Compared to cheaper products like SimilarContent Pro, NeuronWriter is much more powerful. It has a beautiful UI that is pretty intuitive, and I most liked the ability to hand pick the results to optimize against. It allows you to exclude results that muddy the results. Compared to SurferSEO, the main complaint is that it's not quite as easy to use. It requires a bit more setup to start working on your article. However, it doesn't seem to have any lost functionality, and actually seems better at inserting AI driven content. I'd pay the lifetime deal price monthly if I had to, it's that good.
