What it does

Load a subtitle file (.srt, .ass, .vtt and others) and it translates the lines using an AI, taking surrounding sentences into account so the result reads better than line-by-line machine translation. Interrupted jobs can be resumed from a saved checkpoint. The app is free but you supply your own API key and pay for the usage, which scales with the number of lines - try a short file first to gauge the cost.
