How to choose a grammar checker software
Writing is regarded as art – it requires perfection at every level. If writing is an art, the master that carves it is the grammar. As there are numerous grammar checkers available to you, here is how to pick the most suitable and best grammar checker tailored to your needs.
Extensive compatibility
You should always be able to use grammar checkers no matter the operating system or device you use. Grammarly is a perfect example of this. It’s a fantastic grammar checking tool that offers extensive compatibility and is available to use on multiple systems and devices. It’s perfectly compatible with iOS and Android, you can use it as a desktop app for Windows and Mac, and it offers extensions for Google Docs, Chrome, Edge, and Firefox.
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 proofread 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 checkers and punctuation tools offer a variety of pricing options. Some of the basic grammar checker 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 checkers 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. Each tool offers the same core features as grammar checks, expert spelling, sentence checker, writing style, punctuation, and originality checker. 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 best grammar checkers, 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 and Grammarly are grammar checkers that provide integrations with applications such as MS Office, Outlook, and Google.
Best of the best
Students copy editors, and even professional writers use grammar and copyediting tools to improve their writing and to ensure quality in their write-ups. There are several reasons why people use grammar software.
Bloggers use grammar checkers to make sure their writing is free of all errors and are quickly accepted by the website editor.
Teachers and students also use these platforms to make sure that they are issuing and submitting the right essays and content. Even website developers use the tools to improve the writing of web copy and to attract more visitors to a website. Quality writing and best grammar practices can instantly improve the credibility of a website.
The grammar checker tools improve the worthiness of a text with robust grammar and punctuation solutions. Some of these tools are equipped with AI capabilities to ensure smart learning and give better error-free suggestions for write-ups.
Best for grammar check
Grammar checkers are the key to avoiding embarrassing grammatical errors in your papers. Regardless of your academic level or expertise, if your writing has mistakes, your credibility goes down.
