Gaupol review
A capable free subtitle editor for Linux users who need core text and timing tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Gaupol is a free, open-source desktop application for creating and editing text-based subtitle files. It is aimed at people who need core subtitle work on Linux or Windows, including writing dialogue, translating content, adjusting timing, correcting common errors, and checking subtitles against video. The application supports SubRip (SRT) and WebVTT files, making it suitable for workflows built around those formats. Its GNU General Public License distribution also makes it a practical choice for users seeking an open-source subtitle editor rather than a paid service.
The feature set is focused but useful. Gaupol can handle subtitle timing adjustments to match video, and translation is supported through a separate translation document rather than being presented as an automated translation service. For review, it offers an integrated video player and can also launch an external video player. Those tools give the application a broader editing workflow than a basic text editor, while common-error correction helps address routine subtitle cleanup. Users working primarily with SRT or WebVTT files will find the format support aligned with common text-based subtitle tasks.
Platform fit is the main consideration. Linux users get the clearest match for Gaupol’s desktop editing feature set, while Windows users face a more limited experience: installers are no longer built, the latest Windows version is 1.3.1, and some functionality, including the built-in video player, does not work there. Choose Gaupol if you want a free, open-source editor for subtitle text, translation documents, timing, error correction, and SRT or WebVTT files. Choose an alternative if Windows support, an available installer, or built-in video playback on Windows is central to your workflow.
