Grammar checker built into Google Docs

Woke up this morning to a nice surprise in my Google Docs (personal and school). It is very similar to spelling (however it is blue). You can access the suggestions by selecting 

• Tools
• Grammar and Spelling
• or Ctrl + Alt + X 

I will say, it is not perfect as I typed numerous sentences with grammatical errors and it did not pick them up.

However, it is a step in the right direction.

Embedded below is a picture, a GIF, as well as a 48 second YouTube tutorial.

Take care,

Brad
