How to choose a Grammar Checker

With so many grammar checkers available, finding the most suitable and best grammar checker tailored to your needs can be a challenge. 

Here are some tips to help you select the right grammar checker.

Extensive Compatibility

Regardless of the operating system or device you use, grammar checkers should be available to you. For example, Grammarly is a fantastic grammar checking tool that offers extensive compatibility. It can be used on multiple systems and devices, including iOS and Android, as a desktop app for Windows and Mac, and through extensions for Google Docs, Chrome, Edge, and Firefox.

Writing Statistics Generation

Writers are often commissioned to create documents that must follow strict standardization and formatting guidelines. It’s crucial to know if your document meets these expectations. Therefore, it’s essential to choose a grammar checker tool that generates in-depth statistics, such as word count, paragraph length, and average reading time.

Pricing

Online grammar checkers offer a range of pricing options. Basic grammar checker tools, such as Online Correction, are entirely free. However, most advanced tools come with either a free version with limited features or a premium/pro version that comes at a cost. If you write frequently and need to check your work often, the premium versions of grammar checkers are generally cost-efficient if you opt for longer subscription terms.

Software Features

Each grammar check tool comes with a specific set of features. Consider your needs, how you will use the software, and what features each option offers before making a final decision. Each tool offers core features, such as grammar checks, expert spelling, sentence checker, writing style, punctuation, and originality checker. However, some tools come with additional features like writing stats, vocabulary, and proofreading. 

Third-party Integrations

If you want to use the tool to improve your blogging skills, make sure 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 and Grammarly are grammar checkers that provide integrations with applications such as MS Office, Outlook, and Google.

Although there are plenty of Grammar Checker Tools out there we didn’t include all of them because they didn’t align with the objectives for this particular article conserning free plans and pricing and suitability for Growing an Online Businesses in particular.
