel, alchemy, and battles by talking to Ryza rather than selecting commands, and can switch between an RPG Mode for story progression and a Chat Mode for casual interaction. The text AI is SpiralAI's own SpiralLLM, trained on the original game's scenarios and setting materials. The project's stated principles include handcrafted assets supervised by illustrator Toridamono with no image or video generation AI, Ryza's voice taken from recordings made exclusively for the app by original voice actress Yuri Noguchi, and royalties returned to the illustrator, voice actor, and IP holders.
The release did not go as scheduled. SpiralAI set August 18, then postponed it on August 18, citing higher-than-expected pre-registrations and the need to strengthen servers. The app launched August 25, with SpiralAI attributing the delay to securing additional GPU resources for real-time AI processing. It launched in Japan and has since rolled out overseas, supporting Japanese, English, Brazilian Portuguese, Indonesian, Hindi, and Traditional Chinese.
At Tokyo Game Show 2026, during a Koei Tecmo Games stage, SpiralAI announced a second app, SophieChat:AI, set in the world of Atelier Sophie 2, in development with pre-registration opening the same day. Voice actress Yuka Aisaka demonstrated the development demo. The same stage confirmed skin additions for RyzaChat:AI drawn from new Ryza illustrations, starting with a China dress skin and a Halloween skin, both tentative, with more planned for December 2026 and January 2027. SpiralAI CEO Yuichi Sasaki said a four-player multiplayer mode and a Travel Mode using a map of Japan are at the consideration stage.

SpiralAI CEO Yuichi Sasaki said a multiplayer mode for up to four players and a Travel Mode that uses a map of Japan are still at the consideration stage.

SpiralAI announced on September 18 that SophieChat:AI is in development, a free-scenario AI chat-format RPG set in the world of Atelier Sophie 2: The Alchemist of the Mysterious Dream. Players travel, synthesize, and fight by talking. The reveal came during a Koei Tecmo Games stage event at Tokyo Game Show 2026, held at Makuhari Messe from September 17 to September 21. Voice actress Yuka Aisaka, who voiced Sophie, demonstrated the development demo version on the streamed stage. The game follows RyzaChat:AI: The Story of Just One Summer You Create with Ryza, which SpiralAI launched in August 2026 under license from Koei Tecmo Games. That title slipped from its planned August 18 release to August 25 to strengthen servers after pre-registrations exceeded expectations. The same stage confirmed that the Ryza app will add skins drawn from new Ryza illustrations across the series, starting with a cheongsam and a Halloween skin.

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. The Ryza app launched domestically on August 25 and has since rolled out overseas. SophieChat:AI is in development.
Aug 26
SpiralAI launched RyzaChat:AI Ryza to Create Your Own One-Summer Dream Story on August 25, 2026, for iOS and Android in Japan. The free-to-play app, licensed from Koei Tecmo Games, is a free-scenario AI chat RPG set in the world of Atelier Ryza 1 through 3. Players talk to Ryza to travel, gather materials, synthesize, and fight, with no fixed script. The release was originally planned for August 18, but pre-registrations exceeded expectations, so SpiralAI delayed it to secure additional GPU resources for the real-time AI processing. Ryza's voice uses recordings by original voice actor Yuri Noguchi, synthesized with SpiralAI's own technology, and the text model is SpiralLLM, trained on all Ryza scenarios and setting books. Illustrations by Toridamono are hand-made, with no image or video generation AI. The app supports Japanese, English, Brazilian Portuguese, Indonesian, Hindi, and Traditional Chinese, with a global version planned. Revenue is returned as royalties to the illustrator, voice actor, and IP holders.

Aug 6
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.
Aug 4
SpiralAI announced on August 4, 2026 that it will release RyzaChat: AI Ryza and the One Summer Dream Story You Create, a free-scenario AI chat RPG licensed by Koei Tecmo Games. The app is scheduled for release in August 2026 on iOS and Android, and pre-registration opened the same day on the official website. Set in the world of Atelier Ryza: Ever Darkness & the Secret Hideout, the game lets players advance travel, alchemy, and battles through conversation with Ryza rather than command selection. Players can switch between RPG Mode for story progression and Chat Mode for casual time with the character. The text AI uses SpiralAI's proprietary SpiralLLM, trained on all scenarios and setting materials from the original game. The project follows five stated principles: all Ryza assets were handcrafted under illustrator Toridamono's supervision with no image or video generation AI used, Ryza's voice uses recordings made exclusively for the app by original voice actress Yuri Noguchi, the world follows the original map under Koei Tecmo Games supervision, and revenue is returned as royalties to illustrators, voice actors, and original IP holders.
