>Drop any file. Get accurate subtitles.
This is my main issue with tools like these. Automated subtitles are inherently inaccurate, because much of language depends on context which you cannot get just from a brief snippet of something. This wouldn't be much of an issue if the tool was targeted at people dedicated to creating subtitles, but if you're trying to learn a new language, how are you supposed to know when the output is wrong or not?
