How this ranking works

One method for every tool. We compared documented features and published prices; we did not run hands-on tests. Value carries the most weight.

ValueFeaturesEase of use

This list is for writers and students who want a free grammar checker and need to know where the free plan stops. We compared documented features and published prices for 10 checkers and ranked them by value first, then features, then ease of use. Value weighs what the free plan allows, such as word caps, daily rewrite limits and which checks are reserved for paid users, against the price of the cheapest upgrade. Prices are in USD as shown on each vendor's page on the check date; where a page showed only euros or zloty from our location, the price is marked pending.

The verdict

Grammarly is first because its free plan fixes spelling and grammar and reads tone across almost every app, and it only charges for rewrites, plagiarism checks and AI detection. LanguageTool is the best free choice for multilingual writers, and QuillBot is the best free study kit thanks to its paraphraser and summaries. ProWritingAid and Trinka are the best upgrade paths for novelists and academics. Wordtune, Hemingway, Ginger, Linguix and Sapling each do one thing well for free but are narrower.

    Best forStudents and general writers who want an accurate free checker that follows them across apps.

    Grammarly ranks first because its free plan does the basic job well and works almost everywhere people write. The plans page lists three things on Free: writing without spelling and grammar mistakes, seeing your writing tone, and generating text with 100 AI prompts. That is enough for most essays, emails and posts. The limits that push people to Pro are clear in the comparison table: adjusting tone, rewriting full sentences, fluency help, inclusive language, citation consistency, AI text detection and plagiarism checks are all marked unavailable on Free. Pro raises the AI prompt allowance to 2,000. Enterprise is now sold through Superhuman Go with data loss prevention and BYOK encryption. The vendor says it is trusted by over 40 million people and 50,000 organizations. From our location the plans page showed Pro only in euros, so the USD price is pending. We compared documented features and published prices; we did not run test documents.

    • ✓The free plan covers the core job of fixing spelling and grammar mistakes
    • ✓Free users also see a tone reading of their writing
    • ✓The vendor reports more than 40 million people and 50,000 organizations using it
    • ✕Full sentence rewrites are Pro only
    • ✕Plagiarism and AI detection are Pro only
    • ✕The plans page showed only euro prices from our location
    Free plan:

    AI prompts on Free:

    AI prompts on Pro:

    Bottom line: Grammarly is the safest free pick for most writers. Upgrade only if you need sentence rewrites or a plagiarism check.

    Best forWriters who work in more than one language or use LibreOffice, Apple Pages or Thunderbird.

    LanguageTool is the best free option for anyone who writes outside English. The premium page says it comes in 30+ languages and lists English, German, Spanish, French, Dutch and Brazilian Portuguese in its feature comparison. Its reach is also wider than most: there are add-ons for Chrome, Edge, Firefox and Opera, for Gmail, Apple Mail and Thunderbird, and plugins for Google Docs, Word, Apple Pages and LibreOffice, plus macOS and Windows apps. The free Basic plan covers core grammar, punctuation, style and spelling. Premium is what writers move to for enhanced grammar, punctuation and style checking, texts of up to 150,000 characters per text field, unlimited sentence paraphrasing powered by AI, and a style guide. Team plans exist for shared billing. From our location the page listed prices in PLN, so the USD price is pending. We compared documented features and published prices; we did not run test documents.

    • ✓Supports 30+ languages, far more than most rivals
    • ✓Works in LibreOffice and Apple Pages as well as Word and Google Docs

    Best forStudents who want grammar fixes plus paraphrasing and summaries in one free account.

    QuillBot suits students who need more than a grammar check. Its free plan lets you fix basic grammar errors, paraphrase up to 125 words in 2 modes, humanize up to 125 words with limited usage, generate basic summaries and use the AI detector on a limited basis. That covers a typical homework session. The limits are what push users to Premium: advanced grammar recommendations, full paraphrasing in unlimited modes, custom summaries, full AI detector access and plagiarism prevention all sit behind the paid plan. QuillBot notes that usage limits apply and may vary by surface, so the browser extension and web editor may behave differently. A Team plan adds a user dashboard, usage metrics, centralized billing and data controls. From our location the premium page showed euro prices only, so the USD price is pending. We compared documented features and published prices; we did not run test documents.

    • ✓Grammar, paraphrasing and summaries share one free account
    • ✓Free use needs only a sign-up
    • ✓A Team plan adds usage metrics and centralized billing
    • ✕Free grammar help covers basic errors only
    • ✕Paraphrasing and humanizing stop at 125 words on Free

    Bottom line: QuillBot is the best free all-in-one study tool here. Its grammar checker alone is more basic than Grammarly or LanguageTool.

    ProWritingAid

    8.5/10

    A grammar checker and style editor built for fiction and long-form writers, with manuscript reports and story planning tools.

    Free plan; Premium from $10 per month billed yearly ($120), $30 monthly or $399 one time

    Best forNovelists and long-form writers who want detailed style reports, not just error fixes.

    ProWritingAid is the strongest free choice for writers who want feedback on style as well as errors. Its pricing page shows a Free plan with grammar, spelling and punctuation checks, line editing reports that can run 2 times per day on 500 words of text, 10 rephrases per day, 3 Creative Nudges and 3 Sparks per day. It also offers 40+ document types and unlimited document storage. The 500-word cap is the limit that pushes most users to pay, because a novel chapter or thesis section is far longer. Premium costs $10 per month billed yearly at $120, $30 per month billed monthly, or $399 as a one-time payment, and Premium Pro adds 30 Chapter Critiques per day for $12 per month yearly. There is a 3-day money back guarantee rather than a long trial. The tools lean toward fiction, with Story Canvas and outline planning. We compared documented features and published prices; we did not run test documents.

    • ✓The free plan includes style reports, which most free checkers lack
    • ✓A lifetime option at $399 for writers who dislike subscriptions
    • ✓Unlimited document storage
    • ✕Free reports run only on 500 words at a time
    • ✕Monthly billing costs $30, three times the yearly rate
    • ✕The interface is built around long manuscripts, which is more than a student essay needs
    Free plan:
    Yes
    Free report limit:
    2 runs per report per day, 500 words
    Premium yearly:
    $120 ($10 per month)
    Lifetime:
    $399 one time

    Bottom line: ProWritingAid is the best upgrade path for serious writers. Its free plan is a useful taste, but the 500-word report cap is tight.

    Best forGraduate students and researchers who write papers to APA, AMA, IEEE or similar style guides.

    Trinka is the best pick for academic writers on a budget. Its pricing table shows a free Basic plan with 5,000 words of writing assistance per month, grammar checks in Lite Mode only, the paraphraser in Standard Mode only, 5 AI writing requests and 4 free credits per month. The FAQ says the Basic plan never expires but allows only limited usage. Premium costs $48 per year and unlocks full writing assistance, Power Mode grammar checks, style guide corrections for APA, AMA, ACS, AGU and IEEE, technical spell check, consistency checks and editable proofread files with tracked changes. Premium Plus at $75 per year adds yearly plagiarism and AI detection pages. File proofreading works on MS Word and LaTeX documents and is metered by credits. The 5,000-word monthly cap is what pushes thesis writers to pay. We compared documented features and published prices; we did not run test documents.

    • ✓The Basic plan never expires
    • ✓Premium is $48 per year, among the lowest paid prices here
    • ✓Built for academic writing, including LaTeX files
    • ✕Free grammar checks run in Lite Mode only
    • ✕Free writing assistance stops at 5,000 words per month
    • ✕Plagiarism reports use credits, which adds cost

    Premium:

    Bottom line: Trinka is the most useful checker for papers and theses. Its $48 yearly Premium is cheap, but the free tier is small.

    Best forWriters who want unlimited grammar checks plus a few AI rewrites each day.

    Wordtune is a rewriting tool first, but its free Basic plan is generous on grammar. The plans page lists unlimited spelling corrections and grammar checks at $0, along with 10 rewrites and AI suggestions per day and 3 AI summarizations per month. The daily rewrite cap is the limit that leads people to pay. Advanced costs $4.89 per month billed annually and raises the allowance to 30 rewrites per day and 15 summaries per month, while Unlimited costs $6.99 per month billed annually and removes the caps, adding vocabulary, clarity and fluency suggestions. Both paid plans start with a 3-day free trial, and business options add SAML SSO and centralized billing. The trade-off is depth: Wordtune does not document the style reports or multilingual checks that ProWritingAid and LanguageTool offer. We compared documented features and published prices; we did not run test documents.

    • ✓Grammar and spelling checks are unlimited on the free plan
    • ✓Paid plans start at $4.89 per month billed annually
    • ✓3-day free trial on paid plans
    • ✕Only 10 rewrites per day on Free
    • ✕Only 3 AI summaries per month on Free

    Best forWriters who want plainer, more readable prose rather than a full grammar audit.

    Hemingway Editor is the pick for writers whose problem is clarity rather than typos. The site offers free online tools, including a grammar checker, a paraphrasing tool, an AI proofreader and a readability checker, and its grammar checker page describes highlights for spelling errors, grammar mistakes and overly complex sentences. Editor Plus is where the depth lives: the Individual 5K plan costs $8.33 USD per month billed at $100 a year and includes 5,000 AI sentence rewrites per month, unlimited advanced grammar fixes, tone and length adjustment, a style guide, file import and export, and a target reading level. The 10K plan doubles the AI allowance for $12.50 per month billed annually. Hemingway states that neither it nor its AI providers train on your writing and that it does not store documents. There is a 2-week trial with no credit card. We compared documented features and published prices; we did not run test documents.

    • ✓Very simple highlight-based editing
    • ✓Clear privacy terms: documents are not stored or used to train AI
    • ✓A 2-week Editor Plus trial with no credit card
    • ✕Advanced grammar fixes and AI rewrites sit in Editor Plus

    Ginger is a long-running grammar checker that suits English learners. Its upgrade page says Premium fixes whole sentences in context, rephrases in one click, adjusts tone and translates into 40+ languages, working in the browser, on desktop and on mobile, with native integrations for Microsoft Office on Windows and for Google Docs. The FAQ states there is no free trial but that a free version with essential functionality is available, though the page does not list its exact limits. During the current 50% promotion, Premium costs $3.75 per month billed as one payment of $45.00 per year, or $6.5 per month billed monthly. Students and teachers can get 70% off after an eligibility check, and there is a 7-day money-back guarantee. Ginger Business supports teams and an API is sold for high volumes. We compared documented features and published prices; we did not run test documents.

    Best forPeople who type a lot of repeated text and want shortcuts alongside grammar checks.

    Linguix is a lighter alternative with one unusual extra. Its pricing page lists a Free plan at $0 forever with grammar and spelling checks, basic AI suggestions, limited paraphrasing, typing shortcuts and the browser extension. The typing shortcuts help anyone who sends the same replies often. The comparison table shows where the free plan stops: grammar and spelling are basic rather than advanced, AI suggestions and paraphrasing are limited, and style, clarity and tone suggestions are not included. Linguix Pro costs $11.67 per month billed at $140 annually and adds advanced grammar and style suggestions, more AI help, advanced rewriting, unlimited shortcuts and priority support. The vendor cites 450,000+ Chrome installs. At $140 a year, Pro costs more than Trinka, Ginger or Wordtune for a narrower feature set. We compared documented features and published prices; we did not run test documents.

    • ✓A free plan marked as forever
    • ✓Typing shortcuts are rare among grammar checkers
    • ✓Pro can be cancelled anytime
    • ✕Grammar and spelling checks are basic on Free
    • ✕Style, clarity and tone suggestions are Pro only

    Sapling started as a writing assistant for customer-facing teams and now pairs grammar help with an AI detector. Its pricing page shows a Free plan at $0 with basic writing assistance and AI detector checks of up to 2,000 characters per check, available in Chrome, Google Docs, Outlook and Word. Free also includes 20 snippets and works on free domains, while unlimited use on premium domains needs Pro. Pro costs $12 per month billed annually or $25 per month, adds advanced writing suggestions, autocomplete everywhere, rephrasing, unlimited snippets and AI detection up to 100,000 characters, and starts with a 1-month free trial that needs no credit card. Enterprise starts at 10 seats for $15 per seat per month with self-hosting options, and developers can buy usage-based APIs with a one-time $5 minimum. For students, the domain limit is the main reason to upgrade. We compared documented features and published prices; we did not run test documents.

    • ✓A free AI detector alongside grammar help
    • ✓A 1-month free trial of Pro with no credit card
    • ✓An API for developers with a $5 minimum

What to check before you pay

01

Find the limit that will stop you

Free plans differ in what they cap. ProWritingAid runs its line editing report on 500 words at a time, Trinka allows 5,000 words of writing assistance per month, Wordtune gives 10 rewrites per day, and QuillBot paraphrases up to 125 words. Grammarly and Wordtune do not cap basic grammar checks.

02

Check what is reserved for paid plans

Plagiarism checks are paid on Grammarly and QuillBot, and Trinka meters them with credits. Sentence rewrites are Pro only on Grammarly. Style, clarity and tone suggestions are Pro only on Linguix. If you need one of these every week, compare upgrade prices first.

03

Match the tool to the kind of writing

Students writing to APA, AMA or IEEE style should look at Trinka. Novelists get the most from ProWritingAid's reports. People writing in German, Spanish, French or Dutch should start with LanguageTool, and anyone fighting long sentences will like Hemingway's readability highlights.

04

Confirm it works where you write

LanguageTool has plugins for Google Docs, Word, Apple Pages and LibreOffice. Sapling works in Chrome, Google Docs, Outlook and Word. Ginger's Microsoft Office integration is Windows only. Check the integration list before you install.

05

Know the upgrade price

Verified upgrade prices start at $3.75 a month for Ginger Premium billed as $45 a year during a promotion, $4 a month for Trinka Premium at $48 a year, and $4.89 a month for Wordtune Advanced billed annually. ProWritingAid also sells a $399 one-time license. Grammarly, LanguageTool and QuillBot showed non-USD prices from our location, so their USD prices are pending.
