I recently stumbled upon this proofreading option within the profile options in WordPress. I tend to write a post when the moment strikes and even though my computer’s OS picks up on most typos, I am loving the build in option to proofread a post before publishing.
To activate the option hover over your name on the upper right corner of the window and select “Edit My Profile.”
Locate the section for Proofreading and make a selection of having your post proofread before you publish a post and/or when you update a post.
I tried it out on my last post and after I clicked “Publish” a window popped up asking if I wanted to review the spelling/grammar errors found. All of the items in question were underlined in red and very easy to find.
