"AI Persona Town" Where Anyone Can Ask Questions - New Service "Koemachi" Launched. Corporate "PersonaChoice" Evolves to v3.0, Headquarters Relocated

Dotify Inc. (Headquarters: Chiyoda-ku, Tokyo) has launched "Koemachi" (https://koemachi.com/), a new service that allows anyone to ask questions to AI personas in a virtual town. In addition, we announce the release of a major update, v3.0, for the corporate AI persona decision-making simulation "PersonaChoice" (June 8, 2026), and the relocation of our headquarters due to business expansion (Kasumigaseki Building - June 24, 2026).

Koemachi - A Service for "I wonder what that person living next door thinks?"

Koemachi is a fictional town inhabited by 150,000 AI personas (100,000 Japanese, 50,000 foreign nationals) who are "statistically likely to exist," generated from statistical data such as national censuses. Each persona answers questions as an "individual" with their own age, occupation, residence, income, and personality, so the responses are not just aggregated values but "voices" with the texture of real life.

At launch, the following two features are available:

Serialized Series "I Asked the Residents of AI Town" (3 installments per week, 3 installments already published at launch) Each installment poses a question to the town, aggregates the responses of hundreds of residents by attribute, and delivers them as reading material along with comments explaining the reasons. Each article can be viewed on the official website (https://koemachi.com/) and is also distributed on X (@koemachi) and in short videos.

Call for "Topics to Ask About" We accept "What would happen if we asked AI personas about this?" topics through a form on the official website. Adopted topics will be featured in the serialized series. We welcome any topic, whether it's something difficult to ask in reality or something whose results might change depending on who answers.

Example from the Series: In the first installment, "What will you use your summer bonus for?", the top answer among 500 working residents was "Savings" at 46%. However, for those with an annual income exceeding 10 million yen, "Investments" at 47% surpassed savings. For bonus day luxuries, men tended to "treat family or partners," while women preferred "massage/sauna," showing a clear division. In the second installment, "Would you take a job interview if it were an 'AI interview'?", 74.6% said "Yes," but the majority of those were "Reluctant but would do it" (59.6%). Furthermore, only 20% answered "AI is fairer," with a generational reversal: 54% of those under 20 said "AI is fairer," while only 17% of those over 60 agreed. The divergence of opinions based on attributes and the human-like reason comments from residents are the highlights of Koemachi.

Background of Development - Fostering a Culture of "Ask First Before Conducting Formal Research" for Everyone

PersonaChoice, the corporate service operated by Dotify, has seen increasing use in fields like marketing, product planning, and recruitment for "asking AI personas before conducting formal research" and "using them as a sounding board for ideas." In conversations with client companies, a common request was, "Even outside of work, there are questions I genuinely want to ask." To address these "things I want to ask someone," such as societal concerns, seasonal topics, and simple everyday curiosities, we created a platform where anyone can submit questions to the AI persona town without a corporate contract. That is Koemachi.

PersonaChoice v3.0 - Significantly Improved Response Realism and Accuracy (Available from June 8, 2026)

PersonaChoice, which also serves as the foundation for Koemachi, received a major update to v3.0 in June.

Improved Response Realism: Replicates "opinion dispersion" and "minority opinions" found in actual surveys, achieving a more natural response distribution.

Improved Response Accuracy: Further enhanced consistency with the results of various real-world surveys.

Enhanced Stability for Large-Scale Execution: Strengthened the processing infrastructure for simultaneous simulations by numerous AI personas.

Existing customers can use v3.0 without any procedures, setting changes, or additional fees. Its applications are steadily expanding in various fields, including marketing, product planning, and human resources.

Additionally, due to business expansion, we are seeking sales agency partners who can help deliver PersonaChoice to our customers. We welcome collaborations with companies engaged in supporting corporate decision-making, such as those in research, marketing, human resources, and advertising. Interested parties are encouraged to inquire through the official PersonaChoice website.

Due to business expansion, our headquarters have been relocated as of June 24, 2026.

New Address: 36F, Kasumigaseki Building, 3-2-5 Kasumigaseki, Chiyoda-ku, Tokyo 100-6036

Future Developments

Koemachi plans to sequentially expand its town experience, including enhancing the system for soliciting and adopting "topics to ask about" from readers. PersonaChoice will continue to evolve as a platform supporting the culture of "asking first before conducting formal research," such as by building synthetic audiences for corporations.
