Created back in 2007, Ginger software is a reliable
It’s offered as a mobile app, a desktop version and a plug-in for web browsers— helping you with grammar correction wherever you want!
Like most proofreading software, Ginger helps you write and edit in real-time with its grammar, spell check and proofreading features. Ginger highlights grammatical suggestions in blue and provides alternative vocabulary for commonly used terminology. The software also has advanced natural language programming to function as a human editor.
Ginger software has a text reader that verbalises your text back to you, allowing you to listen to your flow, analyse the level of text engagement and eliminate passive voice.
However, that isn’t all.
Ginger can even translate your text into 60 different languages including Spanish, French and German for free! This is great for non-native speakers who struggle to write and spell in English.
The pricing differences between the two are minimal, and both churn out accurate edits. Ginger, however, is better suited to users writing in multiple languages. It even gives you English grammar lessons to sharpen your writing skills.
Ginger software will also provide sentence length and structure suggestions for lines that don’t read well. The tool instantly understands a sentence and rearranges the words, making it smoother and more readable.
- $0 per month (free Chrome extension)
- $29.96 per month (paid monthly)
- $12.48 per month (paid yearly)
- $9.99 per month (paid every two years)
Ginger also offers a 7-day, 100% money-back guarantee.
Pricing: $8.33 to $22.99 per month
Established in 2002, WhiteSmoke is a competitive proofreading tool that includes:
- Grammatical edits
- Punctuation edits
- A plagiarism checker
- A spell checker
- Over 100 templates
Templates inside of this proofreading software include a resume, thank you letters, cover letters, condolences, and more. It’s the perfect option for anyone looking to craft a quick document to send out immediately!
WhiteSmoke supports nearly 55 languages and provides suggestions through Statistical Machine Translation. This illustrates the way linguists on the WhiteSmoke team constantly work to improve translation quality and text.
It ensures your translations are contextually and grammatically sound.
This software supports most web browsers, including Google Chrome, Safari, and Firefox. It can also work with dedicated writing tools like MS Word, Google Docs, and MS Office.
WhiteSmoke will check 16 different kinds of sentence structure including fragments, run-on sentences, incorrect punctuation, and dangling modifiers.
Though not as fast or intuitive as the free version of Grammarly, WhiteSmoke offers some similar features, but at a lower price. You can use it to fix sentence structure issues too.
Unfortunately, the mobile app and desktop version don’t have very intuitive interfaces. For example, users must paste their content into WhiteSmoke. They can’t directly upload docs.
However, as a free plagiarism checker software, WhiteSmoke is still a powerful tool.
- WhiteSmoke Chrome Extension – $8.33 per month (paid yearly)
- WhiteSmoke Essential – $10 per month (paid yearly)
- WhiteSmoke Premium – $13.33 per month (paid yearly)
- WhiteSmoke Business – $22.99 per month (paid yearly)

Writer.com provides AI-driven copyediting, specifically for teams and anyone who creates content online. Larger businesses like Bill.com and Marriott International use it.
How does Writer.com differ from Grammarly?
Well, you can create and brand custom style guides with over 200 terms and share them with your team via a dedicated public URL. According to Writer.com, your style guide can align with other popular style guides like AP. Grammarly is currently rolling out a style guide in a business offering.
It also supports snippets, a type of like text expansion, or the popular tool Textexpander. Basically, create an abbreviation and Writer.com will expand it into something longer. It also offers versions for Chrome, Word, and Google Docs. No mobile app is available yet.
Writer.com struck me as accurate, fast, and polished. It provided accurate suggestions and also additional context to my grammar errors. I agreed with most of its suggestions and the proposed sentence rewrites were helpful. It's also cheaper than Grammarly and Grammarly business.
I briefly tested the plagiarism checker by pasting in articles from Become a Writer Today and from my old publications on Forbes. It picked up both snippets and provided the source link.
In short, Writer.com is a great Grammarly alternative for businesses, writers on a team and anyone worried about security.
5. Hemingway Editor
Pricing: Free or one-time payment of $19.99 for the desktop app
Hemingway Editor is a fast and efficient editing tool that largely focuses on improving readability.
While the other tools on this list point out grammar mistakes and spelling errors, the Hemingway app focuses solely on complex sentences.
Whether it’s lengthy sentences, run-on sentences, or the use of passive voice, Hemingway’s sentence rephraser will point out these errors. It’ll then break your writing into smaller and shorter sentences.
How does it do this?
It points out your “very hard to read” sentences (marked in red) and slowly progresses through a series of five colours (of declining difficulty levels) to help you simplify your text.
The Hemingway app also lets writers publish directly to WordPress and Medium to save time.
However, due to its lack of grammar, punctuation, and spell check features, I suggest you use it only as a secondary tool for polishing your sentences.
While Hemingway has more readability features than Grammarly, it can’t compete with Grammarly’s grammar checking features. If you plan to use the Hemingway app, you’ll probably have to use a secondary grammar checker tool for copyediting rather than relying on it to catch all of your grammatical mistakes.
While Hemingway’s sentence rephraser simplifies sentences, it can be problematic for a text covering complex ideas and details.
For instance, a scientific study about brain neurotransmitters will likely have a lot of red highlights because it’s difficult to read. This isn’t necessarily a reflection of poorly written work — it’s just a complicated topic!
On the upside, Hemingway maintains formatting when you copy and paste your text to it.
- Web app – Free
- Desktop app – One-time payment of $19.99 (I use the desktop app)
6. Virtual Writing Tutor
Virtual Writing Tutor is an online grammar checker that’ll help you correct:
- Spelling errors
- Grammatical mistakes
- Punctuation flaws
- Paraphrasing hiccups
- Vocabulary pitfalls
It’s useful for developing the writing skills of non-native speakers because of its English-as-a-second-language intelligence.
This free tool also offers proofreader training for novice teachers. It even lets teachers assign work to students to lessen their grading workload.
Virtual Writing Tutor can also gamify the grammatical correction process by highlighting grammar errors interactively. As well, it has a Target Structure Checker to help writers instantly improve the structure of their work.
Virtual Writing Tutor vs
While Virtual Writing Tutor offers some comparable features to Grammarly, the site creators suggest using a “two-pronged approach” for editing.
Run your text first through Virtual Writing Tutor and then through a free proofreading software like Grammarly to ensure that it is error-free.
While Grammarly is a better editing tool with a nicer interface, Virtual Writing Tutor is a completely free grammar tool.
If you’re a writer on a budget, this may be the ideal proofreading tool for you, even if it’s not as comprehensive as Grammarly.
- Visual Writing Tutor is a free tool
Pricing: One-time payment of €119 ($130)
Antidote is a lesser-known grammar checker, even though it has been around for years. In fact, the team at Antidote recently released version 10 of this tool.
While I spent a lot of time researching tools for this
It contains many comparable features to the other tools in this guide, but also has some unique characteristics. You can paste a document directly into Antidote or add their plugin to Word. It checks for language, typography and style errors. Antidote also supports a personal dictionary, meaning you can add frequently used words (e.g. a technical term or character name)
After buying an Antidote license, you can use a beta version of this
I’ve never run into issues checking my writing using grammar checkers that work online, but I can see how a tool like Antidote could help lawyers or those working on commercially sensitive materials.
Antidote also includes useful statistics and estimates. One feature that stood out is the billing time by rate and word. This suggests it’s a good tool for professional proofreaders and editors.
- Windows, Mac or Linux license – One-time payment of €119 ($130)
- Business pricing available upon request
A team from the University of Cambridge designed 1Checker as a tool for non-native English speakers.
The tool checks for a range of writing elements, including spelling, grammar, style, vocabulary and context-related errors using artificial intelligence and natural language processing technologies.
1Checker aims to catch the most common errors made by non-native English speakers that are often overlooked by other tools, such as:
- Incorrect use of articles
- Incorrect use of prepositions and pronouns
- Confused words
- Subject-verb agreement
- Incorrect tenses and adjective order
The platform is available as an online tool, as a Word plugin, as an Outlook plugin, or for download for Windows or Mac iOS.
At first glance, 1Checker has a simple design that feels a bit outdated when compared to similar tools. However, the analysis results are clear and easy to understand.
After you run the content through analysis, 1Checker provides an overview, which details the number of spelling, grammar, and other mistakes. The errors are clearly marked in blue and red, and the suggestions appear to the right with explanations and examples.
When compared to
Since 1Checker is designed to identify errors that non-native English speakers often make, this is one of the Grammarly alternatives that’s best suited for those who are still learning to write in English.
The 1Checker tool is completely free. You need to create an account to access it, which requires an email address or a Facebook account.
9. Slick Write
Slick Write is a free, cloud-based proofreading solution that allows users to check their documents for grammatical errors and stylistic issues. This tool checks for a number of writing elements, including:
- Grammatical errors
- Vocabulary variety
- Passive voice
- Readability and reading time
- Word, sentence, and paragraph length
- Sentence and structural flow
Slick Write is available online as a plugin for Chrome and Firefox, but you cannot download it to your computer for offline use.
Slick Write has a simple user interface. After submitting the text for analysis, you will see the errors and suggestions underlined in different colours, and when you click on the word or phrase, you see an explanation of the issue and suggestions for improvement.
Two unique features are the Statistics and Associator options. Statistics gives you a convenient overview of the writing, including stylistic elements such as readability and sentence length. The Associator provides the user with a list of associated words for a chosen word.
Slick Write vs
Though Slick Write offers fewer features than Grammarly, it is still a valuable free tool. With its stylistic review, Slick Write is ideal for those who have the basics of writing down but want to improve their writing style and readability.
The program is only available through the online site and as a plugin for Chrome and Firefox, which means it is not the best option for those who need offline or mobile access.
Slick Write is a free application that does not require you to create an account or log in.
10. Paper Rater
Pricing: Free to $14.95/month or $95.40/year
Powered by AI, Paper Rater provides online proofreading, grammar, and spelling checks without the need to download a program.
This tool focuses on providing opportunities for users to improve their writing through word choice, style, and vocabulary suggestions. The tool also offers a plagiarism checker, which is ideal for students who are submitting academic papers.
While the company promises real-time analysis in less than 10 seconds, the program takes a significant amount of time to analyse text, especially if you are using the plagiarism checker. The design is a bit outdated, and the interface is not the most user-friendly.
However, Paper Rater does offer unique features, such as word choice and style, to help elevate the user’s writing. Given the way that suggestions are phrased in the analysis section, this tool is designed with students in mind. It even offers a letter grade rating based on different elements of the writing.
Paper Rater vs
Many of the features of Paper Rater are limited in the Basic subscription, so users who want access to the full capabilities of the tool will need to upgrade to a paid subscription, which is currently more costly than Grammarly.
The tool is a great resource for students who need a free plagiarism and grammar check before submitting a paper. But it’s important to note that there is a five-page limit for the free subscription.
- Basic: Free (limited features).
- Premium: $95.40/year or $14.95/month.
11. Microsoft Word
Pricing: $5/month to $99.99/year
Well-known for its proofreading tool, Microsoft Word features intelligent technology that offers spelling error and grammar checks. It also offers stylistic writing suggestions in real-time as you create documents.
Microsoft Word is available for download or as part of Office 365, a cloud-based software solution that includes a variety of applications for creating, collaborating and presenting in the office.
Everyone is familiar with the red squiggly lines that identify your errors in a Word document. Microsoft has improved Word over the years, improving the usability and accuracy of its proofreading and grammar checker while making it simple to make changes to the document based on Word’s suggestions.
Microsoft Word vs
For those who want an effective word processing program with grammar and spell check included, Microsoft Word is a great tool. When testing the two, Microsoft Word found most of the grammar issues that Grammarly did, but not all.
Microsoft Word does not offer a free option, but it is affordable for households or offices with more than one user. If you really want to cover your bases, you can use Grammarly with Microsoft Word through its plugin.
- Office 365 Home: $99.99/year or $9.99/month (For up to 6 users).
- Office 365 Business Essentials: $5/month (web and mobile versions only).
12. Google Docs
You're probably already familiar with Google Docs, a web-based application where you can create, edit and store documents and spreadsheets online for free.
You can access the documents you create in Google Docs from any computer or device with an Internet connection and web browser. Based on machine translation, the grammar and spelling checker on Google Docs recognises errors as you type and offers helpful suggestions.
Google Docs feature a grammar and spelling checker that checks grammar automatically. It offers suggestions as you type, which you can accept or dismiss. The web-based application also offers a spelling and grammar check in the tools menu. Google Docs takes a unique approach to grammar in that it translates phrases from improper English to proper English.
Google Docs vs
Overall, Google Docs does not recognise as many errors or offer as many suggestions as Grammarly does. While it may address an errant comma, it may not detect improper word choice or subject-verb agreement when the subject is a proper noun.
However, the technology may continue to improve over time as Google makes adjustments. For now, it is one of the free Grammarly alternatives available.
Google Docs is free for personal use. All you have to do to get started is to create an account. If you use Gmail as your email provider, then you already have access to this tool.
Best known for its translation capabilities, Reverso is a web-based tool that also features a spelling and grammar checker.
It immediately checks for improper words and punctuation once you copy and paste your content into the tool. Reverso is actually powered by Ginger Software, mentioned earlier in this article.
Reverso is a tool with a user-friendly interface that catches basic grammar issues such as misspellings and punctuation issues. Then, it fixes them for you. The tool only allows you to check 600 characters at a time, which limits the type of content that you can put through the checker.
Reverso is effective in spotting basic grammar errors and translating content. Since it limits the amount of content that you can put through the checker, it may not be ideal for everyone.
However, even with its 600-character limit, it can work well for users who need to check shorter types of content, such as emails or social media posts. Though it does not have all the features that Grammarly offers, it works for those who want to quickly check short documents for basic errors.
Reverso is absolutely free – all you have to do is sign up for an account.
SentenceCheckup is a free online “sentence checker” that helps users identify run-on sentences and fragments.
This tool also helps correct grammatical errors and improve stylistic choices. SentenceCheckup is available through the online platform with no downloading necessary.
SentenceCheckup has a simple design that makes checking your text easy. All you need to do is copy and paste it into the text box and click the Checkup button. You can review the text in both American and British English.
The tool mostly focuses on improving sentence structure and readability while detecting run-on sentences and sentence fragments. It works quickly, providing you with an analysis in just a few seconds.
SentenceCheckup is ideal for those who want to improve their sentence structure and improve readability. Though it doesn’t offer all of the robust features that
SentenceCheckup is free without the need to create an account.
Pricing: Free to $4.92/month or $59/year

LanguageTool is easy to use with a simple user interface. All you have to do to utilise the tool’s features is copy and paste your content into the online text box and click on the Check Text button.
If you use the Chrome plugin, LanguageTool will check your grammar and spelling as you type, identifying errors and suggesting changes.
While LanguageTool detects basic grammar and spelling errors in English, it is also ideal for those who want to check their grammar and spelling in other languages. The free subscription is somewhat limited, as it only allows you to check 20,000 characters at a time and doesn’t detect as many errors as the premium subscription.
- Free: Limited to 20,000 characters per check and doesn’t include a plugin for Microsoft Word.
- Premium: $4.92/month or $59/year – includes detection of more than 2,500 additional errors.
Pricing: $18.95 per month
