My raw reaction (emphasis on raw):

looks like Quiver

is it for code?

"collaborative notebooks" ok so it's for writing

"get started today" and do what?

ok it works great on mobile and some other devices

eyes to image

you can talk, cool and you can link stuff and add files

so it's not a notebook but a chat?

eyes to "block-lower"

I can create notebooks... what the hell are notebooks?

store stuff

stay up to date... okay? it tells me the current time? it's a clock

eyes to footer nice, it's made with love... I think...

click on heart... uh, ok, I guess it's love. Perhaps.
