Now for anyone who is into fiction writing, let me guide you through all the features that you get with this program.

Do note that the tool offers a $1 free trial for 14-days. Apart from that, there’s no free plan.

As the software is very niche-specific, I couldn’t recommend it to everyone who is reading this.

For generic writers, you can always go with Grammarly or Ginger software.

The first one is Free Check; this checks all the grammar, sentence, and style errors.

Later, the tools suggest all these errors in different color codes so that you can understand which error it is that you need to work upon.

The second one is the Deep Check; it checks some of the advanced grammatical errors like dangling modifiers, undecent sentences, and passive voice.

However, when you click on the Deep Check button, you’ll be redirected to Grammarly. I don’t know why they are doing this on their website.

So, if you want to check only the basic grammar and punctuation errors, do check out GrammarCheck.

Otherwise, there are other great alternatives in the list which you can try out.

With the paid plan, they have some advanced features like directly publish content to WordPress & Medium, no internet connection required, functionality to directly export your files in .doc format, and many more exciting features.

Although the free tool is excellent for beginners, you cannot solely rely on it as your only proofreading tool. The reason being, it is not a complete software in itself if you’re a full-time professional writer.

For that, you need to go with either Grammarly, WhiteSmoke, or the GingerSoftware.

After clicking on the “Analyze” button, I quickly got two messages; they are as follows:

  1. Your sentences are somewhat shorter than usual.
  2. You use considerably fewer commas than is typical of academic writing.

Well, to clear my doubts, I rechecked it this time with new 1000 words of content, and sadly, the tool shows me the same errors.

So, I wouldn’t recommend this tool to anyone. You can only use this tool if you don’t have any money but still want to check the errors in your document.

I also saw this horrifying image from the website itself.
