1. Service description

1. The Service

We provide users with multimodal interactive artificial intelligence services. This Service is primarily intended for adults aged 18 and above. If you are under 18 years old, please read and fully understand this Agreement carefully and obtain the consent of your legal guardian before you can use the Service.

2. Risk reminder

If you use the Service to deal with matters that may have a significant impact (including but not limited to medical health, financial investment, insurance business, legal affairs, food safety, etc.), it is recommended that you consult professionals in the corresponding fields. All output content from the Service is for reference only and should not be used as the sole basis for your subsequent decision-making.

The fields of artificial intelligence and machine learning are developing rapidly, and we continue to work hard to improve and perfect our products and services to enhance their accuracy, reliability, security and practicality. However, due to the limitations of existing technical characteristics and capabilities, machine learning is uncertain and probabilistic. The output content of the website and software may contain inaccuracies, lack timeliness, or fail to fully cover the content you need. You should not use it as the only basis for making decisions, and you should verify the content in key scenarios. We make no representations or warranties of any kind regarding the accuracy, completeness and functionality of this web page or software-generated content. All consequences and responsibilities arising from any judgments and subsequent actions you make based on the output content of the website and software are your own responsibility. Please understand generative artificial intelligence technology scientifically and rationally and use it in accordance with the applicable laws.

The output content of the Service does not represent our position or opinion. If the content mentions third-party products or services, it does not mean that the third party endorses the content or is associated with the website or software. We provide no endorsement, undertaking or warranty for its authenticity, accuracy, and reliability.
