The Flacked developers seem to have caught onto what many other services haven't, that there are limitations of GPT-3 that limit its use to assist with drafting anything other than very generic or generalizable longer-form content (i.e., anything that requires a progressive building of ideas to deliver a rational conclusion. This writing assistant uses a hybrid of GPT-3 with their own AI they call DaVinci. It's still in development, but things have been developing quite quickly. It seems like almost every week there is something new or improved. The summarized tool currently already is exceptional and is by itself worth the cost of the lifetime deal, especially if you do anything like literature reviews or need to condense down your own writing even. I'd get the lifetime deal now while you can...this is going to pay for itself over and over (now even, but especially as it matures). Also, for what it's worth, the support is staffed by real people who are friendly and seem to care about the work.
