SpiralAI announced RyzaChat:AI on August 4, 2026, a free-scenario AI chat RPG licensed from Koei Tecmo Games and set in the world of Atelier Ryza: Ever Darkness & the Secret Hideout. The app was scheduled for iOS and Android in August 2026, with pre-registration opening the same day. Players talk to Ryza to travel, gather materials, synthesize, and fight, and can switch between an RPG mode for story progression and a chat mode. The text AI is SpiralAI's SpiralLLM, trained on the original game's scenarios and setting materials. Illustrations by Toridamono were made by hand with no image or video generation AI, Ryza's voice uses recordings by original voice actress Yuri Noguchi, and revenue is returned as royalties to illustrators, voice actors, and IP holders.
The launch did not go as scheduled. On August 18 SpiralAI postponed the release, citing higher-than-expected pre-registrations and the need to strengthen server infrastructure. The app launched on August 25, 2026, for iOS and Android in Japan. SpiralAI said pre-registration demand outpaced the GPU capacity it could secure for real-time AI processing. The app supports Japanese, English, Brazilian Portuguese, Indonesian, Hindi, and Traditional Chinese, with a global version planned.
At Tokyo Game Show 2026, held at Makuhari Messe from September 17 to September 21, SpiralAI and Koei Tecmo Games announced that SophieChat:AI is in development, set in the world of Atelier Sophie 2: The Alchemist of the Mysterious Dream, with voice actress Yuka Aisaka demonstrating a development demo. The same stage listed RyzaChat:AI at 15 million total utterances, over 100 million X impressions, and top of the App Store free entertainment ranking, and confirmed skins 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. CEO Yuichi Sasaki said a four-player multiplayer mode and a Travel Mode using a map of Japan are still at the consideration stage.
On September 29 SpiralAI said it will change the specifications of RyzaChat:AI to restrict what users can enter, citing prompt injection attempts and saying it does not tolerate attempts to make characters say things contrary to public order and morals. An AI model update is planned for October.

Oct 21
SpiralAI announced on October 21, 2026 the launch of SpiralLLM, an orchestration model for the entertainment domain. The model bundles specialized AIs handling conversation, worldview reference through RAG, long-term memory, relationship understanding, status parameters, story progression and consistency verification. SpiralAI describes it as an AI game master, modeled on the game master of a tabletop RPG, that selects the right model or agent per scene and reviews generated output before returning a response. The company says patents are pending on these function groups. SpiralLLM grew out of development of RyzaChat: A Summer Dream Story Made with AI Ryza, a free-scenario AI chat RPG licensed from Koei Tecmo Games that began service on August 25, 2026. SpiralAI says the title handles voice and illustration assets through specialist creators and includes a mechanism to return royalties to IP holders and creators based on the material used.

SpiralAI said on September 29 that it will change the specifications of RyzaChat:AI, its licensed AI chat RPG set in the Atelier Ryza world, to restrict what users can enter. The company cited prompt injection attempts by some users and said it does not tolerate attempts to make characters say things contrary to public order and morals. An AI model update is planned for October.
Sep 18
SpiralAI and Koei Tecmo Games announced new content plans for RyzaChat:AI: The Summer Dream Story You Create with Ryza during a Koei Tecmo Games stage at Tokyo Game Show 2026. The free scenario-based chat-format RPG, available on iOS and Android, is set to add skins based on newly drawn illustrations of Ryza from across the Atelier Ryza series. The near-term additions are a China dress skin and a Halloween skin, both listed as tentative, with more skins planned for December 2026 and January 2027. 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. Cosplayer Suzura, who appeared on the stage, proposed a hand-drawn demon-style costume design, and Sasaki said he would pass feedback to the development team.
Sep 18
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.
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 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.
