editing

I can usually write a blog post in a few days. Day 1 is determining/researching the keyword, creating the outline, and putting it in my content calendar. Day 2 is writing and editing. Usually takes about 3 hours to write (up to 5,000 words) and an hour to edit (thanks to Grammarly). How about...

How do you edit for grammar and spelling? Do you use a tool such as Grammarly? Or do you try to do it yourself? How long does it take for you to typically edit your content?
