AI 产品解读PubMed reading companion that enriches journal article listings with impact factor, predicted impact factor, JCR/CAS rankings, CAS early warning alerts, and provides tools for filtering, sorting, collection, and sci-hub full-text links
Researchers browsing PubMed lack quick access to journal quality metrics (impact factor, ranking zones, alerts) alongside search results, making it time-consuming to assess publication quality. This extension overlays these metrics directly on PubMed search pages and article pages.
User installs extension and browses PubMed. On search results pages, the content script (ncbi.min.js) extracts journal abbreviations, sends them to the backend API (shengxin.ren/note/getJifByAbbr), and enriches each result with color-coded impact factor, JCR/CAS zone badges, and CAS warning tags. Users can filter results by IF range or sort by IF. On individual article pages, sci-hub links and PubPeer comments are added. Optional login to note.sangerbox.com enables history saving and journal collection features.

- 目标用户
- Chinese biomedical researchers and academics / Researchers who use PubMed for literature search / Graduate students evaluating journal quality for manuscript submission
- Code is minified making exact control flow harder to trace, but key patterns are clear
- Cannot verify whether the shengxin.ren API returns data without a valid token (code sends token but doesn't explicitly handle missing token for getInfoByAbbr)
- Cannot verify the note.sangerbox.com web service's own paid/free status—only the extension itself was analyzed
付费分析未识别到付费功能
No evidence of paid features, paywall, subscription, billing, or upgrade flow in the extension source code. No payment platform integrations found. All core features (impact factor display, JCR ranking, CAS ranking, CAS alerts, filtering, sorting, journal search, sci-hub links) are implemented without any gating logic. The 'pro' keyword matches are generic CSS class names from Font Awesome, not paid feature indicators. The extension appears to be a free tool for the research community.

- Login exists at note.sangerbox.com for optional features (收藏/collect, history saving, personal center), but the core PubMed augmentation workflow works without login. The extension fetches journal impact factor data, JCR/CAS rankings, alerts, and sci-hub links regardless of auth state. The popup shows a login button, but it can be dismissed and the extension functions on PubMed pages without authentication. Token is read from cookies on note.sangerbox.com domain—if absent, features degrade gracefully (e.g., saveHistory returns a default response). The API call for 'getInfoByAbbr' sends an empty/undefined token if not logged in and still processes results.
