Grammarly is the most popular online grammar checker. It uses artificial intelligence (AI) and natural language processing to identify grammatical and spelling mistakes. Its algorithms can also detect punctuation, word choice, and stylistic errors and offer corrections or suggestions.
We use the paid version of the tool for all of the guest post content we produce for clients. However, it’s not the only online proofreading tool. There are some great Grammarly alternatives that are particularly valuable for non-native English speakers.

Now let’s take a look at each option in detail.
Writer is an AI powered writing assistant and has many similarities to Grammarly. You access the software through the online editor or use the Chrome extension. The tool identifies grammar and spelling errors in your content and provides corrections. It also suggests synonyms and phrasing that improve the clarity of your content.
You can also use Writer to create style guides for your content. The style guides are great if you’re managing a large team of writers. You can share a document with your brand voice, banned terms, etc. It ensures everyone uses the same writing style.
Finally, Writer has an inbuilt plagiarism checker. It’s a useful function that helps ensure your content is always unique. The plagiarism checker is only available on the Enterprise Plan.
- Word processor and editing tool
- Grammar and spell-checker
- Style guides
- Chrome extension. Also, Google Docs, and
- Features like Brand Voice checking are only available on the Enterprise Plan
You can use the Writer grammar check tool for free. It helps you catch typos and grammar mistakes, it also provides some suggestions on how to improve your content. The Starter Plan is $11 per month per person or $99 if you pay upfront for a year. It provides you with more insights than the free account. You can make inquiries for the Enterprise Plan, which is the best option for teams.
ProWritingAid is one of the best Grammarly alternatives. It has extensions for all the major browsers – Firefox, Chrome, Safari, etc. – and works with writing platforms like Google Docs, MS Office, Gmail, and WordPress.
ProWritingAid has a clean, easy-to-use interface. You can choose from three English language styles: general English, US English, and British English. Having this choice helps you ensure spelling is consistent for your target audience.
ProWritingAid performs 20 different tests on your text. Aside from spelling and grammar, it also checks sentence structure, length, transition, and choice of words. It then provides you with suggestions on how to improve your content.
Another neat feature of ProWritingAid is the ability to create a personal dictionary. You can add specific industry terms or the name of businesses, etc. to your dictionary.
- Provides suggestions on how to improve the readability, grammar, and spelling
- Extension for all the major browsers
- Integrations with all the common writing platforms
- Desktop app only available on the paid plans
ProWritingAid has a freemium plan. Its paid plans start at $20 per month. You can opt for the yearly subscription for $79, or purchase the lifetime subscription for $299. If you want to use the plagiarism checker, particularly useful for academic writing, you’ll need one of the PremiumPlus plans.
Ginger is available on Windows, iOS, and Android. It doesn’t work on Mac. There are also extensions for Chrome and Safari. This Grammarly alternative also integrates seamlessly with the WordPress CMS, which is great, but it doesn’t work with Google Docs, which is odd.
Ginger allows you to choose between two different language styles: American or British English. The grammar checker is good, but not as good as Grammarly.
You can use Ginger to translate your text into 40 languages, including French, Hindi, Arabic, and Russian. It’s a bit like Google Translate in this regard. The quality of the translations is ok but not as good as a translation by a native speaker.
- Checks and fixes spelling and grammar mistakes
- A personal trainer feature to improve your writing style
- Translation feature
- Text to speech feature
- Not as good as some of the other tools on the list
- No app for Mac
The Ginger has a freemium entry plan that allows you to use the basic features. The website doesn’t list the prices of its premium plans, but the annual subscription costs $12.48 per month if you pay upfront according to the information I found elsewhere online. The quarterly subscription costs $19.98 per month if paid in full. A monthly subscription is $29.96.
WhiteSmoke offers a lot of features for writers, bloggers, and people who guest post. The proofreading software checks for grammar and spelling mistakes and punctuation and style errors. Like Grammarly, White Smoke gives specific suggestions for other words or phrases you could use. It also has a useful thesaurus feature.
A subscription to WhiteSmoke includes access to a range of educational videos. These tutorials cover English language topics ranging from prepositions and adjectives to nouns and verb agreements.
The one downside? Some customers have complained that White Smoke’s user interface tends to lag.
- Style and punctuation checker
- Translate your content to 55 languages
- A thesaurus for finding alternative words
- Only offers premium plans
- Misses a lot of mistakes
White Smoke’s cheapest paid plan, billed at $59.95 per year or $5 per month. You can do plagiarism checks on the paid plan. Most other tools that charge extra for this feature. You also get access to 100 templates for documents such as cover letters, resumes, and reports.
5. Hemingway App
The Hemingway App is great for checking the readability of a piece of writing. It helps improve your writing skills. For example, it highlights lengthy and complex sentences, even if they don’t have grammatical or spelling mistakes. The web version also gives your work a readability score.
As a simple readability tool, the Hemingway App is great. The readability analysis helps you create content that non-native English speakers would find it easy to read. It also scores your writing, so you can rate your content.
Another feature of HemingWay Editor is that it will estimate the reading time of your piece. Based on my experience, this feature is reasonably accurate.
- Suggests ways to improve your writing and provides a readability score
- Catches complex and lengthy sentences as well as sentences in the passive voice
- The suggestions can make your content too simple
- Does not check your grammar
HemingWay comes in two versions: the online version, which is free but has limited features, and the desktop version, which costs $19.99. The desktop version is available for both Mac and Windows.
AutoCrit is a tool aimed at people writing books or novels. Aside from checking grammar and spelling, it gives you useful suggestions for improving dialogue, pacing, and word choice. Essentially, a style checker for writers.
AutoCrit uses “knowledge” from thousands of titles to determine good content. They consider things like repetitiveness, variations in sentence length, and even how many times characters “waved”, “exclaimed”, or, “said” something. It highlights literary cliches in your work, gives you alternative passages, and lets you see how your writing stacks up against bestsellers.
For all its strengths as a creative writing tool, it can’t identify the passive voice. Grammarly is still the gold standard. Still, it’s a nice tool for professional writers.
- Helps you write better, punchier copy
- Catches spelling and punctuation mistakes
- Compare your book against content in your niche
- Only available online
You can try AutoCrit for free. The online app has no text limit and you get access to an online editor tool that checks your content for adverbs, repetition, and readability. The paid plan is $30 a month. There’s also an annual plan priced at $297 a year. You get access to automated scoring, suggestions for improvements, vocabulary suggestions, and other features on the Pro Plan.
Academic writing has become something of a joke among writers. Academics seem to specialize in long, convoluted titles, and what many say is pretentious grammar and vocabulary.
Fortunately, Writefull delivers on its promise to improve any academic text. It uses language models built from millions of journal articles to help you write clear, grammatically correct content without sacrificing academic rigor. It even makes suggestions to improve readability. Writefull also has language-translation capabilities, which comes in handy when you’re citing articles in another language.
The software is available as a keyboard shortcut that works with most word-processing and email applications. Unfortunately, Writefull isn’t available on mobile, which limits its usefulness. It would’ve been nice to have a mobile version to help academics translate foreign words the moment they read or hear them.
- A useful writing app for academics
- Impressive language library
- Can use it with Word and Overleaf
- More suited to academic writing
- No extensions
Writefull has a free entry plan you can use to test the software. There is a premium plan for institutions and individuals. The individual plan starts at $15.37 a month, which drops to $5.46 on the annual plan. The institutional plan is significantly more expensive.
PaperRater is a simple proofreading tool. However, it is in need of an update. Overall, the website feels like it was designed about 10 years ago.
The way it works is simple. You upload your content to the website, and it will check your content for grammar and spelling errors in real-time. It will also catch things like incorrect punctuation.
The free version is tricky to use, especially as the plagiarism checker is not integrated into the proofreader feature. If you want to use both elements, you have to copy and paste the text twice. The free version doesn’t tell you which lines have been plagiarized, instead only indicating the percentage of the document that is unoriginal text.
- It has a spelling checker and does grammar checking in real-time
- Minimal features
- The website and software is not user-friendly
PaperRater is the cheapest paid service on this list, at $11.21 per month. There is also a free version, but its features are limited, and you can only use it to check texts with a length of up to five pages.
Jetpack is a WordPress plugin that offers a wide range of modules, from analytics to site protection. Only Jetpack 7.3 and older versions offer the proofreading module, which checks for misused words, grammar, style, and spelling. Corrections are color-coded: red indicates a misused word or spelling error, green highlights a grammatical mistake, and blue means that the tool has a stylistic suggestion.
Jetpack is easy to use. You simply download the extension and then enable the module via your Dashboard. You can choose what you’d like Jetpack to look for, including complex phrases, jargon, biased language, and double negatives.
Jetpack does not make any distinction between the different English language styles. Variations of American, British, and Canadian English are in its dictionary, but it will not tell you if you accidentally switch from one to another. It’s a great tool to use if you’re serious about making money blogging.
- Edit your blog posts in WordPress
- It’s free
- Basic functionality compared to many other grammar checking tools
Jetpack is free to use. However, it only works on WordPress versions of 7.3 or lower.
The main advantage of 1Checker is its flexibility. This grammar correction tool offers an online version, a version for Windows and Windows 8, and a version for Mac. It also has Word and Outlook plugins.
1Checker checks for spelling and grammatical errors and provides you with an explanation for each issue flagged. For example, it catches things like dangling modifiers or provides suggestions on sentence construction. If you don’t want to review each error independently, you can click “Apply All.”
1Checker is an excellent tool if you’re keen to improve your writing. All revisions are stored in the user center, meaning you can review the mistakes you made. Like WhiteSmoke, you also get access to templates for various documents. 1Checker also has a translation tool.
Beware of false alarms, though. Some users have reported 1Checker flagging words when they are correct.
- Support across multiple platforms
- Free to use
- The User Interface needs an update
- Lacks some of the advanced features of other tools
- Misses grammar mistakes
1Checker is free. It’s amazing how much they offer, considering you do not have to pay for the service.
OnlineCorrection is very basic. You can use the tool to check your writing for spelling and grammatical mistakes as well as stylistic errors. All you need to do is copy and paste your content into the space provided, and press submit. If you check the Autocorrect box, the tool will correct your errors automatically.
OnlineCorrection has five English language style options: American English, British English, Australian English, New Zealand English, and South African English. You can also check German, Polish, French, Spanish, Russian, and Italian texts for spelling and grammar issues.
Unfortunately, the user interface feels clunky. It is not hard to use, but it’s not intuitive either. Furthermore, the checks are not done in real-time. You have to submit your article, and then it reviews the content before making suggestions for fixes. All of this takes some time.
- Free to use
- Automatically corrects mistakes
- Limited functionality
- Ads on the website
For a free tool, OnlineCorrection is good. However, OnlineCorrection does not have the comprehensive functions you get with other tools.
12. Slick Write
Slick Write is a free web-based grammar checker and spelling checker. Unfortunately, it does not have an autocorrect feature, which means that making revisions can be very time-consuming if your text has a lot of errors.
You can also quickly look up more information about a word from several sources. Click on a word, and you can search for synonyms via “Associated Words,” its definition via “Dictionary,” and more detailed information via the “Wikipedia” and “Google” options. The
Slick Write also has a useful autosave feature. Don’t forget to uncheck this box if you’re using a shared computer, especially if your work is confidential.
- It’s a free tool
- Identify grammatical errors
- There are ads on the page
- Not as good as many other tools
Slick Write is free. The tool is user-friendly and has several useful features. However, it’s not as good as Grammarly or the other premium editing tools on this list.
Reverso is available online, as a browser extension, or as a downloadable desktop application for the Mac OS. The online version of Reverso is straightforward to use. Just copy and paste your text, and the program will check for grammatical and spelling errors. Be aware that there is a limit of 600 characters per check, so Reverso is only suitable for checking short passages of text.
One useful feature of Reverso is that it gives additional information if it detects errors in your text. It will provide you with the definition of a word, its synonyms, the correct conjugation of a verb, and even explain grammar rules if needed.
You can also translate your text into French, Spanish, Italian, or German. It has only one English language style option – British English – but you can also check for errors in French text.
- Check grammar and spelling in multiple languages
- It’s free to use
- Limited functionality
- There are ads on the site
Reverso is a free grammar tool.
Readable shows you how easy your content is to read. The tool uses a combination of the Lensear-Write formula, the Flesch Reading Ease algorithm, and the CEFR to ensure clear and concise copy.
You can use Readable in a variety of ways: copy and paste your content into the text box, import your documents, and even scan entire web pages. It’s web-based, so there’s no need to download anything and you can use it with different platforms. The advanced algorithm will help you identify run-on sentences and other grammatical issues.
However, it does come with its disadvantages. First, you cannot save multiple versions of your content. You need to copy-paste those versions into separate text or word processor documents. It also doesn’t have any file-sharing capabilities.
If you’re a blogger or copywriter who cares about simple sentences, the free version of Readable should be good enough. I don’t see any compelling reason to pay for it, given its limited capabilities.
- Works across all devices
- Lacks the functionality of grammar tools
- Can’t share files with other users
At just $4 per month, it’s a very useful tool for professional and amateur writers who want to create great content.
Sapling is an AI writing assistant developed for customer-facing teams, for example, customer support or sales. Sapling helps you write better emails, compose social media posts, and more on the fly.
Sapling uses artificial intelligence to catch and correct common spelling and grammar errors, ensuring your communication is always correct. The more you use Sapling, the more it learns about your writing style.
The free browser extension that works with Firefox, Chrome, and other browsers, can be used with common text-based tools like email and chat but isn’t ideal for long-form content like blog posts.
- The writing app is designed for multiple users/ teams
- Helps you catch spelling and grammatical errors
- You can’t use it for long-form content
Sapling has three plans. There’s a free plan you can use to try the tool. The Pro Plan is $25 a month for an individual, which is quite expensive for this niche. You can make an inquiry about the Enterprise Plan, which is best for teams. With the premium plans, you get access to additional features.
16. Sentence Checkup
Sentence Checkup is as simple as copy checkers come. There’s nothing to download or install, just a text box, a dropdown menu for the English dialect you’re writing in, and a “Checkup” button that analyzes your copy in seconds.
The sample text and copy in the site itself don’t exactly inspire confidence in the product (one glaring error: “Seems difficult, isn’t it?”), it detects run-on sentences and offers suggestions to improve sentence readability quite well. It also runs a check for spelling mistakes.
Unfortunately, there is no mobile or offline version, so you need at least a laptop and an internet connection to use it. If you just need a free sentence checker, a Sentence Checkup should be enough for most purposes.
- It’s free
- Limited features and functionality
Sentence checkup is a free online tool.
Best Grammarly Alternative
Overall, ProWritingAid is probably my favorite tool. It is the closest alternative in terms of features offered and functionality. You can use ProWritingAid for both short and long-form content, and the 25 different checks it performs on your text make it very thorough.
If you’re looking for a free tool, Reverso, Slick Write, and OnlineCorrection are great for checking shorter pieces of content. They’re not so useful for longer-form content and do have their limitations.
Each of these tools has pros and cons, and the one you choose will ultimately be down to your needs and budget. I hope this list has helped you to compare the different tools available and decide which one is right for you.
