When YCS worked, it did a couple of things CommentGrab doesn't.
Its panel searched comments right on the video page. CommentGrab exports first, and you search in a spreadsheet or with AI.
It also loaded live chat replays and video transcripts, which CommentGrab doesn't export.
It takes a couple of minutes, and you don't need an account.
Add it from the Chrome Web Store. You can remove YCS afterwards.
