QQ Browser has introduced an intelligent tool called the "PDF Reading Assistant," which users can apply to join for experience testing. This tool is powered by Tencent's Hunyuan large model and can be used anytime on mobile phones or computers. It features intelligent summarization, smart Q&A, and original text location, helping users quickly obtain the information they need and better understand the content of documents. In the future, the tool will be expanded to more applications, providing more comprehensive support.
