What is Quark?
The title of the homepage of Quark's official website is "Quark_ Official Website of AI Flagship Applications". The navigation divides the product line into sections: Quark Cloud Disk, Global AI Assistant, Quark PDF, Quark Scanner, Search API, and User Guide. The logic on the browser side is to place AI at the system level: the official website describes the OS-level AI assistant as "Sidebar, floating ball, screen sharing, can be invoked anytime globally, making cross-application task processing more efficient". Above this are four conventional but high-frequency browsing capabilities: reading mode, web page erasure, web page translation, and tab management. Extending down to the cloud disk and scanner, the official website emphasizes that it fully opens up the two major capability domains of Quark Cloud Disk and Quark Scanner to support AI Agent calls, enabling conversations in the browser to directly access files and OCR. The overall proposition of the official website is "There is no need to open other apps; one browser can run the entire workflow".
Who is it for?
- Office workers who need to complete information searching, long article reading, translation, PDF processing and PPT creation in a single browser.
- Students and those taking postgraduate entrance exams or civil service exams use the Scanner King for OCR, converting photos to documents, and removing handwritten marks from exam papers.
- Heavy users of cloud storage who want to directly find files in the cloud storage by describing their features in natural language.
- Video learners who watch long foreign-language videos with automatic subtitles and translation.
