Useless if you know what you are doing
This tool takes you through hundreds of (sometimes poorly formulated AND/OR not suited to your purpose) questions.
Those questions come basically in two types :
A) marketing questions for someone who does not really know how to do marketing.
You will define your niche, your target, your buyer persona, etc. Do you need this tool to do that? No. You need to know what you are doing. If you are new to marketing and know nothing, this tool will tell you what you need to do, in short form. I think it would be better to read a book or two about the topic and then do your own stuff.
B- Questions aimed at generating content.
These questions will ask you how to organize the document, how to structure things etc. If you know how to do this, you don't need this tool. If you have no idea what writing is, perhaps it's helpful but I would suggest getting an online course about copywriting, or a book.
This software gives the false impression that it has lots of features because you have to fill many fields. But the results are poor, poorly formatted, and are basically useless to someone who is an experienced professional.
In a review, someone mentioned that it was necessary to spend weeks filling the questions before getting good results. I think it's a waste of time really.
