@dsimmerly i don't believe there is anything within acumatica but i know using google chrome, if i type something incorrectly, it underlines it in red which works as my spell checker.
I also found this on Augforums.com:

@dsimmerly as @iqraharrison48 mentioned, you could use the built-in spell checker for your browser. Alternatively, you can try Grammarly which is useful since not only does it check for spelling, it checks for proper grammar, punctuation, clarity, etc. It’s a freemium solution and the free tier covers the common use cases, while the premium features leverage their AI engine more heavily. Comparison of plans here.
There is a extension called wordtune that works similar to Grammarly. I have used it with great success.
