I am thinking of Creating a Highly customisable word level subtitle generator for video and audio, What are the ways in which you will use it ?

Hi to all startup creators , I am thinking of creating a tool will let you create high quality subtitles with word level precision for you videos and audio files. You will be able to set the styling of the subtitles, like font size, colour of the text, active word colour, number of words per timestamp, and much more. This will available as a web app. Just upload your video or audio file and get the generated subtitles (.SRT or .VTT ) files. You will be able to create subtitles in multiple languages also. Will you use it ? Do you think a tool like this will add value to your life ?
