Hallelujah input app is a very powerful tool for Mac user to write words.
It can prompt the user to input some individual words that can’t spell. The application also supports to input Chinese words and translate them to English once the user wants to do.
I recommend another writing tool English grammar checker, we can visit its website: https://www.nounplus.net/
It’s very simple to use it, copy and paste text online, it will give you feedback.
We can get Hallelujah application from Github which link is https://github.com/dongyuwei/hallelujahIM
