I have tried a plethora of AI tools out there, most of them generate decent usable results but you always need to edit them to make it meaningful. Used Peppertype.ai a couple of times now and I'm impressed with the quality of the results. At first, I was skeptical about trying out another AI tool, but I've seen that it can take my ideas and turn them into high quality content. I'll definitely continue using this tool because of the results I've seen in my own campaigns.
If you're looking for an AI tool, I would suggest you to go for this. If anyone can come close to Jarvis, I would say this is it. My only beef would be the 40k limit, I think for tier 3, it should be at least 100k. Also I wish the support was more responsive, It's been more than 24 hours and still now haven't heard from them. I think it's due to the rush as it came out on appsumo recently, so I wouldn't worry too much. This is definitely going to be a keeper.
