I'm sure not too long ago, Google Chrome was checking my grammar as I typed, underlying problematic words/phrases with a grey squiggle. This was in addition to the regular red squiggle when spell checking.
However, it is no longer doing this (version 30.0.1599.69 m) and I can find no way of enabling this?
I have googled some articles dating back to February which report this new grammar checking feature - so I don't think I've been dreaming!?
