I didn't find any use case where it would help me compared to using directly ChatGPT. It's usually the opposite. For example, it defined my brand voice with 3 caracteristics. So far so good but then when I want to generate any text it writes:
Caracteristic1:
Text... blabla
Caracteristic2:
Text... blabla
Caracteristic3:
Text... blabla
So I have to clean my text from the "titles" to use it. Very weird and not convenient.
Also, I don't find the templates very helpful compared to writing a prompt directly.
I'm glad it helps some people but it's not for me, I'll stick to ChatGPT.
