Every week, Grammarly sends me an e-mail, showering me with praise about how well I’ve written that week. I’ve been using the software for more than four years; it even works in addition to the auto-correct in Microsoft Word and Firefox. As such, the company has collected a lot of data about how I type.
In yesterday’s bulletin, it was noted that I was: more productive than 94% of other users. more accurate than 83%, and using more unique words than 92% of folks.
It also notes my top three mistakes, which are usually minor matters involving punctuation. For example, Grammarly doesn’t favour an Oxford comma as much as I do; conversely, I don’t like the software’s style of writing ‘3 PM’ rather than ‘3pm’.
Which brings me to an important point that software can miss certain errors. Depending on the construction of the sentence, ‘from’ might be interchangeable with ‘form’, when only one is correct.
My best advice on the matter, which I repeat often, is to read out loud what you’ve written to see whether it flows and makes sense. If you don’t have the privacy to do that, a decent substitute is to find text-to-speech software and listen through headphones. If it detects a word out of place, it’ll be obvious when it’s read out.
Either way, spelling and grammar checkers should be used as a safety net rather than an authority, however much praise they heap onto their users.

I’ve never used Grammarly but it was interesting to read your experiences. I would say 3pm, also.

Thank you. I’ve had a couple of people in the ‘3pm’ camp, so I’m glad it’s not just me.
