These guys are have put together an impressive product. They launched initially as a Frase competitor, focused primarily on research and content briefs with minor AI capabilities. For those who may have tried the original product at launch (GPT-2), the product has grown leaps and bounds in their version 5 release.

I never owned Shortly or Jarvis, but I did test Shortly back when they had the free trial. Admittedly, the test was early in my "learning the AI dance" stage, so I can't compare fully.
However, I can comfortably say that Outranking's new "concepts" AI model (which is GPT-3 and NLP on steroids) is better than any other AI tool I've used (Frase included). Why it's better is a whole post or video, but the model consumes 3X+ the GPT-3 credits by feeding SERP results into GPT-3 to manipulate the output for more relevant content.

This part of their technology is where many people misunderstand the product. I don't think you can compare the AI to any other AI tools out there. The content is on topic and less fluffy. To a larger extent, I can even trust the AI outputs' data, facts, and statistics. Still not perfect, but MUCH better than the random "facts" many AI tools spit out.

Another game-changing piece of tech allows me to paste my source information (client info or a specific competitor post) and then let the AI use that information to generate concepts and content. Other GPT-3 AIs fail due to lack of training (anything after 2019 or very specific niche topics); Outranking's AI can still generate content.

Yes, there are character limits. All the Early Adopters have been griping, but few of us complain about the quality of the AI. Is it a perfect tool? No, the AI still generates tangential content occasionally, and I still check any hard facts the AI spits out. Additionally, the content optimization functionality of the tool isn't as robust as Frase. Frase helps me pick up topics to include in my content that Outranking does not. However, I spend much less time editing crap AI outputs with Outranking, and my time to the first draft is significantly lower with this tool.

For reference, I own Frase w/ SEO add-on, Closer copy, Rytr, Nichesss, and Marketmuse. I would return all but Frase for this tool if I could.
