I tested out WriterZen, and I will start out by saying that I love the interface. Design is a huge priority for me, seeing the design of WriterZen it was a great start.

Starting out with their topic discovery, it's a great way to fast get more than 100 topic ideas based on a keyword. The ideas vary from extremely relevant, to more remotely relevant. Do however be aware that it's the Top 10 SERP on the different keywords which are showing, so do not copy / paste them. With that being said, the amount of topics and relevant keywords are really impressive.

Their Content Creator is a great start, I do know that this is their next big focus the near future which is good to hear. It has great potential and you can create SEO optimised articles. However, when I compare to Frase or BiQ.Cloud I feel there are a lot of checks they can add to enable their users to create better SEO optimised articles.

It's no secret that they use Googles API, this does however also show that a lot of the results in their Keyword Explorer are similar to other tools which are using the API as well. I hope in the future they will add their own dataset layer on top of Google to be more unique in the results.

Their Plagiarism checker works as it should, I tested out my own articles, and it found them immediately. Keep up the good work! I'm excited to follow WriterZen over the coming months and years!
