Is this really aimed at the smaller businesses, or is it aimed at the big businesses who want to cut down their marketing department?
Thing is at that scale cutting down on marketing with slop has huge implications. It's not like this thing blew he ceiling, it just lifted the floor.
I tried this out, and the stuff it produces is just simple text overlaid nicely on images you supply. If you have a designer, it'd take 60 seconds to knock one of these out, plus you'd already have a style guide that this app wouldn't follow closely enough to use. This is definitely for small businesses.
Obviously both parties will have access to the tech, but I don't see giant brands just using something like this to hack an ad campaign. Either way it doesn't really matter. It just levels the playing field
