Looking for a Grammarly alternative? FlyMSG is the best Grammarly alternative for professionals who write for a living. It combines the FlyMSG AI Grammar Checker, FlyMSG Paragraph Rewrite, and the FlyMSG Auto Text Expander in one Chrome and Edge extension, checks grammar in 80+ languages, and works on any website with a text field. Grammarly fixes grammar errors and typos. FlyMSG fixes the typo, rewrites the paragraph, and types the next message for you.
If you pay $12 a month for Grammarly Pro (the price on Grammarly’s plans page as of September 23, 2026) and still retype the same emails every day, you have probably wondered whether there is a better option. There is.
A Grammarly Alternative Built for Busy Professionals Who Need More Than Red Underlines
FlyMSG is built around one promise: Type Less. Do More. Instead of only catching grammar errors, it helps knowledge workers and individual sellers save 20-30+ hours per month across email, LinkedIn, docs, and CRMs by acting as a full writing assistant for your workday.
Most AI tools for writing still stop at fixing typos or suggesting small tweaks. The best Grammarly alternatives do more. They rewrite, expand, and speed up your whole communication workflow. This page compares FlyMSG to Grammarly and the other tools people evaluate, then shows you how to pick the right fit. If you are still comparing options, our guide to free AI writing assistants covers the wider field.
FlyMSG vs Grammarly at a Glance
Here is how FlyMSG, the best Grammarly alternative, compares to Grammarly’s two self-serve plans. Grammarly details come from Grammarly’s plans page and language support page as of September 23, 2026. “Not listed” means the feature does not appear on Grammarly’s plans page.
| Feature | FlyMSG (best Grammarly alternative) | Grammarly Free | Grammarly Pro |
|---|---|---|---|
| Grammar and spelling checks | Yes, in 80+ languages | Yes, English plus 24 other languages | Yes, English plus 24 other languages |
| Paragraph rewriting | FlyMSG Paragraph Rewrite, on the free plan | 100 AI prompts a month | 2,000 AI prompts a month |
| Text expansion and snippets | FlyMSG Auto Text Expander (FlyCuts), on the free plan | Not included | Snippets included |
| LinkedIn comment and post generators | Yes | Not listed | Not listed |
| AI Sales Roleplay and sales prospecting training | Yes, on Business Pro and above | Not listed | Not listed |
| Plagiarism detection | No | Not included | Yes |
| Price | Free plan; Growth is $66 a year | $0 | $12 a month |
The short version: Grammarly Pro is the stronger pick if plagiarism detection matters most. FlyMSG is the stronger pick if you want grammar, rewriting, and text expansion on a free plan, plus tools built for LinkedIn and sales.
Why FlyMSG Is the Grammarly Alternative That Actually Speeds Up Your Work
FlyMSG is not another grammar checker with a different logo. It is an AI writing assistant that bundles grammar correction, full paragraph rewriting, and a text expansion engine into one browser extension, so you stop toggling between separate tools to send a polished email.
Here is what makes it different from Grammarly and the other editing tools on the market:
Core Benefits Compared to Grammarly
- Grammar and clarity in 80+ languages. The FlyMSG AI Grammar Checker corrects grammar, spelling, and punctuation while improving clarity and tone in the same pass, across 80+ languages. Grammarly lists English plus 24 other languages. LanguageTool lists more than 30 languages and dialects. QuillBot lists 6.
- Real rewriting on the free plan. FlyMSG Paragraph Rewrite transforms full paragraphs: shorten them, adjust the tone, sharpen clarity, or make text more persuasive. Grammarly Free caps AI prompts at 100 a month. QuillBot’s free plan paraphrases up to 125 words at a time.
- Text expansion without a paid plan. The FlyMSG Auto Text Expander lets you save the messages, replies, and templates you type every day as FlyCuts. Type a short code and the full email or LinkedIn message appears. Grammarly keeps snippets on its premium plan. FlyMSG includes advanced features like text expansion and rewriting on the free plan. The average knowledge worker loses 52% of the day to reading, writing, and refocusing, which is why time-saving tools matter.
- Works everywhere you write online. The FlyMSG extension runs on Chrome and Edge and works on any website with a text field: your email, LinkedIn, your CRM, your help desk, the web version of Google Docs and Microsoft Word, and anywhere else you type. No copy and paste into a separate editor.
- One tool instead of a stack. Many professionals pay for a grammar checker and a separate paraphrasing tool. For context, as of September 23, 2026: Grammarly Pro is $12 a month, QuillBot Premium is $8.33 a month billed annually, and ProWritingAid Premium is $120 a year with plagiarism checks sold separately. FlyMSG’s free and paid plans bundle grammar, rewriting, and text expansion together.
How This Grammarly Alternative Works in Your Daily Workflow
Switching from Grammarly does not have to be painful. You can install FlyMSG and use it on your next email in a few minutes. Here is the three-step process:
Step 1: Install FlyMSG on Chrome or Edge
Head to vengreso.com/get-flymsg/install for Chrome or vengreso.com/get-flymsg/install-edge for Edge. Click install, pin the extension to your toolbar, and log in or create a free FlyMSG account. Then open your email or LinkedIn and test the grammar checker on whatever you are writing right now.
Step 2: Configure Your AI Persona and FlyCuts
Set up your AI Persona by choosing your industry, niche, and preferred tone, such as professional, friendly, assertive, or casual. You configure it once, so your writing style stays consistent. It is not “learned” from your private data, which means consistent output without privacy concerns.
Next, save your most-used emails, LinkedIn messages, support replies, and internal notes as FlyCuts in the FlyMSG Auto Text Expander. This turns FlyMSG into a writing assistant that sounds like you from day one. If text expansion is new to you, start with what a text expander is and how it works.
Step 3: Write, Rewrite, and Correct Everywhere You Type
Now put it to work. Polish a LinkedIn message before publishing. Fix grammar in an email before you hit send. Rewrite a clunky paragraph in a proposal with FlyMSG Paragraph Rewrite to adjust tone, length, and clarity. Use FlyCuts to drop in a follow-up template in seconds instead of typing it from scratch.
The result: fewer rewrites, fewer spelling errors slipping through, faster responses, and more professional communication, all without bouncing between apps. The FlyMSG LinkedIn Comment Generator helps you write a thoughtful, personalized comment on a LinkedIn post in seconds, so engagement becomes a habit instead of a chore.
What Makes FlyMSG Different From Grammarly and Other Grammarly Alternatives
Many proofreading tools and Grammarly alternatives compete on a feature checklist: grammar accuracy here, style suggestions there, maybe a plagiarism checker bolted on. FlyMSG competes on outcomes. It is built around the full loop that knowledge workers and sellers need: learn, practice, engage, execute.
Key Differentiators
- Grammar, text expansion, and rewriting in one tool. The FlyMSG AI Grammar Checker, FlyMSG Auto Text Expander, and FlyMSG Paragraph Rewrite work together in one extension. If you are also weighing a TextExpander alternative, FlyMSG covers that job too.
- Designed for real work, not essays. FlyMSG focuses on the messages that drive revenue and relationships: prospecting emails, customer replies, project updates, internal notes, LinkedIn posts, and blog drafts. ProWritingAid is built around in-depth writing reports. FlyMSG is built for the professional who writes dozens of different things every single day.
- Proven productivity impact. FlyMSG has 25,000+ users across 12,000+ companies. As of August 31, 2026, the platform has tracked 3.4 billion+ characters typed, 284,000+ hours saved, and $9.06M+ in cost savings.
- Sales pros get a full enablement loop. Beyond grammar help, FlyMSG Business Pro adds FlyMSG AI Sales Roleplay and Coaching and FlyLearning, the FlyMSG sales prospecting training. Grammarly’s plans page lists neither. See how it compares in our roundup of AI sales roleplay tools.
- AI Persona configuration you control. You set your tone and industry once and get consistent output on every message. FlyMSG does not “learn” from your private data.
Proof That This Grammarly Alternative Works in the Real World
Picture a sales rep who replaces Grammarly with FlyMSG for daily outreach. Instead of toggling between a grammar checker, a paraphrasing tool, and a template manager, she polishes prospecting messages inline, inserts personalized follow-ups with FlyCuts, and rewrites cold email paragraphs for different audiences, all without leaving her inbox.
Enterprise teams like Juniper Networks and Proofpoint trust Vengreso’s methodology and tools for modern selling, which shows the approach scales beyond individual contributors. Teams can see the full program on the FlyMSG for sales teams page.
By August 31, 2026, FlyMSG users had fixed more than 1.3 million grammar and spelling issues through the platform. That number shows how much friction sits between professionals and polished communication.
The before and after is simple. Before FlyMSG: scattered tools and copy-paste workflows. After FlyMSG: one keyboard-driven workflow for writing, rewriting, and correcting.
Who Should Switch From Grammarly to FlyMSG?
Grammarly is a solid tool for what it does. Many professionals need writing tools that match the speed of their actual work. Here is who benefits most:
Ideal Users for This Grammarly Alternative
- Knowledge workers, customer support teams, and solopreneurs. You send dozens of emails, replies, proposals, and social posts a day. You need to catch grammar issues and sound polished, and you are tired of typing the same replies from scratch. FlyMSG lets you Type Less and Do More. If you are comparing the best writing apps or building better writing habits, FlyMSG belongs at the top of your list.
- Individual sellers (BDRs, SDRs, AEs). You want grammar polish plus fast personalization of outreach, LinkedIn comments, and first-touch emails in one workflow. FlyMSG’s text expansion for sales, rewrites, and AI sales roleplay give you accuracy and speed.
- Sales leaders and enablement teams. You care about consistent messaging across the team, faster onboarding for new reps, and skill development that goes beyond proofreading. Grammarly Pro includes one style guide and one brand tone, and Grammarly Enterprise includes unlimited. Neither plan lists sales prospecting training, coaching, or AI Sales Roleplay.
If you only need occasional spell-checks on short notes, Grammarly Free may be enough. FlyMSG shines when writing is central to hitting your goals and every typo, slow reply, or generic message adds up to lost deals and wasted hours.
AI-Powered Grammar and Spelling: How FlyMSG Catches Grammar Mistakes Without a Desktop App
FlyMSG is a browser extension, not a desktop app. There is no separate online editor to paste into. The AI-powered grammar checker sits in the text box you are already typing in and fixes grammatical errors, spelling errors, passive voice, complicated sentences, and weak sentence structure as you write, in 80+ languages. That covers your email, LinkedIn, your CRM, and the web version of Google Docs.
Three things separate it from a basic spelling checker:
- Sentence rewrites, not just corrections. When the fix is bigger than a comma, FlyMSG Paragraph Rewrite rewrites the sentence or the whole paragraph. You choose the tone. Your writing style stays yours because the AI Persona is configured once, by you, rather than guessed from your data.
- Multilingual support that goes beyond English. The FlyMSG AI Grammar Checker corrects 80+ languages, which matters if English is your second language, if you write outside your native language, or if your team writes in more than one language. It is included on the free plan.
- Consistency without a style guide project. Each person configures an AI Persona for tone and saves their best messages as FlyCuts, so every reply starts from approved wording.
Academic Writing, Long-Form Writing, and Plagiarism Checks
FlyMSG is built for the messages professionals send all day, not for a thesis. If you write long-form manuscripts or academic papers, a specialist long-form editor is a better fit. FlyMSG does not include a plagiarism checker. Grammarly Pro does, Grammarly Free does not, and ProWritingAid sells plagiarism checks separately. Use FlyMSG for the email, the LinkedIn post, the proposal, and the blog post, and pair it with a specialist tool when you need citations or originality reports.
FlyMSG vs Grammarly: Plan Comparison
Grammarly Pro is $12 a month as of September 23, 2026, and its Free plan caps AI prompts at 100 a month. Here is how FlyMSG’s plans stack up:
FlyMSG Free: The Best Free Grammarly Alternative for Everyday Use
The free version of FlyMSG includes the FlyMSG AI Grammar Checker, FlyMSG Paragraph Rewrite, and the FlyMSG Auto Text Expander, with a daily allowance on each. Grammarly Free gives you basic grammar and spelling suggestions and 100 AI prompts a month, with no snippets. If you only want a grammar checker, Grammarly Free is fine. If you want to rewrite and stop retyping, FlyMSG Free is the stronger starting point.
Typical free users: students, early-stage solopreneurs, and professionals testing a free Grammarly alternative before committing to a paid plan.
FlyMSG Growth: For Knowledge Workers Who Want to Type Less and Ship More
Growth is $66 a year and is built for people who use FlyMSG all day. You get grammar, rewriting, and template management in one subscription instead of paying for each separately.
Ideal use cases: consultants, marketers, operations leaders, and managers who live in email and docs all day. If you are exploring productivity tools to reclaim your schedule, Growth is where the return becomes obvious.
Save 20% on your first year. Use code 20PercentYr1 at checkout to get 20% off your first year on an annual paid plan. Growth drops from $66 to $52.80 for year one.
FlyMSG Business Pro and Business Pro Enterprise: For Sales Pros Replacing Grammarly With a Full Revenue Stack
FlyMSG Business Pro combines the AI Grammar Checker, text expansion, the LinkedIn tools, FlyMSG AI Sales Roleplay and Coaching, and FlyLearning sales prospecting training. None of that appears on Grammarly’s plans page.
FlyMSG Business Pro Enterprise and Enterprise+ serve sales teams of 10 or more and wrap the sales prospecting training curriculum, the PVC methodology, live training, and LinkedIn Profile Makeover for Sales Teams around the product. Sales leaders comparing Grammarly Enterprise to a modern alternative should weigh training, coaching, and engagement tools, not just proofreading. Grammarly’s paid plans give you a better style checker. FlyMSG’s paid plans give you a better team.
Other Grammarly Alternatives People Compare, and What Each Does Best
Buyers evaluating a Grammarly alternative usually shortlist the same handful of tools. Each is good at its own job. Here is what each vendor’s own site says as of September 23, 2026:
- QuillBot specializes in paraphrasing. Its free plan paraphrases up to 125 words at a time, it corrects grammar in 6 languages, and Premium is $8.33 a month billed annually.
- ProWritingAid offers in-depth writing reports. Premium is $120 a year, plagiarism checks are sold separately, and the free plan limits daily report runs.
- LanguageTool checks grammar in more than 30 languages and dialects.
- Wordtune offers context-based rewrite suggestions and lets you switch between casual and formal tones for different writing styles.
- Hemingway Editor focuses on making writing bold and clear, and offers a free online readability checker.
- Grammarly Pro itself includes a plagiarism checker, which FlyMSG does not.
None of them pairs grammar checking in 80+ languages with rewriting, a free text expander, and LinkedIn and sales tools in one extension. Prices in this category change often, so check each vendor’s own pricing page before you decide.
Free Grammarly Alternatives vs Paid Options: What a Free Plan Actually Gets You
Most tools on this page have a free version and a premium version, and the free plans differ more than the paid plans do. Grammarly Free gives you basic grammar and spelling suggestions with 100 AI prompts a month and no snippets. QuillBot’s free plan caps paraphrasing at 125 words at a time. ProWritingAid’s free plan limits daily report runs.
FlyMSG Free is different in kind, not degree. It includes grammar checking, rewriting, and text expansion on one free plan, with a daily allowance on each. If a free grammar checker is all you need, several free alternatives will do. If you want a free tool that also rewrites and stops you retyping, FlyMSG Free is the one to install first.
