Description
Ncurator's original English pages no longer resolve; ncurator.com now redirects straight to a Chinese-only site at guanzhangai.cn/zh, which the site's own structured data lists under the name 馆长 ("Guanzhang"), with 馆长AI as an alternate name. The underlying project remains open source on GitHub under the original name, github.com/Yoan98/Ncurator, built by a developer who goes by Yoan.

The product's own tagline translates roughly to "Guanzhang, your AI work partner." The pitch is a desktop AI assistant: a user hands it a task, and it draws on a local knowledge base, searches the web, and works directly with Word, PDF, Excel and PowerPoint files. The site frames this as AI acting autonomously on a task rather than answering one question at a time; the person only has to describe what they want, such as pulling a week's meeting notes and numbers into a management report.
Two views are shown for reviewing the AI's work: a preview that shows the finished result directly, and an audit view that highlights exactly which parts of a document the AI changed, so a person can confirm the edits before sending the file on. A separate browser extension can feed bookmarked web pages into the same local knowledge base.
On cost, the app itself is free; a user connects their own AI model (the site's own example uses DeepSeek V4.1 Flash) and pays only for the tokens that model provider charges. The site emphasizes a caching mechanism: because repeated, similar tasks tend to hit a cached version of the same context, the effective per-task cost drops, with one worked example on the page showing a roughly 30-yuan task falling to about 3 yuan (roughly a 90% reduction) once cache hits are accounted for, and a claimed 30x price difference between a cached and an uncached token.
The desktop app supports Windows and macOS, including Apple Silicon Macs. Contact and community channels listed on the site include GitHub, X (@Yoan_Huang), a QQ group, Xiaohongshu (Little Red Book), Douyin and a direct email address, all oriented toward a Chinese-speaking user base.
Because the current site is entirely in Chinese with no English version live, and because it is a downloadable desktop application rather than a web app, this entry describes the product as it now operates, distinct from the English-language "knowledge base AI Q&A" framing it previously carried. Its practical audience is individual knowledge workers and small teams who want a private, local-first AI assistant for document and knowledge-base work rather than a cloud subscription product, and who are comfortable connecting and paying for their own AI model access.
