Spellar.ai does a great job. There’s others out there for Mac but I like Spellar’s calendar integration.

Interestingly, their initial raison d’être was to help with English pronunciation and speaking speed, giving you real time feedback. They’ve downplayed this in recent releases, but the functionality is still there. Though, I’m a native English speaker and it always flagged me as pronouncing words incorrectly even though I’ve got little regional accent (I’ve been told this by others, not just my opinion. I had a speech therapist as a mother, hence little accent)
