I don't use the web version of Descript and the desktop version used to have the export to YouTube functionality, but for a long time it has said that the feature is coming soon. I don't understand why it was removed in the first place. It seems to me the web version and the desktop version should be identical in features. I post 40+ videos per month to YouTube and it's a pain to export to local and then upload to YouTube, not to mention the drain on my physical resources.
