Writing statistics generation

In many cases, writers are commissioned to create documents that have to follow strict standardization and format. As a writer, it’s essential to know if the document you have prepared has met those expectations. It’s extremely helpful if the grammar checker tool you use to proof the text generates in-depth statistics. That’s why it’s important to choose a tool that helps you identify statistics like word count, paragraph length, and average reading time.

Pricing

Online grammar and punctuation checker tools offer a variety of pricing options. Some of the basic online grammar check tools are entirely free to use; for example, Online Correction. Still, most of the advanced tools come either with a free version with limited features, or a premium/pro version that comes at a cost. Depending on how often you write and need to check over your work, the premium versions of these grammar check options are generally cost-efficient if you opt for the longer subscription terms.

Software features

Each specific grammar check tool comes with a particular set of features attached. Consider what you need, how you are going to use the software, and what features are offered by each option before you make your final decision.

However, particular tools come with additional features like writing stats, vocabulary, and proofreading. Make a list of all of the features that you need, find the perfect solution within the offered tools, and improve your writing.

Third-party integrations

In case you want to use one of the tools to improve your blogging skills, ensure that it integrates seamlessly with WordPress and other third-party applications. Not every grammar check tool offers this feature, and it could save you a lot of time and effort along the way. For instance, ProWritingAid is a grammar tool that provides integrations with applications such as MS Office, Outlook, Google Docs, Scrivener, and Final Draft.

Best of the best

Students copy editors, and even professional writers use grammar and editing tools to improve their writing and to ensure quality in their write-ups. There are several reasons why people use grammar software.

  1. Writing in English is difficult for everybody who is not strong in the English language. Sometimes you might think that you have written a perfect post but did you know that small mistakes can give away to the charm of your writings. So, it is wiser to use Noun Plus grammar checker tool.

  2. I use Grammarly and I particularly love the features. It works both on my phone and pc and it has significantly improved my writing skills. I totally recommend them to everyone who really wants to get serious with professional writing.

  3. Wow. This list has everything and I’m not even sure which to pick anymore. They all have amazing features and I’m sure they will work just as I want. Maybe I’ll try the Grammarly since I heard a lot of good reviews about it.

  4. Grammarly is the best. I have it as an extension in Chrome and also in my MS Word application. It has made writing a lot easier and the fact that I get reasons and explanations on each error is enough to improve my vocabulary and writing.

  5. I’ve used like 4 of the tools on this list and they all delivering the expected results. If you write professionally, or even for yourself, you may want to have one of these to make the whole thing a lot easier and faster for you.

  6. I have no problem with grammar, being a college English teacher. But I am an abominable speller. So I need a spellchecker that is 50 times better than the ridiculous one that comes with WORD, which is beyond belief stupid and idiotic! I also don’t know how to download a superb spellchecker that will automatically open in Word every single time without me having to do anything special. I’ve tried following online directions, but I just don’t understand them, and they don’t function for me.
    Suggestions for a smart editor that is dim about spelling and computers??

  7. For years I have been stalling trying to write a book but didn’t have a clue of how to put together the manuscript because I had major problems with grammar, spelling, and simply putting a manuscript to begin with!

  8. Thank you Anja for this great list of grammar checker tools! I’m using Ginger Online and for a single payment of $40, you can get it for life.

  9. For all the mistakes, Grammarly will give you an explanation of what you did wrong and offer to improve or replace errors. Great tool for a small price!
