## In brief
Yunguo Zhiyi / 云果知一 by 深圳市百麒晟科技有限公司 is an AI service for compatible smartwatch apps. Its own product announcement explicitly maps the original model to adult work assistants and child homework apps. Adults can discuss work plans and ideas or search personal notes semantically. Basic homework and knowledge questions are described for children aged seven and above under continuous guardian supervision. The service combines technologies including Doubao and DeepSeek with local AI capabilities, rather than offering a separate foundation-model download here.


## Limits
The documented acquisition route is a product or integration request through the vendor support form. The product page explicitly directs documentation, cooperation and interface enquiries there. Name, email, title and description are required; WeChat and phone are optional. End users need an actually supported device and the enabled app. A download for any watch or public webchat is undocumented.
