I use Grammarly with my blog and social media posts as well as everything else I type to check spelling and grammar. Grammarly works well with both USAish, UKish, and the English of the rest of the world.
Grammarly is an advanced editor that is extremely that catches most spelling errors and surprises me all of the time with its excellent grammar suggestions
Grammarly works well in virtually all programs I use such as WordPress, Twitter, Facebook, note editors, email, and many other apps.
