6s broken, how could i possibly transfer notes under On My iPhone to a computer or iCloud or ANYTHING?

I accidentally closed my car door on my iphone six and now there's all these graphic lines and black spots on the screen, i can't see anything of the screen really. Siri barely works. I want to save my notes under On My iPhone, is there ANY possibility i could? Is there any chance my phone could be repaired?

It depends
