It's easy to use, the assistant is really helpful and not distracting, and the app is simple but very useful. There are some problems, like the assistant won't pop up or the "accept all" will double a word, merge with another, or just remove the space. It's quite bothersome, but I can just have to reset it from the accessibility and learn to not click "accept all" twice if it's already been fixed or just remove my keyboard before clicking back on my work. It's honestly better than Grammarly.

I am unable to tap on the words in the rephrased version in the most recent update. I tried double-tapping and press-holding on the words, but other thesaurus words did not appear. Also, can you add a feature for the history for those documents saying like if you wanted to select all of the previous history documents so I can delete all at one time instead of deleting one at a time or five at a time?

Recently, the app has been faulty. It won't grammar check unless I go directly to the app. I downloaded the app for easy access through the keyboard, so this is becoming bothersome. Another was that I hope this app will allow switching themes and perhaps adding a clipboard. Other than those, I like this app.
