Sioyek is a PDF viewer designed for reading research papers, technical books and other documents containing numerous references. It concentrates on fast, keyboard-driven navigation and tools that make moving between related sections easier.
Its Smart Jump feature can locate references to figures, tables and bibliography entries, even when a document lacks embedded hyperlinks. Overview functionality displays referenced material without requiring readers to lose their current position.
Sioyek also provides marks, bookmarks, text highlighting and portals that link different document locations. These capabilities are particularly useful when studying academic papers or navigating lengthy technical manuals.
