The Best Spelling and Grammar Check Tools [AI Powered 2024]

April 25, 2024 365 views

Years of writing have opened my eyes to the fact that you can rarely escape spelling and grammar errors. You need an AI spell check tool whether you are a student who only needs the essay to contribute to your CGPA or a professional whose penmanship is a part of their career. Don’t forget that a grammar or punctuation error is enough to make even the most compelling writing lose its shine. 

Fortunately, writing has taken an easier turn. With many spelling and writing tools available, you do not have to worry about sending error-laden texts. These tools are reliable and can serve as our personal writing guardians, helping us catch pesky spelling and grammar mistakes and ensuring we only produce professional and polished works.

Spelling-Checking Tools Improve Your Writing

Types of Spell Check Tools

Spell check tools come in different types, and their functions differ. Yes, not all spelling and grammar-checking tools are created equal. Each tool has variable features that make it more suitable in some instances than others. Knowing the spelling tool types will enable you to choose the best ones for your needs.

Below are some types of spelling and grammar tools available for use across the board:

Traditional Spell Checkers

Traditional Spell Checker Within Microsoft Word

Traditional Spell checkers use simple algorithms to catch spelling and typographical errors. These checkers cross-reference a text to an in-built static dictionary in the software.

WPS’s built-in grammar checker is another excellent example of this software. When working in WPS apps, this spell-checker underlines misspelled words in red. This alerts the writer that there’s a problem with the word, and you can choose to correct it based on the suggestions the checker brings. You can also ignore it or add such a word to the dictionary so it doesn’t flag it as incorrect next time.

Contextual Spell Checkers

Contextual Spell Check Within Grammarly

Contextual spell checkers are trained spell checkers that detect errors while considering surrounding words. These checkers do not make mistakes solely based on a single word. Therefore, they offer more accurate suggestions tailored to the writer’s intent. They are good for detecting homophones, word misuse, etc.

Grammarly is an example of a contextual spell checker. For instance, Grammarly would recognize the context and suggest “board meeting” instead of “bored meeting” if you mistyped it in an email.

AI-Powered Proofreading Services

AI-Powered Proofreading Services Within WPS

AI-powered proofreaders leverage artificial intelligence and Machine Learning to enhance spelling and grammar checking. They are of different types and are mostly contextual as they have been trained with high-volume text, enabling them to write similarly to humans. AI-powered proofreading tools can be in-app, browser extension, or an app.

Quillbot is an example of an AI-powered proofreading tool. It can detect errors, suggest solutions, and paraphrase texts for better outcomes.

Browser Extensions and Plugins

Browser extensions and plugins are indispensable spelling and grammar-checking tools that seamlessly integrate into web browsers. They provide real-time editing suggestions. They are capable of helping writers ensure error-free online forms, emails, documents, etc. Their functions range from basic spell checks to contextual and multilingual spelling checks.

You can integrate many grammar and proofreading tools, such as browser extensions and plug-ins. For instance, Quillbot, Grammarly, and Hemmingway Editor, among others, all have browser extensions.

Integrated Writing Assistants

WPS AI Writing Assistant

Some advanced writing platforms and word processors include built-in AI spell-check capabilities as part of their overall writing assistance features. These tools often offer context-aware suggestions and can help with broader writing issues beyond spelling.

For instance, the WPS writing assistant works across all WPS office tools, including Doc, Sheets, and Presentations. So, whether you are collating a dataset for your work or making a presentation for your class, you do not need to leave the WPS app to have error-free writing.

Which kind of Spelling and Grammar checker should you use?

Varieties enable choice, allowing us to explore without limitations. However, there is also the challenge of choosing among available options. With each spelling and grammar checker presenting their uniqueness, settling for one may be dicey.

Below are some key factors to consider before choosing the right spelling and grammar check tools:

  • Accuracy

The primary purpose of a spelling and grammar check tool is to achieve the accuracy that can’t be attained when using naked eyes to proofread.

Check the tool’s reliability in detecting and correcting spelling, punctuation, grammar, and stylistic inconsistencies. Also, consider its speed and resource usage.

  • Language Support

Ensure the grammar and spelling checker supports the language you primarily use. Further, check the dialects it supports and ensure it is a perfect fit for you.

Some spelling checkers work better with some languages than others. Also, you can opt for a multilingual spell checker like LanguageTool if you are working on a text that contains more than one language.

  • Integration

Consider how seamlessly the spelling checker integrates with your current workflow. Some tools work better on some apps and browsers than others.

Consider getting a tool that integrates seamlessly across the board or works specifically for your needs. For instance, if you often work with WPS tools, it is a no-brainer that the WPS AI spell checker is your best bet.

  • Feedback and Suggestions

Catching and correcting the spelling error is not enough. Using a spell checker that gives feedback will help improve your writing. With the suggestions, you know what to look for in your forthcoming works and avoid making the same mistakes over and over again.

  • User-Interface and Ease

Choose a spelling checker with an easy, intuitive, and straightforward user interface. This will enable you to work faster rather than trying to spend precious time figuring the tool out. Choose a clean and clutter-free interface that does not disrupt your workflow.

  • Additional Features

Check and choose the additional features the grammar and spelling tools have. Some spelling and grammar checkers offer additional features like plagiarism detection, readability analysis, and writing statistics.

Consider which of these other features you need and choose a spelling and grammar checker that is a one-in-all tool for your needs.

  • Cost

Finally, consider the cost of a grammar and spelling checker before choosing one. For instance, most grammar and spelling tools, including Grammarly and the WPS AI tool, offer their basic functions for free.

However, you may need to pay for advanced and in-depth editing options. Check how comprehensive their free features are. Also, check if the advanced features only need a one-time payment or if you need to subscribe monthly or yearly.


  • Should I trust the suggestions of AI spelling checkers?

Many AI spelling checkers can catch typos and other errors in your writing. Their functioning is based on algorithms trained on a high volume of datasets, making them quite accurate.

However, they are AI tools and are not infallible. Many factors can influence their accuracy, including context and creative word use. Therefore, you should also employ your human judgment to proofread after using an AI tool.

  • Are there any AI spell and grammar checker tools integrated into Microsoft Word?

Yes, Microsoft Word has an in-built grammar-checking tool. This AI-powered grammar-checking tool functions extensively within the Microsoft Office ecosystem.

  • Are these AI spell and grammar checker tools free?

All the spell and grammar checker tools listed above have a free version. The free versions offer basic spelling and grammar checking, while the paid versions offer additional features.

For instance, WPS AI is the cheapest of all tools in this article, going for $2.99 per month, while ProWritingAid’s annual subscription starts at $70. Hemmingway, on the other hand, is not a subscription service. However, it has a one-time payment of around $20, depending on what you want.
