10 Best AI Grammar Checker Tools for 2024

Writing well isn’t always as instinctive as speaking. In conversation, minor errors often go unnoticed, with our brains smoothing over any linguistic bumps. But in writing, each word is scrutinized, and small errors like ‘that’s there department’ instead of ‘their department’ can disrupt the flow and impact of our message.

Enter AI grammar checkers – more than just a typo fixer, these tools refine your writing style to ensure clarity and precision, whether in business proposals, blog posts, or emails. However, not all grammar checkers are created equal. It’s about choosing one that complements your unique style and meets your communication goals.

You can tailor the grammar checker to assess your text according to different criteria. This includes the type of domain, intent, audience, and formality.

In the editor, Grammarly’s AI will suggest sentence rewrites on double clicks. I’ve found it somewhat helpful, but it should be taken with a grain of salt; they’re just suggestions and may not enhance your writing.

Named after the renowned Ernest Hemingway, the tool is a grammar checker that takes after his philosophy towards writing. He takes a straightforward approach with as little fluff as possible, removing redundant adjectives and descriptors, preferring to write plainly instead (unlike my own).

This style of stripping down the writing so it’s less dense and easier to read is what makes Hemingway distinctive from the other tools on this list. It’s an AI tool that focuses on enhancing readability and simplicity in writing. Even the editor interface is designed to be a distraction-free environmentso you can focus on writing and editing.

Some users might prefer this approach and feel like this app creates bold and clear prose by highlighting complex sentences and common errors. Others may feel it’s overly restrictive.

It’s a free app, except you have to use it from your browser. The downloadable software is available for $19.99 as a one-off payment – not that steep compared to the other grammar checkers. It’s worth testing out in the browser to see if you prefer this approach.

There are all sorts of reports you can tap into, such as your content Flow chart, a breakdown of your vocabulary and word usage type. And it’s completely free.

For shorter-form content like blog articles, Slick Write will do a solid job at spotting grammatical mistakes and punctuation errors. However, if you need to proofread longer documents like a novel, other tools might serve you better due to the character submission limit.

Also, there isn’t a spelling checker which is a bit unusual for tools in this category. Slick Write focuses solely on improving grammar, albeit does a good job at that.

Scribens offers insights into your writing with its statistics feature, which includes word count, Flesch index, and more, helping you understand the impact of your words. However, it doesn’t show an overall score like other tools do.

That might not be a terrible thing, as we can be too focused on hitting a higher score rather than improving our actual writing.

On top of being a good grammar checker, Scribens supports both English and French, making it a versatile choice for a broader audience.

While it picks up basic issues fine, that’s all you can expect from this free tool. It doesn’t come with a plagiarism checker and lacks any statistics or reporting.

GrammarCheck is ideal if you’re in a hurry and just need to throw your copy in a checker to pick up any glaring issues. Best use cases would be for emails, social media posts, or other short-form copy.

What Makes the Best AI Grammar Checker and Rewording Tool?

Choosing the right AI grammar checker or rewording tool can feel like trying to find your way through a dense forest. There are so many options, each promising to be the best companion for your writing journey. But what really makes an AI tool stand out from the rest? Let’s break it down, step by step.

Accuracy: The Non-Negotiable Foundation

The cornerstone of any AI grammar checker is its accuracy. It’s not just about catching the obvious typos; the best tools understand the nuances of language. They can distinguish between homophones (like “their” and “there”) and can navigate complex grammatical structures.

When it comes to rewording, the tool should offer suggestions that maintain the original meaning while enhancing clarity and readability. You want the AI tool to be as good as vigilant editor by your side who scribbles your whole document in red to make sure you’re publishing quality work (just try not to take too much offense).

Contextual Understanding: Beyond the Basics

A top-notch AI tool doesn’t just understand words; it grasps context. It’s not enough for a tool to be a grammar guru; it should also be a style savant, offering suggestions that fit the tone and purpose of your piece.

Whether you’re writing a formal report or a casual blog post, the tool should adapt its recommendations accordingly. This contextual awareness is what elevates a good grammar checker to a great one.

User-Friendly Interface: Ease of Use is Key

The best AI tools don’t require you to have years of coding experience to make the tool work. They should be easy to use, with a clean, intuitive interface. After all, what’s the use of a powerful tool if it’s a hassle to navigate?

Features like one-click corrections, easy-to-understand explanations, and a seamless integration with your usual writing platforms (like email clients, word processors, or content management systems) are what make these tools not just helpful, but make it seem like you couldn’t work without them.

Personalization: Adapting to Your Style

Every writer has a unique voice, and the best AI grammar checkers recognize this. They should offer customization options, allowing you to set preferences for your writing style.

Whether you prefer Oxford commas or want to avoid passive voice, your AI tool should be able to tailor its suggestions to match your personal style guide.

Learning and Evolving: The AI that Grows with You

The best tools learn from their interactions with you, evolving and adapting to better meet your needs over time. They remember your common mistakes and preferences, making their future suggestions even more on-point.

Over time, the tool should evolve beyond just suggesting basic writing suggestions and provide more tailored advice based on previous corrections it made in your other work.

Comprehensive Feedback: More Than Just Corrections

Great AI grammar checkers don’t just point out errors; they educate you. They offer clear, concise explanations for their corrections, turning each error into a learning opportunity.

This feature is invaluable for those looking to improve their writing skills over time, not just fix a one-off mistake.

Speed and Efficiency: Saving Your Precious Time

In today’s fast-paced world, time is of the essence. The best AI tools work quickly, scanning your document in seconds and providing immediate feedback.

This efficiency ensures that your writing process is smooth and uninterrupted, allowing you to focus on the creative part of writing without getting bogged down by the technicalities.

Conclusion

FAQS

What is an AI Grammar Checker?

An AI grammar checker is a software tool that uses artificial intelligence to analyze written text for grammatical errors, spelling mistakes, punctuation issues, and sometimes even style and tone inconsistencies.

These tools are designed to help writers improve the quality of their writing by providing instant feedback and suggestions for correction. They work by comparing the text against complex linguistic rules and patterns.

Some advanced checkers also offer context-specific suggestions, adapting to different writing styles and purposes.

While they are a powerful aid for writers of all levels, they are not infallible and should be used as a complement to, rather than a replacement for, human judgment and editing skills.

What is the best AI tool to check grammar?

Determining the “best” AI grammar checker depends largely on individual needs and preferences.

Tools like Grammarly and ProWritingAid are widely praised for their comprehensive features, offering detailed grammar, punctuation, and style checks.

Hemingway Editor is favored for its focus on readability and sentence structure, while Ginger and Scribens are known for their multilingual support.

The best tool for you will depend on specific factors like the type of writing you do, the level of detail you need, language support, and whether you require additional features like plagiarism detection or integration with other software.

Does ChatGPT check grammar?

ChatGPT, developed by OpenAI, is primarily an AI language model designed to generate human-like text based on the input it receives. While it can assist with grammar and syntax to a certain extent, its primary function is not as a dedicated grammar checker.

It can provide suggestions and help with rephrasing sentences but does not have the specialized capability to perform detailed grammar checks like dedicated grammar checking tools.

Therefore, it’s advisable to use ChatGPT in conjunction with a specialized AI grammar checking tool for more accurate and comprehensive error detection and correction.

Can AI Grammar Checkers Replace Human Editors?

AI grammar checkers are powerful tools that can significantly aid in the writing process by catching a wide range of errors and offering suggestions for improvement. However, they cannot fully replace human editors. Human editors bring context understanding, creativity, and nuanced judgment that AI currently cannot replicate.

While AI checkers excel in identifying technical errors, they may struggle with understanding context, subtlety, and intent in writing. For works requiring deep understanding, creative input, and complex judgment, human editors remain indispensable.

Are AI Grammar Checkers Reliable for Academic Writing?

AI grammar checkers can be a valuable asset for academic writing, offering significant help with grammar, punctuation, and basic style consistency. They can assist in ensuring that academic papers are free from technical writing errors.

However, academic writing often requires adherence to specific formatting and stylistic guidelines that AI tools might not fully accommodate. Additionally, the nuanced argumentation and complex structure typical of academic writing might sometimes be beyond the scope of these tools.

Therefore, while AI grammar checkers are reliable for basic checks, they should be used alongside thorough review and editing by the writer or a human editor familiar with academic writing standards.

Can These Tools Detect Plagiarism?

Many advanced AI grammar checkers come with an integrated plagiarism detection feature. These tools compare the submitted text against a vast database of published material to identify potential plagiarism. This feature is particularly useful for writers, educators, and students to ensure the originality of their work.

However, it’s important to note that the effectiveness of plagiarism detection can vary based on the tool’s database and algorithms. For critical academic or professional work, it might be advisable to use a dedicated plagiarism detection service alongside the grammar checker for a more thorough check.

What Should I Do if the AI Tool’s Suggestion Seems Incorrect?

If an AI tool’s suggestion appears incorrect or unsuitable, it’s important to trust your judgment and review the context of your writing. AI tools are not infallible and can sometimes misinterpret the intended meaning or style. In such cases, consider the following steps:

  • Review the sentence for context and clarity.
  • Check other reliable sources or grammar guides if you are unsure about a rule.
  • If possible, consult a human editor for a second opinion. Remember, AI tools are aids designed to assist, not dictate, your writing process.

Can AI Grammar Checkers Work in Languages Other Than English?

Many AI grammar checkers offer support for languages other than English, but the extent and effectiveness of this support can vary widely among tools. Some, like Ginger, are known for their multilingual capabilities, providing grammar checking in several languages. However, the accuracy and depth of checking in languages other than English might not always match the proficiency level of English checks.

It’s advisable to choose a tool that specifically mentions support for the language you need and to cross-check its effectiveness with native speakers or other resources
