Reference management for researchers and students
Paperpile is a cloud-first reference manager and PDF workflow tool for researchers and students that centralizes citation management, in-browser PDF reading, and Google Workspace integration. It’s ideal for academics who need fast, accurate reference imports and formatted citations; pricing is subscription-based with per-user plans and a free trial, making it accessible for individuals and small labs.
Paperpile is a web-based reference manager that organizes PDFs, generates citations, and syncs with Google Docs and Drive. It centralizes literature collection using browser extensions and DOI/PubMed imports, with in-browser PDF annotation and automatic metadata extraction as core capabilities. Paperpile’s key differentiator is tight Google Workspace integration (Docs and Drive) plus a lightweight Chrome extension for one-click imports, serving researchers, graduate students, and librarians. Pricing is subscription-based with a free trial and individual/monthly or annual plans, keeping the tool accessible to individual academics and small teams in the research & learning category.
Paperpile is a cloud-native reference management app launched to modernize citation workflows for researchers and students. Originally developed with a focus on Chrome and Google ecosystem users, Paperpile positions itself as a simpler, web-first alternative to legacy desktop tools. Its core value proposition is removing friction from collecting references, attaching PDFs, and inserting formatted citations inside Google Docs while keeping a synced library in Google Drive. Paperpile emphasizes metadata accuracy, DOI-driven imports, and a no-nonsense interface that runs entirely in the browser and via mobile-accessible web pages rather than heavy desktop clients.
Paperpile’s feature set targets the core researcher needs: one-click import via the Chrome extension that captures metadata from publisher pages, PubMed, arXiv, and DOI links; automatic PDF retrieval and attachment with metadata cleanup; in-browser PDF viewer with highlights and notes that stay linked to library entries; and citation formatting with CSL styles inside Google Docs via the Paperpile > Cite menu. It also offers bulk metadata edit, duplicate detection and merging, folder/label organization, and EndNote/RIS/BibTeX export. For teams and labs, Paperpile supports shared team libraries with role-based permissions, and integrates with Google Drive so PDFs are stored in a user’s Drive folder or a shared team Drive.
Pricing is subscription-based with options for individuals and teams. Paperpile offers a 30-day free trial for new users. Individual plans are billed annually (the standard individual plan price is listed on the site and varies by billing cycle; see site for current exact monthly equivalent), while team plans are charged per user per month with discounted annual billing for institutions. The service does not offer a permanently free unlimited tier; free trial users can evaluate features but will need to subscribe for continued syncing, team libraries, and long-term storage. Educational/volume discounts and site licenses for institutions are available via custom quotes.
Paperpile is used widely by graduate students managing literature reviews and by principal investigators coordinating lab reading collections. For example, a PhD student uses Paperpile to collect 300+ references, annotate PDFs, and insert citations directly into thesis chapters in Google Docs. A postdoc uses team libraries to share 150 curated PDFs with collaborators and maintain a single canonical BibTeX for preprints. Compared with Zotero, Paperpile favors web-first Google Docs integration and Drive-backed PDF storage over Zotero’s local-first database and broader third-party plugin ecosystem, making the choice dependent on team needs and infrastructure preferences.
