How We Created This List - Our Methodology

While looking for the best online grammar checker platforms, there were several things we took into consideration. First, we needed to identify the target audience. We realized that this product caters to a very large user base, which explains why there are so many options out there.
Then, we did some research by visiting the websites of the companies and went through as many reviews of grammar checker companies as we could find to get a better feel for each product.
Finally, we identified a set of criteria to help us rate and describe each of the chosen tools. These include:

  • Features: What makes the software stand out from the crowd.
  • Process: We looked at how each of the grammar checker tools operates, and how it presents its results.
  • Integrations: Which platforms the software can be used on. Is it the best grammar checker app for Android, Windows, or other platforms?
  • Educational resources and support: Some of these software solutions are also designed to help you learn and improve your grammar or writing skills. That’s why we looked at how they do that and how effective they are.
  • Pricing and extras: Our main purpose was to figure out if the products (where they had paid plans) offer good value for money.
  • Free trial: We gave extra points to software that either offers a free trial or a free plan.

If you have ever seen a YouTube video, you’ve heard about Grammarly. As one of the most popular grammar checker tools, if not the most popular, Grammarly opens our review list.
It’s one of the most used grammar checkers today, and for a good reason. It uses tons of algorithms to detect and prevent mistakes, from spelling to sentence structure.

Features

While the free plan provided by this grammar checker will cover your basics (spelling, grammar, and punctuation) just fine, it is the features of the paid plans that make Grammarly stand out. These include:

    • Fluency
    • Style-guides (the 5 major ones)
    • Formality level check
    • Plagiarism detection
    • Clarity of message
    • ToneHuman proofreading — that’s right, for a set price per text, you can get your writing proofread by Grammarly’s experts.

All these and more are the reason why Grammarly is considered to be the best grammar checker in 2020.

Integrations

While Grammarly integrates only with Microsoft’s desktop apps such as Word or Outlook, if the app you want to use Grammarly with has a web version, the Chrome extension will do the trick just fine.

Pricing

This grammar checker tool comes in 4 plans:

  • Free: No payment needed. Serves one user and includes grammar checker, spellcheck, and punctuation check.
  • Premium: Also serves a single user, but comes packed with great features, including more advanced suggestions, fluency, formality, etc. It comes with a starting price of $11.66.
  • Business: Includes all the features of the Premium plan, but covers more users (from 3 up to 149), and adds style guides, admin panels, team usage statistics, etc, to the mix. Its starting price is $12.50.
  • Grammarly @Edu: Grammarly’s service offered to Universities and educational institutions. Schools and universities can get a special Grammarly pack for their students and staff. The price is subject to negotiation.

Ease of Use

This is one more aspect that makes Grammarly one of the best grammar checker platforms around. It is almost notoriously easy to use, and not only will it point your mistakes out as you go, but it will also provide a brief explanation. It can follow you wherever you go because it is available as an add-on for chrome, and as a mobile app that will be integrated into your smartphone keyboard.

Next on our list of the best online grammar checker tools is a platform that boosts your writing proficiency in more than 40 different languages. That’s right, Ginger is considered the best online editor for international writers.
Considered to be the best alternative for Grammarly, Ginger prides itself on an equally stunning array of features in its paid plan, while providing the basics for free. The biggest difference? The Grammarly vs Ginger comparison shows that the latter brings translation to the mix.

    • Tried and tested error-catching software
    • Proofreads as you go
    • Integrations and add-ons
    • Translation into 40+ languages

Looking at the pricing options, we can see that Ginger is an affordable grammar checker, which makes it a go-to for young writers.

Scribens prides itself on being a free grammar checking solution. It provides fairly accurate checks, along with basic features.

Features

Being an open-source software apparently means that features are somewhat limited with Scribens. For the most part, they include:

    • Grammar and spell-checker

    • A wide range of integrations
      There is a lot left to be desired with Scribens, such as plagiarism checker, reporting, etc.

Grammarix is a completely free grammar checker, but does that make it the best free online grammar checker? Let’s find out.

Grammarix is a web-based tool, meaning there are no add-ons or apps to download. Everything operates from the website. It runs on a simple interface, which makes it very user friendly, even if you have never used a grammar checker before.

Features

Being a fairly simple and free website, Grammarix offers pretty standard features:

    • Grammar and punctuation check
    • Spelling
    • Misused words
    • Plagiarism checker
      There are a few more features, but it needs to be noted that they don’t always operate at 100% accuracy. This is especially true for the plagiarism checker.

Integrations

Grammarix does not integrate with other software. It is available solely as a web app.

Pricing

This is fully open-source software, meaning there are absolutely no charges for using it. However, if you try the “advanced check” option, the website will redirect you to Grammarly.

Its simplicity and the fact that there are no installations or integrations make Grammarix very easy to use, which grants it a place on our best grammar checker list.

At a Glance

Ease of Use

Since it works on a “copy-paste” basis, this is a very user-friendly tool. Probably one of the most user friendly in our best grammar checker comparison.

How to Choose the Best Grammar Checker Application for You?

When choosing the best grammar checker website or app for your needs, there are several things you need to factor in before you make the purchase (or download):

  • The volume of text

This means how much writing you are going to deliver each week/month. You may want to consider a paid plan if you are producing lots of text.

  • Number of writers

If you are writing in a team (or managing a team of writers), one of the platforms that offer team management tools and help with cross-checking texts will cater better to your needs.

  • Budget

Always a very important factor. Keep in mind that most of the best grammar checking and proofreading software offer free trials and plans. So you always have the opportunity to test it out before committing financially.

  • Integrations

This can be very important, depending on the purpose of your writing. If you want to be grammatically correct all the time, even when texting, then you need to get the best grammar checker app for iPhone or Android. Or maybe you need the best grammar checker for MS Word. Either way, integrations matter.

Benefits Of Using Grammar Checker

Just like most other tech advances, grammar checkers are here to make our lives easier. Regular use of any of the solutions from this list can benefit you in multiple ways, both personally and professionally. Here are just some of the numerous benefits of this type of software:

  • It saves time

Have you ever had a text read by a professional proofreader? It takes ages. And sometimes we just don’t have that much time to spend. With advanced algorithms and sophisticated AI, some of these programs and websites can get you exactly where you need to be in a matter of minutes.

  • They are extremely versatilе

It doesn’t matter what kind of texts you are writing, grammar checkers are there for all of your needs. From invoices to epic fantasy novels, they can deal with everything. 

  • They can improve your writing

Some grammar checkers can make you a better writer. Through algorithms made to spot out style inconsistencies and mistakes, these tools can boost your writing performance along with grammatical correctness.

  • They can help you learn a language

Some of these platforms are great for foreign language learners. They not only correct your mistakes but provide detailed explanations on why the correction needed to be made in the first place. 

  • Most of them offer free version

Almost each of the entries on our list is either completely free or offers a basic free plan. This means that not being able to pay for software is no longer an excuse for bad grammar or wrong punctuation.

FAQs

What is the best spelling and grammar checker?

According to most users, this flattering title would have to go to Grammarly. However, since the field is developing rapidly, Grammarly may find its top spot threatened very soon.

Which is the best grammar checker software?

As we previously said, Grammarly is currently the top dog in the grammar checker game. However, mostly due to its price, Ginger is a close runner-up for the title of the best grammar checker.

Is a grammar checker safe to use?

To the best of our knowledge — absolutely yes. Still, when using web-based grammar checkers, extra caution is always advisable, just like with any web-based tool. It needs to be said though, that grammar checkers are not a very common tool used by hackers or identity thieves.
