Article versions of videos

I cannot focus on a video, and transcripts are even worse, so I often miss vital concepts if they are only presented in video format. Having articles that explain the same concepts as videos (maybe a tab below the video next to comments section) would be useful. You wouldn't have to remove transcriptions, just provide an alternative. I am a middle school student who was assigned pre-algebra, and not having the anything to consult is dropping my grades. I have ADHD and I can read faster than people talk, so I think articles that explain the same concepts would really be a boon.
