I use the AAAsummarize.io chatgpt plugin to summarize youtube videos. Has worked really well for me.
so many chatgpt plugins start with an "A " in their name to "rank" first in the list of all plugins. throw back to the telephone directory days :-)
I use VoxScript because the first plugin I tried didn’t work well (time-outs) and it was the second and last YouTube plugin I tried. It’s okay but sometimes I need to ask for a full transcript otherwise it will get only the first chunk of the subtitles.
