Braille, Google Chrome has a built in spell-checker. You can find it under, Tools>Options>Minor Tweaks>Change font and language settings>Languages tab, spell-checker. Its really buried but you can turn it off it it bugs you.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
