Amazon is changing it's policy as AI takes root in our collective writing society. This means any AI content must be labeled, which can be daunting. There are two levels, too. AI created and Ai Assisted.
Though it is uncertain as yet, many feel that using Grammarly, or even Spell Check is AI assisted. I'm rethinking some of my cover art as it is somewhat AI assisted, and though Amazon has not said a word about Covers, they could come after it when the dust settles.
Better to be safe than sorry.
