What it is
Bookends is a reference-management app for students and professionals working with research. It collects, organizes, annotates, cites, syncs, shares, and publishes references across macOS, iOS, and a browser extension. The Mac app includes hundreds of searches for scholarly sources and institutional libraries, and can import references and PDFs. Its reader combines PDF annotations, notes, deep links, and searches across reference records and attached file contents. Bookends can scan manuscripts, replace temporary citations, and create in-text citations, footnotes, and bibliographies using built-in or CSL styles. Imports include EndNote XML, RIS, BibTeX, PubMed, and SenteXML, with integrations for Microsoft Word and other listed applications. Bookends Bridge connects browsers to the Mac app. MCP-capable AI assistants can search references, read PDFs, add notes and highlights, locate citations, and create bibliographies. Mac and iOS libraries sync through iCloud and can be shared with colleagues.
