I see this being useful in two situations: either you're a solopreneur and you outsource your content marketing to the tool with just a light revision pass, OR if you already have a content team, let them run wild with the tool to overcharge brainstorming and overcome the "blank page syndrome", which should make them at least 2x as productive.
In any case, it does deliver on the promise, and it's getting better every day (you can see the product changing in front of you whenever you log in, I swear)
