11 Best Grammarly Alternatives in 2026 (Free & Paid Tested)

The best Grammarly alternatives depend on what you write: LanguageTool for free multilingual grammar checking, ProWritingAid for long-form books and Scrivener manuscripts, QuillBot for paraphrasing, Hemingway App for cutting passive voice and dense sentences, ChatGPT for AI drafting, and Wordtune for sentence-level rephrasing. Each beats Grammarly on one specific axis. Below is the hands-on 15-error benchmark test and side-by-side breakdown of all eleven tools.

Still weighing whether to stay put? Try Grammarly free and see where its free plan holds up before you switch, or read our hands-on Grammarly review and Grammarly discount guide. Affiliate link. We may earn a commission at no extra cost to you.

It is also worth knowing what Grammarly has become. In late 2024 the company renamed its paid “Premium” plan to Grammarly Pro, folded the old standalone Business tier into Pro, and in 2025 rebranded its parent company to Superhuman after acquiring Coda and Superhuman Mail. If your reason for leaving is that Grammarly feels bloated or pushes paid upgrades too hard on the free tier, the focused tools below are the answer. See our Grammarly Free vs Pro breakdown if you want the exact feature split first.

1. Grammarly vs LanguageTool: Best Free & Multilingual Alternative

LanguageTool is the strongest free Grammarly alternative. It is open-source, supports more than 30 languages and regional dialects (including Spanish, German, French, Portuguese, and Dutch), and caught 12 of 15 errors in our benchmark test on its free tier, compared to 9 of 15 for Grammarly Free.

LanguageTool works as a browser extension, desktop app, Google Docs add-on, and integrates with LibreOffice, Microsoft Word, and Obsidian. While it lacks Grammarly’s tone detector and Grammarly Authorship keystroke tracking, its Premium plan costs roughly $5/month billed annually ($60/year), Less than half the price of Grammarly Pro ($144/year).

• Choose LanguageTool if: You want a generous free grammar checker, write in more than one language, or want a paid plan around $60/year.
• Choose Grammarly if: You write strictly in English and want one-click tone rewrites, plagiarism checking, and 2,000 monthly AI prompts.

2. Grammarly vs QuillBot: Best for Paraphrasing

QuillBot is the best Grammarly alternative when your main job is rewriting existing sentences rather than proofreading from scratch. It offers dedicated paraphrasing modes (Standard, Fluency, Formal, Academic, Shorten, Expand), a citation generator, and a fast browser extension.

Free-tier verdict: QuillBot’s free paraphraser lets you rewrite up to 125 words at a time immediately without creating an account. Grammarly’s free plan does not paraphrase full sentences at all; it blurs out full-sentence rewrites until you upgrade to Pro.

• Choose QuillBot if: Your main task is paraphrasing, summarising research, or reworking awkward phrasing as a student or non-native English writer.
• Choose Grammarly if: You want an always-on safety net across email, Slack, and Google Docs.

3. Grammarly vs Hemingway App: Best for Readability & Passive Voice

The Hemingway App focuses entirely on readability and sentence density: highlighting passive voice, weak adverbs, multisyllabic words, and sentences that are hard or very hard to read. Grammarly focuses on mechanical correctness and tone.

Hemingway’s web editor at hemingwayapp.com is 100% free with no word limit, while Hemingway Editor Plus adds AI sentence rewrites for a monthly subscription. You can also run the same deterministic passive voice and run-on checks right here in your browser using our free Passive Voice Checker and Run-On Sentence Checker.

• Choose Hemingway App if: Your drafts run long, passive, or academic and you want a visual grade-level check for free.
• Choose Grammarly if: You need spelling, punctuation, and grammar corrections alongside style pointers.

4. Grammarly vs ChatGPT: Best for AI-Assisted Drafting

ChatGPT and Grammarly solve opposite halves of the writing process. ChatGPT generates outlines, first drafts, and structural rewrites from a prompt; Grammarly checks the sentences you actually type inside your browser, email client, and word processor.

If you ask ChatGPT to “proofread this article,” it frequently rewrites your voice into generic AI prose full of words like delve, tapestry, and testament (test your draft with our Signs of AI Writing Checker to see this in action). Grammarly keeps your sentence structure intact and fixes specific mechanical and clarity errors inline.

• Choose ChatGPT if: You want to brainstorm angles, interrogate research notes, or restructure a rough draft.
• Choose Grammarly if: You want to polish your own prose without replacing your voice with synthetic LLM phrasing.

5. Grammarly vs Wordtune: Best for Rewriting Individual Sentences

Wordtune highlights any single sentence you select and offers 5 to 10 alternative ways to phrase it (more casual, more formal, shorter, or expanded). Grammarly Pro offers one suggested rewrite at a time; Wordtune gives you a menu of options so you can pick the rhythm that sounds like you.

• Choose Wordtune if: You know what you want to say in a sentence but want five variations to pick from.
• Choose Grammarly if: You want full-document proofreading, punctuation repair, and plagiarism checks.

6. Grammarly vs ProWritingAid: Best for Fiction & Long-Form Books

ProWritingAid is the best Grammarly alternative for novelists, memoirists, and long-form non-fiction authors. While Grammarly caps documents at 100,000 characters (roughly 15,000 words) and treats fiction dialogue like corporate email, ProWritingAid opens .scriv Scrivener projects directly and runs 25+ manuscript reports covering pacing, dialogue tags, sensory detail, clichés, and word echoes.

ProWritingAid is also cheaper over the long haul: its annual plan costs $120/year (vs $144/year for Grammarly Pro), and it sells a $399 one-time Lifetime license that pays for itself in under three years. Read our full ProWritingAid review and Grammarly comparison for the complete test data.

• Choose ProWritingAid if: You write books, edit in Scrivener or Word, or want a one-time Lifetime license instead of another SaaS subscription.
• Choose Grammarly if: You write short-form articles, business emails, and web copy across dozens of browser tabs.

7. Grammarly vs PerfectIt: Best for Style-Guide Consistency

PerfectIt is a Microsoft Word add-in built for professional copyeditors, legal teams, and technical writers. Instead of rewriting your prose, it scans long documents for internal consistency: hyphenation (e-mail vs email), capitalization of headings, acronym definitions, and compliance with Chicago Manual of Style, APA, or house style.

• Choose PerfectIt if: You are a book editor or technical writer enforcing a strict style sheet in Word.
• Choose Grammarly if: You want real-time grammar and clarity feedback as you draft.

8. Grammarly vs Ludwig: Best for Checking Native Phrasing in Context

Ludwig (ludwig.guru) is a linguistic search engine indexed against peer-reviewed journals, The New York Times, and published nonfiction. When you are unsure whether a preposition or idiom sounds natural in English, Ludwig shows real published sentences side by side so you can verify usage empirically.

• Choose Ludwig if: English is your second language or you want to verify how published authors phrase a specific construction.
• Choose Grammarly if: You want automated inline error detection.

9. Grammarly vs Writefull: Best for Academic & LaTeX Papers

Writefull is trained specifically on millions of peer-reviewed journal articles and integrates directly with Overleaf (LaTeX) and Microsoft Word. Where Grammarly often flags standard scientific passive voice ("samples were analyzed") as an error, Writefull understands academic register and includes an Abstract Generator and Academizer for research manuscripts.

• Choose Writefull if: You write STEM or social-science papers in Overleaf/LaTeX or Word.
• Choose Grammarly if: You write across general academic essays, emails, and business documents.

10. Grammarly vs Google Docs Built-In Checker

Google Docs’ native blue and red underlines catch basic typos and obvious subject-verb agreement slips, and Google Workspace plans now bundle Gemini for drafting. However, in our 15-error benchmark, Google Docs missed comma splices, dangling modifiers, US quotation punctuation errors, and close word echoes.

• Choose Google Docs alone if: You write casual internal notes and do not want browser extensions installed.
• Choose Grammarly if: Your writing goes to clients, editors, professors, or readers.

11. Grammarly vs Turnitin: Plagiarism & AI Detection Compared

Turnitin is institutional software licensed to universities; individual writers cannot buy a personal subscription. Grammarly Pro includes a web plagiarism detector and AI-text detector that scans ProQuest academic databases and billions of web pages, making it the closest pre-submission check students can run before uploading to Canvas or Blackboard. If you are worried about Turnitin flagging Grammarly edits as AI, read our guide on whether Grammarly counts as AI on Turnitin.

Does Grammarly Work in Spanish? (Best Spanish Alternatives)

No. Grammarly only checks English. It supports five English dialects (US, UK, Canadian, Australian, and Indian English), plus translation helpers in select beta workflows, but it will not proofread a document written in Spanish.

If you need a Spanish grammar checker (corrector gramatical), here are the two tools that work:

1. LanguageTool (Best overall for Spanish): Checks Spanish grammar, accent marks (tildes), gender/number agreement, and regional voseo/ustedeo conventions across Spain and Latin America.
2. BAWT Spanish Guides: If you write or edit in Spanish, see our Spanish guides to Las Mejores Aplicaciones de Escritura and Los Mejores Libros de Gramática.

Which Tool Should You Choose?

• Best 100% free alternative (and multilingual): LanguageTool
• Best for novelists, Scrivener users & Lifetime billing: ProWritingAid (Try ProWritingAid free)
• Best for cutting passive voice & long sentences free: Hemingway App + our Passive Voice Checker
• Best for paraphrasing & ESL sentence variety: QuillBot or Wordtune
• Best all-round assistant across browser, email & Docs: Grammarly Free or Pro (see our Grammarly review and Grammarly Free vs Pro pricing guide)
