SophieChat:AI, a free-scenario AI chat-format RPG set in the world of Atelier Sophie 2: The Alchemist of the Mysterious Dream, is in development. SpiralAI announced the project on September 18 during a Koei Tecmo Games stage event at Tokyo Game Show 2026.
SpiralAI and Koei Tecmo Games announced SophieChat:AI on September 18, an AI chat app set in the world of Atelier Sophie. A companion announcement the same day placed it specifically in the world of Atelier Sophie 2: The Alchemist of the Mysterious Dream and described the format: players travel, synthesize, and fight by talking. The title is free-scenario and in development. 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 project follows RyzaChat:AI: The Story of Just One Summer You Create with Ryza, the free-scenario chat RPG for iOS and Android that SpiralAI developed under license from Koei Tecmo. That app launched domestically on August 25, slipping from a planned August 18 release to strengthen servers after pre-registrations exceeded expectations, and has since rolled out overseas. The same stage event confirmed that RyzaChat:AI will add skins drawn from new Ryza illustrations across the series, starting with a cheongsam and a Halloween skin.
SpiralAI is using the Ryza app's numbers to justify extending the format to a second Atelier heroine before the first app is a year old. The stage figures cited 15 million total utterances, over 100 million X impressions, and a top spot in the App Store free entertainment ranking for RyzaChat:AI. SophieChat:AI has no release date, platform list, or pricing beyond the free-scenario description.
