What It Is

幹事職人 is a Japanese event-organizer assistant with a very clear focus: using AI to help decide the date and venue for drinking parties, group dinners, and similar gatherings. Users simply create a URL and share it in a group chat; participants then enter their availability, budget, preferred area, desired restaurant atmosphere, and other preferences. Once the deadline arrives, the AI makes the decision automatically. It is not trying to solve complex project scheduling, but rather the communication pressure common in Japanese social settings: who has to be the organizer, and who has to make the final call.

Core Features and Experience

Based on the available text, AI is mainly used to propose or automatically decide the schedule and venue, but the service does not disclose its specific model, algorithm, or data sources. A key highlight is the ability to “tell the AI the truth” privately: for example, information such as not wanting to attend or being unable to eat fried foods is not shown to other participants, which helps reduce awkwardness in group chats. No registration is required, and a single URL is enough to collect responses, making it well suited for sharing via LINE and other messaging tools.

Pricing and Data Privacy

The service is clearly labeled as completely free and requiring no registration, and its terms also state that it is provided free of charge. No paid plans or usage limits are visible. For data handling, event data is automatically deleted 30 days after creation, and the creator can also delete it manually via the deletion URL. Once deleted, it cannot be restored. This is a practical, lightweight data lifecycle design. However, the terms also state that user-submitted content may be used by the service provider free of charge, and there is no fuller privacy policy, encryption information, or explanation of whether third-party AI processing is involved.

Pros, Cons, and Limitations

Its strengths are its extremely low barrier to entry, focused use case, and ability to shift final decision-making responsibility to AI, reducing interpersonal friction. The drawbacks are also clear: AI output is only for reference, and the service provider does not guarantee completeness, accuracy, or usefulness. There are also no visible integrations with APIs, calendars, maps, or restaurant booking platforms. For serious business meetings, large events, or scenarios requiring audit records, its reliability and controllability are not sufficient.

Who It’s For and Access from China

It is best suited for lightweight scenarios such as friend gatherings, small-team drinking parties, and community events, especially for people who do not want to take on the organizer role. For users in China, the site does not provide information about access, payment, or Chinese-language support, so its accessibility can only be considered unknown. Alternatives include scheduling tools, survey forms, LINE/group polls, or domestic options such as Feishu, WeCom, and Tencent Questionnaire.
