Papers

Yes — Papers and ReadCube are the same product. ReadCube acquired the Papers brand in 2016 and now markets the combined service as 'Papers by ReadCube.' Pricing, features, apps, and support are identical whether you visit papersapp.com or readcube.com. We cover both because each brand still has its own distinct audience — ReadCube tends to attract corporate R&D users while Papers has more academic users from its original Mac-focused history.

Papers excels at PDF reading and annotation — the reader is widely considered best-in-class, with smooth highlighting, sticky notes, and search. For academics specifically, the Word/Google Docs citation plugins, the 40% academic discount, and SmartCite for inserting references while writing make it a strong fit. It also handles 'match' lookups — drag in a random PDF and Papers finds and fills in the correct metadata automatically.

Yes. Papers Pro includes an AI assistant that chats with single PDFs or up to 20 articles at a time. You can ask questions, get summaries, and extract themes across a batch of papers. Papers Essentials includes basic AI chat per article. This is integrated into the reader, so you don't need to upload PDFs to a separate service like ChatPDF or Humata.

With the 40% academic discount, Papers Essentials drops to approximately $4.20/month or $39/year, and Papers Pro drops to $8.40/month or $78/year. You need a valid academic email or student ID to qualify. This brings Papers close to the effective cost of Zotero's unlimited storage tier ($120/year), while giving you a more polished product with native AI.

Yes. Papers has dedicated apps for iOS and iPadOS with full support for reading, highlighting, and annotating PDFs with Apple Pencil. Your library syncs in real time with the desktop and web apps. Many researchers prefer the iPad experience for reading long papers on the couch or in meetings, then switching to Mac or Windows for citation insertion during writing.

Papers supports importing from EndNote via RIS and BibTeX files, but there's no live sync between the two. If you're migrating from EndNote, you'd export your library as RIS, then drag it into Papers. Papers keeps metadata, tags, and collections intact during import. Many users report cleaner metadata post-import thanks to Papers' automatic metadata enrichment.

Papers has a more modern interface, stronger PDF reading experience, and built-in AI chat. Mendeley is free (with limited storage) and deeply integrated with Elsevier's Scopus and ScienceDirect. If you value polish, iPad support, and AI features, Papers wins. If you prefer free, accept Elsevier ownership, and need tight ScienceDirect integration, Mendeley is still fine. Both support Word and Google Docs.

Yes. Papers subscriptions can be cancelled at any time from your account settings. If you cancel, you retain read-only access to your library and can export everything via RIS or BibTeX to another reference manager. Papers doesn't lock you in — your data is yours, which is an important difference from some older research SaaS products.
