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 think Slidely is the only tool that has worked for me when creating my client presentations. The presentations aren't web pages or images like the other tools but actual PowerPoint slides which I really like.

Well, it did give me an insanely good image, but you only get one free trial, i.e, generate one image for free. And the model is costly for someone who wants free AI tools. But it does the job if you're willing to pay.

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!
