Sioyek is a keyboard-focused PDF viewer designed for reading textbooks and research papers. It offers smart jumps to references, portals for viewing figures alongside text, searchable highlights and bookmarks, and Synctex support for LaTeX workflows.
Use cases
- read research papers with quick jumps to bibliography and figures
- view a figure in a second window while reading the text
- search and manage highlights and bookmarks across PDFs
- preview LaTeX-compiled PDFs with Synctex jump support
- generate a table of contents for PDFs that lack one
- read technical books with a visual reading ruler
- extend the viewer with OCR, translation, or text-to-speech scripts
When to choose
- you read academic papers or textbooks on a desktop and want fast keyboard-driven navigation
- you need Synctex integration for LaTeX editing workflows
- you want searchable highlights, bookmarks, and portals in a lightweight native viewer
When to avoid
- you need PDF form filling, signing, or annotation collaboration features
- you want a mobile or web-based PDF reader
- you need a general-purpose document manager rather than a viewer
