SubtitlesDog
SubtitlesDog is a subtitle translation and generation platform built for filmmakers, educators, and video creators who need to reach audiences in other languages. Upload subtitle files or videos, pick a target language, and get translated or auto-generated captions ready for export in common formats like SRT, VTT, and ASS.
What sets it apart is how it handles long-form content. Instead of translating line by line in isolation, SubtitlesDog reads the full script first to build a style guide and lock terminology for character names, places, and key terms. Each segment is then translated with surrounding context, which helps keep tone and naming consistent across an entire film or series.
The cloud app supports 100+ languages, 13+ selectable models including GPT-4o and Gemini, and 20 genre-specific translation modes for film, anime, and documentary content. Creators who want local processing can also deploy NAS-Subtitler via Docker to generate subtitles on their own network storage.
