I use Grammarly, but ignore 99 percent of what it suggests. For example "US English" spellings. I'm a Brit. I won't change "doughnut" to "donut". I use the Queen's English. For a Brit to use US spelling is tantamount to High Treason.

Grammarly also does its best to extinguish my style, but I ignore those suggestions too. However, it is worth using purely to pick up on the odd typo, etc.
