TSUKUYORO, a web service that enables businesses to use apps created with generative AI, is scheduled to launch in late October 2026. Users load the service's dedicated file into the generative AI they normally use, then test the app and publish it as a business application.
TSUKUYORO provides integrated support from app testing through maintenance and operation. Standard features include operation from domestic data centers, encrypted communications, measures against unauthorized access and regular backups. Depending on the plan, engineers also provide support with investigating issues and guidance on fixes.
The service offers 250 sample apps for a range of business functions, including meeting-room reservations, inventory management, daily reports and internal surveys. Samples by department and industry are also available, and users can operate them in a browser to assess and create apps suited to their own operations.
Plans start at ¥9,800 per month excluding tax, with a free trial for the first month. The 5 plans are Small, Business, Pro, Enterprise and Custom, with various combinations of user numbers and storage capacity.
