Editsub vs Gaupol

EditSub is a web-based subtitle editor and management tool for changing subtitle text, adjusting timing, translating subtitles and converting formats. It works with SRT, VTT, SBV, SUB, ASS and SSA files, and exports SRT and VTT. Its AI translation supports more than 100 languages. Local audio or video files up to 10 minutes can be transcribed free without logging in; longer files and translation require credits. The AI co-pilot can flag reading-speed, timing, overlap, gap, line-length and transcription issues, and can fix or rewrite cues. Timing tools include frame-accurate adjustment, batch shifting, waveform synchronization and real-time preview. Video-to-subtitle accepts listed audio and video formats, with a maximum media size of 3072 MB; subtitle uploads are limited to 10 MB. The free plan includes 10 subtitle files. Pro is listed at $4 a year, billed $48 per year, with 1,500 credits per month.

Gaupol is free subtitle-editing software for creating and translating text-based subtitles, timing them to video, and correcting common errors. It supports multiple subtitle formats and lists SRT and VTT export. A built-in video player is available, with an option to launch an external player. Gaupol is Free Software under the GNU General Public License, with a free plan priced at free. Linux is the current availability listed by the maker, with Flatpak, source code, and packages for most popular distributions. Windows installers are no longer built; the latest Windows version is 1.3.1 and its built-in player is disabled. The integrated player uses GStreamer, and additional plugins are recommended for broader container and codec support. Optional source dependencies cover spell-checking and character-encoding detection. Gaupol includes aeidon, a separately installable Python package for subtitle-file manipulation. Documentation, discussions, and an issue tracker provide support channels.
