18 Free Grammarly Alternatives to Help You Write Like a Pro

If you've ever stared at a blank screen, struggling to find the right words before a deadline, you know how stressful writing can be. Luckily, writing tools can help. Even for the most seasoned writers, these tools can make the process easier and improve the quality of the final product. But premium writing software like Grammarly can be expensive. If you want to boost your writing without paying for Grammarly, this article will explore Best AI Tools For Students, free Grammarly alternatives that can help you write confidently, and professionally.

One of the best free Grammarly alternatives is HyperWrite, an AI writing assistant that can help you achieve your writing goals. HyperWrite offers a suite of features that allow you to write, improve, and edit your work so you can produce high-quality content quickly, even if you’re under a tight deadline. 

What Does Grammarly Offer?

Person Working - Free Grammarly Alternatives

Grammarly is a widely used AI writing tool that catches and improves grammar, spelling, tone, clarity, and more. The free version of Grammarly is beneficial, but the premium version is where the software shines, offering advanced suggestions for improving all kinds of writing.

2. ProWritingAid: The Best Grammarly Alternative

ProWritingAid (PWA) is an excellent pick for authors looking for a Grammarly alternative. It does everything Grammarly does (and a whole lot more) while costing less and offering deeper analysis for long-form writing. Grammarly is great for catching basic mistakes, but ProWritingAid goes further. It helps you improve your:

  • Style
  • Tone
  • Pacing
  • Sentence variety
  • Echoes

Insights That Go Beyond Grammar

These matter when you’re writing a book or trying to polish up an article. Whether you're working on a fantasy novel, a blog post, or an academic paper, PWA gives you insights that go beyond grammar rules. And that's a big reason I recommend it. 

The free version gives you a solid taste of what the tool can do, though most of the advanced features are available only with the Premium or Premium Pro plans. 

Free Features

  • Browser extension
  • Spelling and grammar checker
  • Punctuation checker
  • Definitions and synonyms (double-click)
  • Limited style suggestions
  • Sentence structure tips
  • Access to 20+ writing reports (with limits)
  • Emailed writing stats

3. Writefull: The AI Writing Tool That Supports Academic Papers

Writefull is a perfect Grammarly alternative for students who need help with academic writing. You can use this tool to get feedback in Word or on your LaTeX code in Overleaf. You can also upload your text to their dashboard to check for:

  • Overall language quality
  • Correct any errors
  • Paraphrase accordingly

Diverse AI Tools for Text Generation and Analysis

They also offer other features where you can:

  • Enter your text and generate an abstract
  • Enter an informal sentence and get an academic rewrite
  • Check whether the text is generated using GPT-3, GPT-4, or ChatGPT

You can select the feature you require from the left sidebar and manage your account by clicking on the “Options” button at the top right corner. 

Pricing: The free subscription gets you all corrections and widget access for Word and Overleaf. 

4. GrammarLookup.com: A Simple Yet Effective Proofreader

GrammarLookup uses artificial intelligence to check for grammar, spelling, and style issues. Its more straightforward interface and a good database of grammar and punctuation checking abilities make it the best proofreader. The best thing about this tool is that you can use it online without registration. Simply copy and paste the text, click the Lookup button, and voila! 

You caught those typos (grammar, spelling, style issues, and more). Now go through each to correct them. (Don’t worry, you won’t lose formatting while returning text to your original editor, like MS Word.)

5. SentenceCheckup.com: Another Simple Proofreader

Sentence Checkup is another best alternative to Grammarly. It doesn’t require registration or Chrome extension installation. Simply head over to SentenceCheckup and paste the text, click the checkup button, and all possible grammar mistakes in your sentence will be highlighted. It can also check for sentence structure and fragments to fix mistakes in the context. Simply hover over each word, and you’ll have many options to correct the error.

Features

  • Language Selection: You can choose between British and American English, and it will adopt the style accordingly. The best thing is that it can detect excessive word usage to improve the readability of your content.
  • Simple interface: The clean and straightforward interface makes this grammar checker tool easy to use daily. It doesn’t ask to download a Chrome extension or sign up with an email; this saves you time.
  • Completely free: No trial, no text limit. It can be used multiple times.

6. LanguageTool: Great for Multiple Languages

LanguageTool is one of the best desktop-based grammar checker programs. It has a vast selection of tools and is available on Windows, Chrome, Safari, Firefox, and Mac. Not only can you use it as a proofreading tool, but you can even use it as a replacement for your phone’s autocorrect, to which LanguageTool might be superior. You can choose between:

  • American English
  • British English
  • Canadian English

Simple Interface for Effortless Corrections

The user interface is quite simple; the errors are highlighted, and hovering your mouse over the highlighted area gives you many options. It can also act as your English Tutor because it explains why any grammatical errors made are wrong, and there is also a text reader that can help you learn pronunciations.

Multi-Language Translation Support

LanguageTool also has a rephrase tool that looks for synonyms of words you’ve used in a sentence and changes them completely. This can make your sentences seem richer and well-thought-out. There is also a language-translation tool for over 40 languages, including:

  • French
  • German
  • Spanish
  • Urdu
  • Hindi
  • Arabic

7. Hemingway Editor: For Clear, Concise Writing

The Hemingway Editor stands apart on this list. Instead of picking out and correcting each grammatical or spelling error, the Hemingway app highlights things like:

  • Complicated sentences
  • Passive voice
  • Adverbs
  • Excessive wordiness 

Hemingway Editor is designed to make your writing more concise and clear through flow, word choice, and sentence structure. But it rarely gives you concrete suggestions on how to rephrase or restructure your writing. That's up to you. 

Free Website vs. Premium Desktop Versions

Unfortunately, it doesn't have a browser extension. The website is free to use, allowing you to copy and paste your text in. Or you can purchase the premium desktop version, which will enable you to import and export files. This makes things easier if you're checking long documents. (Like, say, a book manuscript.) 

Hemingway can certainly strengthen your writing, but you'll likely need one of the other tools on this list to locate the odd grammar errors and spelling mistakes because Hemingway does not. 

Features

  • Checks for adverbs
  • Checks for passive voice
  • Highlight complex and wordy sentences
  • Website version is free
  • Formatting options available in the free version
  • Super affordable premium version

The app is available for free on browsers, WordPress, and the Medium editor.

8. QuillBot: Free Paraphrasing Tool

With a user-friendly interface, QuillBot is another free Grammarly alternative to check:

  • Grammar
  • Punctuation
  • Spelling errors

Simply copy and paste the content into the tool, and it will automatically run checks. Errors are underlined, and you can see corrections on the right side of the screen. 

What makes QuillBot unique from other grammar checkers is that it not only checks grammar but also lets you format text and download the edited content as a Word document. You can:

  • Adjust font styles and sizes, bold, italicize
  • Change the alignment of the text
  • Set the background color of your choice

It also lets you paraphrase the text. QuillBot Grammar Checker supports English, German, Spanish, and French. 

9. Linguix: An AI-Powered Writing Tool

Linguix is an AI-powered writing tool that works similarly to Grammarly. It comes with a free plan for basic grammar fixes and a premium plan for advanced writing corrections, such as:

  • Redundancies
  • Confused words
  • Vocabulary improvements

AI-Powered Grammar and Vocabulary Enhancements

It uses AI to automatically scan the text instantly after you paste it into the designated box. Mistakes are underlined, and corrections appear as you click the word. It also gives synonym suggestions when you click on a specific word, making it yet another writing companion. The free version of Linguix, without sign-up, allows you to check basic grammar errors in short texts. 

For longer pieces, you can sign up and still use the free version. This free version also offers some additional features, including:

  • Sentence rephrasing 
  • Text quality score

You also get text statistics such as length and reading time.

Ensuring Brand Consistency with a Team Style Guide

The premium version of Linguix allows you to add your teams and specify a style guide. This stand-out feature lets brands ensure content consistency as the tool will give feedback to your team based on your style guide and brand voice. It also enables you to add AI shortcuts for repetitive text, such as:

  • Welcome text
  • Invoices
  • Follow-ups
  • Scheduling

Linguix offers a web-based platform and integration with browsers, content management, and communication platforms.

10. Reverso: Grammar Checker and Translator

Reverso is not just a grammar checker, but also a translation tool that translates to and from 26 languages, including:

  • Arabic
  • Korean
  • Dutch
  • Turkish
  • German
  • French

For grammar check, it supports:

  • English
  • French
  • Spanish
  • Italian

The free version only lets you check up to 450 characters and provides basic grammar fixes.

Multi-Platform Integration and Support

Reverso uses AI to automatically fix grammar errors once you paste or type the text. Like many other grammar checker tools, it also helps with sentence paraphrasing and provides synonyms for words. You can use its web-based platform or integrate it with:

  • Windows
  • Mac
  • MS Word

Its extension supports translation and dictionaries. 

11. Sapling AI: A Grammar Checker with Auto-Correct Features

This is one of the most accurate Grammarly alternatives that uses neural network-based language models for writing assistance. The free version catches most basic grammar errors, like:

  • Pronoun case errors
  • Punctuation errors
  • Spelling mistakes
  • Incorrect verbs

Enhancing Clarity and Word Choice

Sapling also gives suggestions for better alternatives for specific words and to cut unnecessary words, making your writing clear and flawless. You’ll have to upgrade to the premium plan for more advanced grammar checks, like:

  • Redundancies
  • Writing style
  • Fluency

The tool automatically underlines mistakes once you enter the text and gives correction suggestions on hover. You can check grammar in multiple languages, including:

  • English
  • Chinese
  • German
  • French
  • Italian
  • Portuguese
  • Japanese

Ideal for Marketers and Entrepreneurs

Sapling can seamlessly integrate with Chrome, Firefox, Edge, Opera, and Brave browsers. Its extension also works with most communication and content management tools, including:

  • Gmail
  • Outlook
  • MS Office
  • Slack
  • Shopify
  • Trello

This feature makes Sapling AI a decent choice for marketers and entrepreneurs.

12. PaperRater: A Grammar Checker for Students

PaperRater is a web-based grammar and plagiarism checker, specifically made for students and academic professionals. It’s free to use and doesn’t require sign-up, making things easier for you. The software checks various types of papers, including:

  • Essays
  • Theses
  • Business documents
  • Resumes
  • Articles
  • Short stories

Comprehensive Grammar and Style Checks

PaperRater checks spelling and grammar errors, style mistakes, word choices, and more. It highlights mistakes and gives correction options upon hover. When checking long texts and papers, it also gives them a grade based on various parameters, like:

  • Grammar
  • Word choice
  • Style
  • Spelling

PaperRaters also lets you send the analysis report to your teacher directly from its dashboard. The only downside is that the tool is not very accurate. It may miss some obvious grammar mistakes that you’ll have to fix with manual editing or proofreading. 

13. Virtual Writing Tutor: A Free ESL Writing Tool

The handy Virtual Writing Tutor is a completely free tool designed to help teachers, students, and those who are learning English as a second language. It's like PaperRater in that it has features designed with essay writing and grading in mind. Still, you can use it as a general proofreading tool by picking and choosing only the features that you need.

Unique Error Reporting Method

Like other proofreading tools, this website-based checker will underline each spelling error in red to tell you it's an error. But it won't suggest how to fix it. The other features, like the grammar checker, won't underline your mistakes. Instead, it generates a report under the text window to show you your mistakes.

Ideal for ESL Learners

While this can help you learn what you're doing wrong, it takes time to go back, locate the mistake, and fix it. Plus, the maximum number of words you can check is 3000. If English is your first language, this tool may not be the best fit for you. 

Nevertheless, in 2025, Virtual Writing Tutor added support for IELTS and TOEFL prep tools, boosting its value for ESL learners. 

Features

  • Check spelling and grammar
  • Check vocabulary and punctuation
  • Check topic sentence
  • Essay scoring
  • Proofreading gamification for new teachers
  • Lots of tools for ESL students
  • Text-to-speech feature
  • Completely free 

14. Microsoft Editor: A Free Tool for Microsoft Users

Microsoft Editor has always been one step ahead of the curve when it comes to spelling and grammar checkers. The red and blue lines underneath a word let you know that you made a mistake. While that feature is still available on Word, Microsoft 365 has improved the feature with Editor. 

It’s integrated with Microsoft 365 apps and can be used as a standalone tool that integrates with your browser. 

Advanced Refinements Beyond Grammar

Microsoft Editor is designed to improve the quality of writing by not only checking grammar and spelling but focusing on 8 Refinement categories. Before checking the refinement, you can select whether to base the suggestion on your writing style:

  • Casual
  • Professional
  • Formal

Refining Passive Voice and Stylistic Errors

Once the AI Editor understands your style, it will try and refine and improve the text based on these categories:

Editor can detect over 150 types of grammatical mistakes and areas of improvement, including:

  • Passive writing
  • Inconsistent pronouns
  • Oxford commas
  • Words out of context 

Interactive Corrections for Easy Editing

Microsoft Editor will highlight the word or words that need to be improved, and when you hover your mouse over them, it will show you the suggestion. You can then fix the mistake or accept the suggestion with a click of a mouse. One of the nice features of Editor is that it gives each piece of content an Editor score.

Writing Assessment and Scoring

The score is based on the writing style, spelling and grammar mistakes, and various refinement suggestions. The browser extension for Editor allows it to check everything that you write in your browser. This includes:

  • Emails
  • Social media updates
  • Blog posts
  • Chats

It has saved me on multiple occasions from making an embarrassing mistake before sending an email or publishing a post.

15. Wordtune: For Rewriting Your Sentences

Wordtune takes a different approach to grammar and spell checking, but the results are the same. The software has an AI algorithm designed for contextual understanding and then suggests alternative ways to improve it. The suggestions include:

  • Complete rewrite of the sentence
  • Changing some words to make it casual or formal
  • Reduce the length of a sentence by removing unnecessary or fluff words
  • Adding words to expand the sentence length

In addition to browser extensions for major browsers, Wordtunes also has an Add-in for Word, so you can get the suggestions and corrections when you’re not writing in your browser.

16. SlickWrite: Good for All Types of Writers

SlickWrite is a grammar and writing assistant perfect for all kinds of writers, such as novelists, students, bloggers, teachers, SEO professionals, etc. You can use the web version or extensions without logging in. You only need to upload a document or copy-paste it, and it checks instantly. SlickWrite can check the:

  • Spelling
  • Grammar
  • Flow
  • Structure of your writing
  • Suggest improvements to make

Some of its features include:

  • Customizable feedback.
  • Encrypted data for security and privacy.
  • You don’t need to sign up to use the Rhyming dictionary.

The only downsides of SlickWrite are that the fonts are of small size only, and the interface is not very intuitive. It is also too simple and won’t cater to advanced writing needs. It is perfect for an introductory text, though.

17. SentenceCheckup: A Simple Grammar Checker

SentenceCheckup is a good Grammarly alternative if you are looking for a simple grammar and writing assistant for a quick check. You don’t need to register or download an extension to use it: you only need to open the SentenceCheckup website and paste or type your text, then hit the checkup button. Some of the things it can check for include:

  • Grammar mistakes
  • Run-on sentences
  • Sentence structure
  • Sentence fragments
  • Readability

It can also detect and suggest alternatives for inappropriate words in the text. Some of its exciting features include:

  • You don’t need to register to use
  • Works with advanced algorithms to find minor errors and make checking and removing errors easier

On the downside, SentenceCheckup is not a good option for professionals who need advanced features to improve the quality of their writing. 

18. Ginger: A Grammar Checker with a Personal Touch

Ginger is an AI-powered writing assistant that uses patent-pending technology and Natural Language Processing to improve writing quality. Some of its interesting features include:

  • A sentence rephraser tool to enrich your text
  • A text reader tool to listen to your writing flow
  • Translator tool, dictionary, and a personal trainer to improve your writing skills
  • Contextual spelling correction

Two-Way Translation for Cross-Language Communication

Ginger works on the web, but you can also download the desktop and mobile apps. The translator tool is quite handy. If you are writing to someone who doesn’t understand your language, you can use it to translate before sending it. If they reply in their language, you can use it to switch the text back to yours. On the downside, Ginger doesn’t work on Google Docs.
