In Japanese, there are two distinct styles, 「ですます調」 and 「である体」. The former is considered to be polite, but it's not commonly used in scientific and/or some professional communications. However, in AI generator of Gamma in Japanese, the default mode is 「ですます調」, so it a little bit waste of time to change it into 「である体」. So, I'd like to propose to enable to set some initial prompt to change the behavior of AI when it creates cards.
Anyway, thank you for the wonderful application. Basically, I love gamma!
