The new rich text editor for the Long Text attribute needs its own spell check!!
If using Chrome, there’s spell check built in, but the attribute needs a more robust spell check.
ProWritingAid offers an API (https://prowritingaid.com/en/App/API). It’s an excellent grammar check and writing style help tool for English. I find it very helpful and use it constantly (in the last couple of days I learned the hard way that the ProWritingAid Chrome Extension doesn’t play well with Infinity’s new rich text editor!).
How about integrating it in Infinity?!
