I've bought several different AI copy generators so far, as well as LOTS of different prompt scripts and tools. I find AdCopy.ai to be one of the quickest and easiest to use, and generates really good looking copy in no time. I love the fact that it produces three different versions on each generation because we all know testing is so important, but most just generate one piece of copy at a time. I also like how they have focused in on doing one thing and doing it well. Facebook is their jam, and the integration with the ad account takes the whole thing to the next level. Rather than trying to be a jack of all trades like most of these tools, AdCopy.ai is focused in on being the best for Facebook, not thinking solely about copy but about the whole Facebook advertising space
