NextPaper is a Zotero companion that turns your library into a reading queue. Zotero is great for collecting papers, but it’s easy to lose track of what to read next. NextPaper gives your library a simple structure you can actually work through. Browse your collections, pick papers that matter, and add them to your NextPaper list. When you finish reading something, mark it as read and move on. Your progress is reflected directly in Zotero, so everything stays in sync. See the essentials at a glance — title, authors, abstract, and publication — without needing a desktop app. Designed for researchers who already use Zotero. There’s no new account to create. Just connect your library and start organizing your reading. Your data stays yours. NextPaper uses secure OAuth to connect to Zotero and doesn’t store your password or your library content.
