I'm working on splitting it up in easy/normal videos. That should be do-able to assess.

I'm thinking about creating a browser plugin where you can tick a box to automatically import it into Fluentsubs. Or create an exercise from an existing video. It will take minutes before it is fully transcribed but it can be a nice way to prep your own content without people blaming me that I serve biased content.

I'm not sure though if people are willing to install browser plugins. I'm always a bit weiry with plugins that are invasive on websites like YouTube.
