Marker

Marker is a markdown editor built specifically for the GNOME desktop environment on Linux systems. It allows users to draft and format documents using standard markdown syntax while providing live HTML previews. The application integrates with GNOME's user interface guidelines, offering a straightforward writing environment without extraneous distraction elements. It includes support for mathematical expressions, code syntax highlighting, and document export through Pandoc integration.

Designed for individual note-taking and documentation tasks, the software relies on local file storage and interacts directly with the Linux file system. Users can manage multiple documents within a single window interface and navigate headings via an outline sidebar. Because it targets the GNOME desktop, its visual presentation and shortcut structure align closely with native GTK applications.
