LaTeX and Markdown spell check in Atom

I use Atom for everything. In the last days, I have wrote a lot of text in Markdown and LaTeX, but english is not my main language so I spend some time searching lint tools and plugins to help me out.

Atoms comes with a spell-check plugin, but it does not lint every file type.

To enable Markdown and LaTeX:

text.tex.latex, source.gfm
