Detect and reduce AI-generated traces in academic papers across CNKI, VIP and other Chinese platforms
Run checks modelled on CNKI, VIP, Gezida, Daya, Wanfang and an overseas detector to see how AI-generated your text looks before you submit it.
Dedicated rewriting optimises passages so they carry fewer traces of machine generation, with the vendor reporting typical results under 10% on the simulated platforms.
A separate rewriting mode targets similarity against published literature, offering varied phrasings while keeping the original meaning intact.
Document-wide processing that rewrites the whole paper at once rather than forcing you to edit paragraph by paragraph.

The AI productivity suite with agents, email, and docs that work wherever you do
Superhuman Go brings AI agents into the tools and tabs you already use, with inline suggestions and context-aware chat.
Auto drafts, split inbox, auto labels, and auto archive keep your inbox manageable with minimal manual filing.
Collaborative documents that hold text, tables, data, and workflows in one connected surface.
Describe what you need in chat or use a visual builder, then share agents with teammates or a company directory.
