YouTube to Doc is freaking awesome! Total lifesaver for turning videos into text. Just paste the URL → boom, you’ve got a doc. Perfect for notes or quotes. 10/10 recommend!

I tried the item removal function for an image I wanted to use in a listing. It literally gave me an error and generated nothing, but took my credits... Not nice!
