However, I'll give you a -5/10 for another tiny font size and font weight product page. Even Apple who, as far as I can tell, originated that style, doesn't go for such extremes.
There's no way anyone on a large screen is going to read the minuscule body copy.
"I really love how the tiny font almost blends into the background and forces me to squint", said no one ever.
I don't think the video background works either, it's too distracting, and makes the headline hard to read when it blends too much with the background color.
The headline is also fairly weak and lacks clarity. Your product is only tangentially about dragging and dropping. On the other hand, I can't see how you can avoid talking about bookmarking or "saving for later", which seems to be the main purpose. So I would mention that somewhere in the headline/subhead.
The fact it's in the cloud seems to me to be a point of parity at best, given that Chrome can already sync your bookmarks by itself. Same with Evernote.
Besides, the formulation is a bit clumsy given that I do not want to drop what I'm saving just anywhere. I want it to be organized. I want to drop it where I can find it.
My guess is that you mean I can drag and drop it from anywhere, but again, that's kind of a platitudinous feature these days.
The main benefit I see in the product is that it gives me a higher level of granularity as I can save sub-elements of a page directly, instead of bookmarking a whole page, or resorting to a third party, out-of-the-browser program to save and organize e.g. images independently. So it seems to allow me to save exactly what I need, more easily.
(Note that I have no idea if something similar already exists).
