Grammarly solves all of your typo problems in a second.
When you use grammarly, they put some kind of advert for youtube, so when you watch youtube videos, it will stop and their advert will start. Note, this is not a youtube ad, this is an ad directly from them.
Good product, bad adverts
Very very bad adverts
The browser extension is a must have, but I regularly pass my emails through this, or draft them in it just to catch dumb mistakes and make noticeable grammar improvements on the fly
Best way to quickly check grammar quickly after writing, or for drafting anything important.
Not as convenient as the browser extension? I've never had anything to complain about.
