Google Scholar PDF Reader

Original Article ↗ Hacker News Discussion ↗

Google’s new Scholar PDF Reader for Chrome, which adds features like inline reference links and multiple dark modes, is met with mixed reactions from researchers. Many welcome better navigation and annotation for academic papers, but others criticize the performance and lock-in of JavaScript-based viewers, express distrust of Google’s product longevity and data collection, and instead recommend alternatives such as Zotero, Sioyek, SumatraPDF, and specialized iPad apps.

Reactions to the new Google Scholar PDF Reader

  • Appreciation for:
    • Inline, clickable references and hover previews of citations.
    • Simple, clean layout and multiple light/dark/night modes.
    • Tight integration with Chrome and Google Scholar workflows.
  • Skepticism about:
    • Performance of a JavaScript-based reader, especially on weaker machines.
    • Replacing native/OS PDF readers that users prefer (e.g., zathura, Sioyek, Sumatra, Okular).
    • Possible monetization, tracking, and use of reading behavior as training data.
    • Closed, Chrome-extension–only ecosystem and impact on embedded PDFs in other sites.

Concerns about Google Scholar and Google Reliability

  • Several users report Scholar search quality degrading (papers with many citations not appearing for obvious queries; results feeling personalized).
  • Disagreement over whether “cited by” and related-links briefly disappeared from Scholar; some insist it happened (possibly A/B testing), others never saw it. Outcome: unclear.
  • Broader distrust that Google will maintain this feature long term, referencing other discontinued products and fear of future “rug pulls” on notes/annotations.

Alternative Tools and Ecosystem

  • Local readers: frequent mentions of SumatraPDF, Sioyek, Okular, Firefox’s PDF.js, Drawboard, Skim, Preview, PDF Expert, Goodnotes, Notability, Readwise Reader, Readdle Documents, GoodReader.
  • Reference managers / platforms: Zotero (including v7 beta, plugins, sync/storage pain points), Mendeley (mixed feelings after feature removals), Paperpile, Semantic Scholar, scite, OpenAlex, various specialized apps (KnowledgeGarden, Cahier, Scholars, Synthical).
  • Some report rich personal setups combining file systems, Zotero, SumatraPDF, scripting tools, and Emacs pdf-tools/org-ref.

Reading Experience, Formats, and AI Wishes

  • Many still prefer native readers or even printed paper for deep work; others advocate large monitors, tablets, or e-ink devices.
  • Debate over PDFs vs HTML: PDFs seen as stable for archiving; HTML lauded for machine-readability and richer, semantic, interactive documents, but current tooling is imperfect.
  • Desired “next step” features include AI-based summarization, contextualization within a field, critique of methods, structured outlines, and plain-language rephrasing, going beyond mere rendering improvements.
