I've used quite a few of the Appsumo content optimisers and Robinize has one of the nicest interfaces. It's smooth and the suggestions and "inspiration" features are helpful, and you can beef up the SEO rating quite fast.

If you have an AI-Writer without content optimisation then this is a neat complementary product, just cut and paste and let Robinize guide your improvements.

I'm not sure it's better than NeuronWriter but I do prefer the Robinize UI. I think that the document limits on the tiers, especially Tier 1, are too low compared to many other offers we have seen on Appsumo.

I had a couple of questions and support was very fast and helpful.

In conclusion, if you already have a content generator with SEO optimization e.g. Frase, then you won’t find much value except for the smooth UI. If you need SEO optimization as a stand-alone or just want to check out a nice app then try Robinize.
