I am an early supporter. This is one of the best deals here.

They keep updating the tool, fix bugs, adding new features and listen to the community. A great example how a lifetimedeal should be.

Text generation is already good and they offer many nice tools already. As well the image generation is very good out of the box.

Hope they will add a bulk text generation feature and a simple way to add some kind of retrieval to add important related information before generting a text.
Also a crawling feature for URLs and Google Serps (with country and language selection) would be a gamechanger.

oh...and an API and a WordPress Plugin would be also great. ;)

Anyway, it's already a great tool, so get it before its gone!
