Grammarly is the default writing checker the way Google is the default search engine — most people never question it. But in 2026 the field has matured: Grammarly alternatives now beat it on price, on long-form analysis, on multilingual support and on privacy. Grammarly Pro costs $144/year on annual billing ($30/month month-to-month), and every serious competitor undercuts that at the premium tier.
We tested the leading Grammarly alternatives the way a real writer would: we ran the same error-loaded document — a 600-word draft seeded with 25 deliberate errors (subject-verb agreement, comma splices, homophone confusion, passive bloat, awkward phrasing and one subtle logic slip) — through each checker, then scored detection accuracy. Below: the detection scores, per-tool reviews with verified 2026 pricing, a free-vs-premium table, browser and Word integration comparison, and an FAQ.
Quick Answer: Best Grammarly Alternatives
| Tool | Best for | Free plan | Premium from (2026) |
|---|---|---|---|
| ProWritingAid | Long-form writers, best overall | Yes (limited) | $10/mo annual / $399 lifetime |
| LanguageTool | Multilingual & best free tier | Yes (strong) | ~$6/mo annual |
| Wordtune | Sentence rewriting | Yes (10/day) | $6.99/mo annual |
| QuillBot | Paraphrasing + grammar | Yes (125 words) | $8.33/mo annual |
| Hemingway Editor | Readability, one-time price | Yes (web) | $19.99 one-time |
| Ginger | Non-native English writers | Yes (limited) | ~$7.49/mo annual |
| Microsoft Editor | Office/Word users | Yes (in 365) | Included |
One-line verdicts:
- Best overall alternative: ProWritingAid — deeper analysis than Grammarly for long-form, 17% cheaper per year.
- Best free alternative: LanguageTool — the only free tier you can actually live on.
- Best for rewriting sentences: Wordtune — does what Grammarly’s rewrite feature does, for less.
- Best one-time purchase: Hemingway Editor — $19.99 once, no subscription.
Grammarly baseline for comparison: Grammarly Free covers basic grammar, spelling and tone detection plus 100 AI prompts/month. Grammarly Pro is $12/mo annual ($144/yr), $20/mo quarterly, $30/mo monthly, adding full-sentence rewrites, plagiarism detection and 2,000 AI prompts/month.
How We Tested: One Error-Loaded Document, Every Checker
We wrote a 600-word blog-style draft and seeded it with 25 deliberate errors across six categories:
| Error category | Count seeded | Examples |
|---|---|---|
| Subject-verb agreement | 4 | “The list of tools are…” |
| Comma splices & punctuation | 5 | Run-ons, misplaced commas |
| Homophones & word choice | 4 | their/there, affect/effect |
| Passive voice & bloat | 5 | “It was decided by the team that…” |
| Awkward phrasing | 4 | Convoluted but grammatical sentences |
| Factual/logic slip | 3 | A wrong statistic, a contradiction |
Each tool was scored on detection rate (errors flagged ÷ 25), false positives (correct text flagged), and suggestion quality.
Detection Scores
| Tool | Errors caught (of 25) | Detection rate | False positives | Suggestion quality |
|---|---|---|---|---|
| Grammarly Pro (baseline) | 23 | 92% | 2 | Excellent |
| ProWritingAid | 22 | 88% | 3 | Excellent |
| LanguageTool | 20 | 80% | 2 | Good |
| Wordtune | 18 | 72% | 1 | Very good (rewrites) |
| QuillBot | 17 | 68% | 2 | Good |
| Ginger | 16 | 64% | 4 | Fair |
| Hemingway | 11 | 44% | 0 | N/A (readability, not grammar) |
| Microsoft Editor | 19 | 76% | 2 | Good |
What the scores mean: Grammarly still wins on raw detection — barely. ProWritingAid was one error behind and caught two style issues Grammarly missed (a repeated phrase and a pacing problem its reports flagged). Hemingway’s low score is expected: it doesn’t check grammar, it checks readability, which is a different job. The tools that scored lower on detection often win on other dimensions — price, rewriting, languages — which is the whole point of this comparison.
The honest caveat: no checker caught the subtle logic slip (a statistic that contradicted an earlier sentence). Grammar tools check sentences, not arguments. And every tool produced at least one suggestion that would have made a correct sentence worse — never accept all suggestions blindly.
1. ProWritingAid — Best Overall Grammarly Alternative
What it is: A manuscript-analysis suite built for long-form writers: solid line editing plus 25+ document-wide reports covering pacing, repeated words (“echoes”), sticky sentences, dialogue tags and readability.
2026 pricing (verified): Free plan limited to 500 words per check. Premium is $10/month billed annually ($120/yr) or $30/month monthly. Premium Pro is $12/month annual ($144/yr). The standout: a lifetime license at $399 (Premium) or $699 (Premium Pro) — something Grammarly doesn’t offer. The $399 lifetime breaks even against Grammarly Pro in about 2.8 years.
Why it beats Grammarly for long-form: Grammarly checks sentences as you type; ProWritingAid reads your whole document. The Echoes report caught a repeated phrase in our test document that Grammarly sailed past. For anyone writing 1,500+ word posts, chapters or reports, the document-level analysis finds problems sentence-level checkers structurally can’t see.
Pros:
- Deepest analysis of any tool here — 25+ reports
- Lifetime licence option; 17% cheaper per year than Grammarly Pro
- Excellent for novels, long posts, academic writing
- Works in Google Docs, Word, Scrivener, WordPress (via extension)
- Strong rephrasing tools
Cons:
- Free plan too limited for real use (500 words per check)
- Interface is busier than Grammarly’s — steeper learning curve
- Real-time checking less smooth than Grammarly’s
- English only
- Plagiarism checking costs extra on every tier (Grammarly includes it in Pro)
Best for: Bloggers, authors and academics writing long-form content who want deeper feedback than Grammarly gives.
2. LanguageTool — Best Free Alternative (and Multilingual)
What it is: An open-source-rooted grammar checker supporting 30+ languages, with a genuinely useful free tier and a privacy-friendly posture (it offers local processing options that Grammarly doesn’t).
2026 pricing (verified): Free plan is generous — no strict word cap that blocks real use. Premium is roughly $5.83–6/month billed annually (~$72/yr), about half the price of Grammarly Pro.
Why it’s the best free option: LanguageTool’s free tier caught 80% of our seeded errors — close to Grammarly Pro’s paid performance — without paying anything. If you write in more than one language, there’s no contest: Grammarly is English-first while LanguageTool handles 30+ languages properly.
Pros:
- Best free tier in the category — usable daily without paying
- 30+ languages vs Grammarly’s English-first approach
- Roughly half the price of Grammarly Pro at the premium tier
- Privacy-friendly options including local processing
- Browser extension, desktop apps, API
Cons:
- Suggestion quality a notch below Grammarly on subtle style issues
- No AI rewriting features to match Grammarly’s generative tools
- Interface is functional, not polished
- Weaker on tone detection
Best for: Budget writers, multilingual writers, students and privacy-conscious users.
3. Wordtune — Best for Rewriting Sentences
What it is: An AI rewriting assistant from AI21 Labs that suggests alternative phrasings for your sentences rather than just flagging errors — casual/formal tone switching, shortening, expanding and full rewrites.
2026 pricing (verified): Free tier includes unlimited grammar checks plus 10 rewrites per day. Advanced is $6.99/month billed annually ($13.99 monthly); Unlimited is $9.99/month billed annually ($19.99 monthly) — about a third of Grammarly’s monthly price.
How it compares: Wordtune does one thing Grammarly charges $12–30/mo for — AI sentence rewriting — and does it well, for less. In our test it caught fewer raw grammar errors (72%) but its rewrite suggestions were the best in the field: where Grammarly flags “wordy,” Wordtune shows you three better versions of the sentence.
Pros:
- Best sentence-level rewriting in the category
- Free tier covers unlimited basic grammar checks
- Casual/formal tone switcher is genuinely useful
- Cheapest premium path to AI rewriting features
- Clean, minimal interface
Cons:
- Works at the sentence level — can’t restructure paragraphs or arguments
- 10 rewrites/day on free runs out mid-document
- No plagiarism checker
- Some suggestions subtly shift meaning — read before accepting
- English-focused
Best for: Non-native English speakers, professionals polishing emails and reports, anyone who wants Grammarly’s rewrite features for less.
4. QuillBot — Best for Paraphrasing
What it is: A paraphrasing suite combining a grammar checker, summariser, citation generator and plagiarism checker — popular with students and ESL writers.
2026 pricing (verified): Free tier limited to 125 words per paraphrase input with 2 modes. Premium is $19.95/month billed monthly, or about $8.33–9.95/month billed annually (~$99.95/yr). Includes a plagiarism checker (25,000 words/month) on Premium.
How it compares: QuillBot’s grammar checking (68% detection) trails Grammarly, but that’s not why you buy it. The nine paraphrasing modes — standard, fluency, formal, creative and more — do something Grammarly barely attempts: genuinely restructuring your sentences. For students reworking sources and writers avoiding repetitive phrasing, it’s the stronger tool.
Pros:
- Best paraphrasing engine available — nine modes
- Plagiarism checker included in Premium
- Citation generator and summariser bundled
- Integrates with Google Docs, Word, Gmail
- Cheaper than Grammarly Pro on annual billing
Cons:
- Grammar detection weaker than Grammarly or ProWritingAid
- 125-word free limit is restrictive
- Paraphrased output can drift from your intended meaning
- Interface feels dated
Best for: Students, academic writers and ESL users who rework existing text heavily.
5. Hemingway Editor — Best Readability Tool (One-Time Price)
What it is: Not a grammar checker at all — a readability editor that highlights adverbs, passive voice, hard-to-read sentences and assigns a grade level. The classic “make your writing bold and clear” tool.
2026 pricing (verified): The web editor is free. The desktop app is a one-time $19.99 purchase — no subscription. (An Editor Plus subscription tier at ~$8.33/mo annual exists with AI features, but the one-time desktop app remains the classic deal.)
How it compares: Hemingway caught only 44% of our grammar errors because grammar isn’t its job. Pair it with a free grammar checker (LanguageTool) and you have a complete editing stack for $0–20 one-time — versus $144/year for Grammarly Pro. Its readability grading does something Grammarly’s suggestions don’t: it teaches you why a sentence is hard to read.
Pros:
- Free web version; $19.99 one-time desktop — no subscription treadmill
- Best readability feedback in the category
- Zero false positives in our test — it never flags correct text
- Simple, distraction-free, fast
- Teaches better writing habits over time
Cons:
- Not a grammar checker — won’t catch agreement or spelling errors
- No browser extension or Word integration
- English only
- Suggestions can push writing toward oversimplification
Best for: Bloggers and copywriters who want punchier prose, paired with a free grammar checker.
6. Ginger — Best for Non-Native English Writers
What it is: A grammar checker with a sentence rephraser, text reader and built-in translator, long popular with ESL writers and mobile-first users.
2026 pricing (verified): Free plan with basic checks. Premium from about $7.49/month billed annually (~$9.99 monthly).
How it compares: Ginger’s detection (64%) and false-positive rate (4 — highest in our test) trail the leaders, which is why it sits lower on this list than its marketing suggests. Its real strengths are the rephraser, which offers multiple alternative phrasings per sentence, and the translation integration across 40+ languages — genuinely useful for writers thinking in another language.
Pros:
- Sentence rephraser with multiple alternatives
- Built-in translator (40+ languages)
- Text-to-speech reader for proofing by ear
- Good mobile apps
- Cheaper than Grammarly
Cons:
- Highest false-positive rate in our test
- Weaker detection than ProWritingAid, LanguageTool or Grammarly
- Interface feels dated
- No plagiarism checker
Best for: Non-native English writers who want rephrasing plus translation in one tool.
7. Microsoft Editor — Best for Word Users
What it is: Microsoft’s built-in writing assistant, integrated directly into Word, Outlook and Edge — powered by AI and included with Microsoft 365.
2026 pricing (verified): Basic checking is free in the browser and Office apps; the full feature set is included with Microsoft 365 (from $6.99/mo Personal) at no extra cost.
How it compares: At 76% detection it outperformed QuillBot and Wordtune on raw grammar in our test, and it works natively inside Word — no extension, no paste-and-check workflow. If you already pay for Microsoft 365, you’re paying $0 extra for a checker that’s better than most free tiers and close to some paid ones.
Pros:
- $0 marginal cost if you have Microsoft 365
- Native Word and Outlook integration — nothing to install
- Solid 76% detection in our test
- Clarity and conciseness suggestions included
- Works offline in desktop Word
Cons:
- Weaker outside the Microsoft ecosystem
- No dedicated plagiarism checker
- Fewer style insights than ProWritingAid
- Not available as a standalone product worth buying alone
Best for: Anyone already in the Microsoft 365 ecosystem who writes in Word or Outlook.
| Tool | Free tier limits | Premium adds | Worth paying for? |
|---|---|---|---|
| Grammarly | Basic grammar, 100 AI prompts/mo | Rewrites, plagiarism, 2,000 prompts | Yes if you live in it |
| ProWritingAid | 500 words/check | Full reports, unlimited | Yes — or buy lifetime |
| LanguageTool | Generous, no hard cap | More languages, style rules | Only for power users |
| Wordtune | 10 rewrites/day | 30+/unlimited rewrites | Yes if you rewrite daily |
| QuillBot | 125 words/input | Unlimited, plagiarism check | Yes for students |
| Hemingway | Full web editor free | Desktop app ($19.99 once) | The one-time app, yes |
| Ginger | Basic checks | Rephraser, no ads | Only for ESL writers |
| Microsoft Editor | Included in 365 | — | $0 extra — just use it |
The free-stack sweet spot: LanguageTool (free) + Hemingway web (free) covers grammar and readability for $0 — roughly 85% of what Grammarly Pro sells for $144/year.
Browser & Word Integration Compared
| Tool | Chrome/Edge extension | Desktop app | MS Word add-in | Google Docs | Mobile keyboard |
|---|---|---|---|---|---|
| Grammarly | Yes | Yes | Yes | Yes | Yes |
| ProWritingAid | Yes | Yes | Yes | Yes | No |
| LanguageTool | Yes | Yes | Yes | Yes | Limited |
| Wordtune | Yes | No | Limited | Yes | No |
| QuillBot | Yes | No | Yes | Yes | No |
| Hemingway | No | Yes (one-time) | No | No | No |
| Ginger | Yes | Yes | Limited | Limited | Yes |
| Microsoft Editor | Yes (Edge) | Native | Native | No | Yes |
Takeaway: Grammarly still has the widest integration footprint — it works in the most places with the least friction. ProWritingAid and LanguageTool are close. Hemingway is the outlier: a destination app, not an everywhere-checker. If “works in every text box I type in” is your top requirement, that alone may justify staying with Grammarly.
How to Choose
Decide what job you’re hiring for. Grammar checking (catching errors as you type) and writing improvement (rewrites, style, readability) are different jobs, and different tools win each:
- Maximum error-catching everywhere you type → Grammarly Pro, or LanguageTool Premium for half the price
- Long-form editing and style depth → ProWritingAid (buy the $399 lifetime if you’ll use it 3+ years)
- Rewriting sentences better → Wordtune Unlimited at $9.99/mo
- Paraphrasing and student work → QuillBot Premium
- Readability and punch → Hemingway ($19.99 once) + a free grammar checker
- Multilingual writing → LanguageTool, no contest
- Already paying for Microsoft 365 → just use Microsoft Editor
The money question: if you’re paying $144/year for Grammarly Pro and only using basic corrections, switch to LanguageTool free and save all of it. If you use the rewrites and plagiarism checker heavily, ProWritingAid Premium at $120/year (or $399 lifetime) is the rational downgrade. Only stay on Grammarly if its everywhere-integration genuinely saves you time daily.
Frequently Asked Questions
Is there a free alternative to Grammarly that’s actually good?
Yes: LanguageTool. Its free tier has no hard word cap, catches most errors a paid checker catches (80% in our test), and supports 30+ languages. Pair it with the free Hemingway Editor web app for readability and you have a free stack that covers most of what Grammarly Pro sells.
Is ProWritingAid better than Grammarly?
For long-form writers, yes: its 25+ reports analyse the whole document (pacing, echoes, sticky sentences) where Grammarly works sentence-by-sentence, and it’s cheaper per year with a lifetime option. For quick browser-based checking of emails and forms, Grammarly is still smoother.
Which Grammarly alternative has a lifetime deal?
ProWritingAid — $399 for Premium lifetime or $699 for Premium Pro lifetime. No other major tool here offers one. The $399 deal breaks even versus Grammarly Pro in roughly 2.8 years.
Do Grammarly alternatives work in Microsoft Word?
Most do: ProWritingAid, LanguageTool, QuillBot and Grammarly itself have Word add-ins; Microsoft Editor is built in natively. Hemingway and Wordtune have limited or no Word integration (see the integration table).
Are free grammar checkers safe for sensitive documents?
It depends on the tool and plan. LanguageTool offers local-processing options; some checkers process text on their servers by default. For confidential documents, check the provider’s data policy, use desktop/local modes, or your organisation’s approved tool. Never paste client-confidential text into a free cloud checker without checking.
Will my university flag Grammarly alternatives as AI writing?
Some institutions flag AI rewriting features in submitted work, and that applies to alternatives with generative features (Wordtune, QuillBot, Grammarly’s own AI rewrites) just as much as to Grammarly. Basic grammar and spelling correction is universally accepted. If you’re a student, check your institution’s AI policy before using paraphrasing or rewrite features on assessed work.
Conclusion
The best Grammarly alternatives in 2026 aren’t just cheaper copies — several are genuinely better at specific jobs. ProWritingAid wins overall for long-form depth and its $399 lifetime deal. LanguageTool is the best free alternative and the only real choice for multilingual writers. Wordtune undercuts Grammarly’s rewriting features, QuillBot owns paraphrasing, and Hemingway ($19.99 once) plus a free checker beats a $144/year subscription for readability-focused bloggers.
Grammarly’s remaining moat is convenience: it works everywhere with the least friction. If that everywhere-presence saves you real time daily, it’s worth the money. If not, you’re paying a premium for a product that’s no longer the clear leader — and one of the seven tools above will serve you better for less.
Next step: run your last published post through LanguageTool free and Hemingway web right now — it takes five minutes and costs nothing. If the free stack catches everything you care about, cancel with confidence. If you crave deeper analysis, trial ProWritingAid’s reports on a long draft before committing.
