Grammarly is the default choice for AI-powered writing assistance, and for good reason. Founded in 2009 by Alex Shevchenko and Max Lytvyn, it has grown to over 30 million daily active users, operates across every major platform — browser extensions for Chrome, Edge, Firefox, and Safari, desktop apps for Windows and macOS, mobile keyboards for iOS and Android, and integrations with Microsoft Office and Google Docs — and was valued at approximately $13 billion in 2021. Its features span grammar and spelling correction, tone detection, clarity suggestions, plagiarism detection (Premium), brand tone guidelines (Business), and generative AI through GrammarlyGO.
But “default” does not mean “best for everyone.” Grammarly Premium costs approximately $12 per month, and Business plans run about $15 per user per month. For some teams, that pricing is prohibitive. For others, the feature set does not align with their specific needs — perhaps they need deeper multilingual support, more aggressive stylistic editing, or tighter integration with a particular content management system. And for some writers, Grammarly’s suggestions feel too conservative, too generic, or too intrusive.
This article ranks the 10 best alternatives to Grammarly for business writing in 2026, evaluated against five criteria: accuracy of grammar and style correction, business-specific features, platform coverage and integrations, pricing and value, and AI writing assistance capabilities.
Evaluation Criteria
Before diving into the list, here is how we evaluated each tool:
- Accuracy: How reliably does the tool catch grammatical, spelling, and punctuation errors? How sophisticated are its style and clarity suggestions?
- Business Features: Does it offer team management, style guides, brand voice customization, analytics, or compliance tools?
- Platform Coverage: Which browsers, operating systems, and applications does it support? How seamless is the integration?
- Pricing: What does it cost for individual and team plans? Is there a free tier that is genuinely useful?
- AI Capabilities: Does the tool offer generative AI features — rewriting, summarization, composition — beyond basic correction?
1. ProWritingAid
Best for: Writers who want deep stylistic analysis and long-form editing
ProWritingAid is the closest competitor to Grammarly in terms of feature depth. It offers grammar and spell checking, but its real strength is in stylistic analysis. The tool generates detailed reports on readability, sentence structure, overused words, transitions, pacing, dialogue tags, and more — over 20 distinct writing reports in total.
For business writing, ProWritingAid’s value lies in its ability to improve not just correctness but quality. It catches passive voice, nominalization, vague language, and unnecessary complexity in ways that go beyond what Grammarly typically surfaces. The tool integrates with Chrome, Edge, Safari, Word, Google Docs, Scrivener, and most major writing platforms.
Pricing: A lifetime license is available for a one-time fee of approximately $399, making it dramatically cheaper over time than Grammarly’s subscription model. Monthly plans start at roughly $30, and annual plans are approximately $120. There is a limited free version.
Limitations: The interface is less polished than Grammarly’s. Real-time suggestions in browser extensions can be slower. Team and enterprise features are less developed.
2. Hemingway Editor
Best for: Teams that prioritize readability and conciseness
Hemingway Editor takes a fundamentally different approach from Grammarly. Rather than checking for grammar errors, it evaluates your writing for readability. The tool highlights sentences that are hard to read, very hard to read, or use passive voice. It flags adverbs, suggests simpler alternatives, and assigns a readability grade level to your text.
For business communication — particularly customer-facing content, support documentation, and executive summaries — readability is often more important than grammatical perfection. Hemingway forces brevity and clarity in a way that Grammarly’s more permissive approach does not.
Pricing: The desktop app is available for a one-time purchase of approximately $19.99. The web version offers a free tier. Hemingway has recently introduced an AI-powered version with generative capabilities at a subscription price.
Limitations: Hemingway does not check grammar or spelling. It is a complement to a grammar checker, not a replacement. No team management or enterprise features.
3. LanguageTool
Best for: Multilingual teams and organizations with privacy concerns
LanguageTool is an open-source grammar checker that supports over 30 languages — far more than Grammarly’s primary English focus with limited German, French, Spanish, and Portuguese support. For organizations that operate across multiple languages and need a single tool for all of them, LanguageTool is the strongest option.
The tool offers grammar, spelling, punctuation, and style checking. It provides a browser extension, a desktop app, and integrations with Google Docs, Microsoft Word, LibreOffice, and more. For privacy-sensitive organizations, LanguageTool offers a self-hosted server option where no text leaves the organization’s infrastructure.
Pricing: Free for basic checks (up to 10,000 characters per check). Premium plans start at approximately $4.99 per month for individuals and offer team plans at negotiable rates. Significantly cheaper than Grammarly at every tier.
Limitations: AI writing assistance features are less advanced than Grammarly’s GrammarlyGO. The style and tone suggestions in English are less nuanced.
4. QuillBot
Best for: Paraphrasing and rewriting at scale
QuillBot started as a paraphrasing tool and has evolved into a broader writing assistant. Its core feature remains paraphrasing — you input a sentence or paragraph, and QuillBot offers multiple rewritten versions in different modes: Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten. This makes it particularly useful for business writers who need to rephrase content for different audiences or contexts.
QuillBot also offers a grammar checker, summarizer, citation generator, and translator. The grammar checker is competent but not as comprehensive as Grammarly’s.
Pricing: Free for limited paraphrasing (125 words at a time, 3 modes). Premium plans start at approximately $9.95 per month, with annual plans reducing the cost to roughly $4.17 per month. No dedicated business tier.
Limitations: Not designed for team use. No brand voice or style guide features. The grammar checker is a secondary feature, not the primary product.
5. DeepL Write
Best for: Non-native English speakers who need natural-sounding rewrites
DeepL Write, from the company behind DeepL Translator, approaches writing assistance through the lens of translation expertise. The tool rewrites text to sound more natural, with particular strength in improving the fluency of text written by non-native speakers. It supports English, German, French, Spanish, Portuguese, and Italian.
For businesses with international teams where many employees write in English as a second language, DeepL Write addresses a problem that Grammarly only partially solves: making text not just correct, but idiomatically natural.
Pricing: Free for basic use within DeepL’s platform. DeepL Pro plans that include Write start at approximately $8.74 per month for individuals, with team and enterprise plans available at higher tiers.
Limitations: Limited to six languages. No browser extension as comprehensive as Grammarly’s. No plagiarism detection. Team features are less mature.
6. Wordtune
Best for: Quick sentence-level rewrites with AI-powered suggestions
Wordtune, developed by AI21 Labs, specializes in sentence-level rewriting. You highlight a sentence, and Wordtune offers several alternative versions — shorter, longer, more formal, more casual. It also provides a “Spices” feature that can expand on ideas, add counterarguments, or insert examples.
For business writers who need to quickly polish individual sentences in emails, proposals, or reports, Wordtune’s inline suggestions are fast and contextually relevant.
Pricing: Free for 10 rewrites per day. Premium plans start at approximately $9.99 per month. A Business plan is available with team features at approximately $14.99 per user per month.
Limitations: The tool is focused on rewriting, not comprehensive grammar checking. It does not offer the same breadth of error detection as Grammarly.
7. Writer.com
Best for: Enterprise content teams that need brand governance
Writer.com is the most direct competitor to Grammarly in the enterprise space. It offers grammar and style checking, but its differentiator is brand governance — the ability to enforce terminology, tone, and style rules across an entire organization. Writer.com includes a full-featured style guide, brand voice profiles, content compliance tools, and a proprietary LLM called Palmyra for generative writing.
For large organizations that need to enforce writing standards across hundreds or thousands of employees, Writer.com is purpose-built for the task.
Pricing: Writer.com focuses on enterprise pricing, which typically starts at higher per-user rates than Grammarly. Contact sales for quotes. Plans generally start around $18 per user per month for team plans.
Limitations: More expensive than Grammarly for smaller teams. The product is designed for content governance, which may be more than small teams need.
8. Ginger Software
Best for: Budget-conscious individuals who need basic grammar and translation
Ginger offers grammar and spell checking, sentence rephrasing, and a built-in translator supporting over 60 languages. It provides a browser extension, a desktop app, and a mobile keyboard. The translation feature makes it appealing for multilingual business communication.
Pricing: Free for basic grammar checking. Premium plans start at approximately $7.49 per month with annual billing. Significantly cheaper than Grammarly Premium.
Limitations: The quality of suggestions is generally considered less accurate than Grammarly’s. No team management or enterprise features. The product has not been updated as aggressively as competitors.
9. WhiteSmoke
Best for: Writers who want grammar checking with built-in translation
WhiteSmoke offers grammar, spelling, style, and punctuation checking along with a built-in translator and templates for common business documents (emails, letters, proposals). It integrates with web browsers, Microsoft Office, and Gmail.
Pricing: Plans start at approximately $6.66 per month for the web-only version and approximately $11.50 per month for the premium version with desktop integration. Annual billing reduces costs further.
Limitations: The interface feels dated compared to Grammarly. No AI writing generation features. Limited team and enterprise capabilities. Smaller user base means fewer updates and less community support.
10. Sapling
Best for: Customer-facing teams that need response suggestions and quality monitoring
Sapling is an AI writing assistant specifically designed for customer-facing teams — support, sales, and success. It offers autocomplete suggestions, grammar checking, and a library of pre-written snippets that agents can insert with keyboard shortcuts. The quality monitoring feature scores messages for professionalism, empathy, and accuracy.
For businesses where the primary use case is not long-form writing but high-volume, short-form customer communication, Sapling is more targeted than Grammarly.
Pricing: Free for basic autocomplete and grammar. Pro plans start at approximately $25 per month. Enterprise pricing is available on request.
Limitations: Not suitable for long-form or creative writing. The tool is narrowly focused on customer communication.

Conclusion
Grammarly remains the most complete all-in-one writing assistant for most use cases. Its combination of accuracy, platform coverage, enterprise features, and generative AI through GrammarlyGO is difficult to match with any single alternative. But “most complete” does not mean “best for your specific situation.”
If your team is multilingual, LanguageTool deserves serious consideration. If you need aggressive readability enforcement, Hemingway Editor does something Grammarly does not. If you are building an enterprise content governance program, Writer.com is the most direct alternative. If cost is the primary concern, ProWritingAid’s lifetime license or LanguageTool’s affordable premium tier offer substantial savings over Grammarly’s recurring subscription.
The best approach for many organizations is a combination: Grammarly or a primary alternative for everyday writing assistance, supplemented by a specialized tool for the specific gap that the primary choice does not fill. The market is mature enough that no single tool is universally superior, and the right choice depends on what your team actually writes, in which languages, and at what scale.
