Sioyek is a PDF viewer with a focus on technical books and research
papers. It uses the mupdf rendering library.
Searchable
Quickly search your previously opened documents, table of contents,
bookmarks, and highlights. Sioyek can even generate the table of
contents if the document doesn't have one!
Smart Jump
You can preview or jump to references (e.g. bibliography, figures,
equations, etc.) even when the document doesn't have links. You can
also search references in google scholar with one click!
Portals
You can create portals from parts of documents to other parts which
are displayed in a second window. So when you are reading a paragraph
that is talking about a figure, table, algorithm, theorem, etc. you
don't have to keep jumping between the two locations.
Marks and Bookmarks
Mark locations with one-character symbols and then quickly jump back
to them. You can also create bookmarks which are like marks, but use a
descriptive text instead of a symbol and can be searched.
Highlights
Sioyek can highlight text with different colors. They are searchable!
Command Palette
Discover sioyek commands and shortcuts using the searchable command
palette.
Keyboard Focused
While sioyek fully supports many mouse actions, it is still possible
to use sioyek only using a keyboard. This includes functionality such
as text selection too!
Synctex
Sioyek autoreloads the document so you can preview the changes as you
edit the latex file. You can also jump between the corresponding
locations in PDF and latex files with one click.
Ruler
Use a visual ruler to highlight the line currently being read. It
reduces eye strain and combined with smart jump feature can create
previews and portals without needing to click on the reference!
Configurable
Sioyek is highly configurable. You can change all the keybinds and
adjust the behavior of the application.
Extensible
You can extend sioyek using external commands and scripts. For example
you can add OCR, translation, and text to speech to sioyek.
