Gaupol is an editor for text-based subtitle files. It supports multiple subtitle file formats and provides means of creating subtitles, editing texts and timing subtitles to match video. The user interface is designed with attention to batch processing of multiple documents and convenience of translating.

Gaupol should run on all Unix-like (GNU/Linux, *BSD, etc.) operating systems and on Windows. Technically, it should run on Mac as well, but that has not been tested nor made convenient. Gaupol's user interface is based on the GTK+ toolkit and has been designed to best fit the GNOME desktop environment.

Gaupol includes a separately installable, user-interface-independent, general-purpose Python package called aeidon for reading, writing and manipulating text-based subtitle files. See the development page for details.

Gaupol is free software released under the GNU General Public License (GPL).
