Thanks for the invitation my friend. This topic has become very controversial in Steemit, as it is thought that unscrupulous users can use it to create texts and be rewarded for a job they have not done. The truth is that the tool itself is good and can allow us to create a text without argumentative flaws and can allow us to make corrections in real time. The bad thing is when it is used unethically to do the work that the creator should do. And it is not a rumor, at the end of the experimental phase it will become a paid application, however, due to its popularity and the need of material for development, surely they will create a free version with some conditions. Great publication, success in the contest!
