## In brief
Xiaoke Rexian is the “小科热线” AI science assistant from 科技日报社 / Science and Technology Daily. The own launch report describes generative questions and answers grounded in its editorial science corpus, with reports as supporting sources. It serves science-interested readers of the news client. Answers draw on that source collection; the provider’s claimed elimination of hallucinations is not independently confirmed here.


## Limits
Install the official news client and open the “小科热线” floating window on its home screen. Registration is specified for the documented free use. General app privacy rules describe phone/SMS sign-in and phone binding with third-party login. Minors need the documented guardian consent and guidance. Check answers against cited reporting. The general app privacy policy is not a separate current model agreement.
