Best Free Grammarly Alternatives in 2026: 5 Tools Compared

Grammarly Premium is a subscription, and for many writers it's one of the easier subscriptions to question. The free tier catches typos; the paid tier sells you clarity rewrites, tone help, and style polish.

So, is there a good free replacement? Honest answer: yes — the best free Grammarly alternatives now match or beat the free Grammarly tier, and one of them runs entirely offline. What no free tool fully replicates is Grammarly Premium's polished full-sentence rewriting.

There's also a question Grammarly's marketing doesn't dwell on: every cloud grammar checker reads everything you type into it. If that sentence made you pause, this list has options for you too. Our free Grammarly alternatives page tracks the full field with trust reports.

Quick picks

• If you want the best overall free checker → choose LanguageTool
• If you write in more than one language → choose LanguageTool (again)
• If privacy is non-negotiable → choose Harper (offline, open source)
• If you edit long-form drafts → choose ProWritingAid
• If you rewrite and paraphrase a lot → choose QuillBot
• If you only need basic typo-catching everywhere → Grammarly Free is still fine

Comparison table

LanguageTool — best overall free checker

LanguageTool is a freemium grammar checker built on an open-source core you can even self-host. The free tier checks grammar, spelling, and punctuation with generous limits; premium adds full-sentence rewrites and longer-text checks.

Where it shines:

• Supports more than 20 languages, with strong coverage of English, German, Spanish, French, and Dutch — the clear pick for multilingual writers.
• Browser extensions, desktop apps, and add-ons for Word, Google Docs, and LibreOffice.
• The open-source server can be self-hosted, so teams can run checks without sending text to anyone.
• Picks up regionalisms and false friends that English-only tools miss.

Where it falls short:

• Free checks have character limits per submission; long documents need splitting.
• Style suggestions are more conservative than Grammarly Premium's rewrites.

Choose it if: you want the closest free equivalent to Grammarly — or you write in any language besides English. See the head-to-head in Grammarly vs LanguageTool.

Grammarly Free — best if you stay put

Yes, the free tier of Grammarly itself belongs on this list — many people paying for Premium only ever needed Free. It's freemium, cloud-based, and English-only.

Where it shines:

• Correctness basics — grammar, spelling, punctuation — are solid and fast.
• The widest integration net in the category: browsers, desktop apps, mobile keyboards, and office suites.
• Tone detection gives a useful sanity check before you hit send.

What you lose versus Premium (the honest part):

• Clarity-focused sentence rewrites, word-choice upgrades, and fluency suggestions are locked.
• The plagiarism checker and advanced tone adjustments are Premium-only.
• Everything you type is processed in the cloud — that's the deal on both tiers.

Choose it if: basic error-catching across every app you use is all you actually need — cancel Premium before you switch tools.

ProWritingAid — best for long-form drafts

ProWritingAid is a freemium editor aimed at fiction and long-form writers. The free tier carries a word limit per check; its paid tier has historically been positioned as the budget-friendlier option in this space, with a one-time purchase edition among its offers — check the official site for current pricing.

Where it shines:

• Twenty-plus analytical reports: pacing, sentence-length variety, overused words, sticky sentences, dialogue tags.
• Reads like a writing coach, not just a typo net — it teaches patterns.
• Integrations for Word, Google Docs, browsers, and writing apps like Scrivener.

Where it falls short:

• The free word limit rules out checking a chapter in one pass.
• The interface is dense; casual users may find it like getting a physics lecture when they asked for spell-check.
• English only.

Choose it if: you're editing a manuscript or thesis and want depth over speed. The LanguageTool vs ProWritingAid breakdown covers which depth suits which writer.

Harper — best for privacy

Harper is an open source grammar checker that runs entirely on your device — no account, no cloud, no text leaving your machine. It's the answer to the question most checker users never ask.

Where it shines:

• Fully offline: your drafts, emails, and confidential documents are never uploaded anywhere.
• Extremely fast, since there's no network round-trip.
• Open source and auditable, with a browser extension and plugins for editors like Obsidian and code editors via language-server support.
• Free with no tiers, no limits, no upsell.

Where it falls short:

• English only.
• The rule set is lighter than LanguageTool's or Grammarly's — it catches real errors but offers fewer style suggestions.
• No mobile keyboard or office-suite integration yet.

Choose it if: you handle sensitive text — legal, medical, journalistic, or just private — and want checking without surveillance.

QuillBot — best for paraphrasing

QuillBot is a freemium writing tool best known for its paraphraser, with a competent grammar checker attached. The free tier limits paraphrasing modes and lengths; premium unlocks the rest.

Where it shines:

• Rewriting clunky sentences is its core skill — closest free analog to Grammarly Premium's rewrites.
• Grammar checking, a summarizer, and a translator live in one workspace.
• Browser extension and Word integration cover the common surfaces.

Where it falls short:

• Free paraphrasing limits are tight for heavy use.
• Grammar checking alone is weaker than LanguageTool's.
• Cloud-based processing, like Grammarly — same privacy trade-off.

Choose it if: your main struggle is rephrasing sentences rather than catching errors.

How to decide

Choose LanguageTool if you want one tool that does nearly everything free — and definitely if you write in multiple languages. Choose Harper if privacy beats feature count; it's the only pick where your text never leaves your device. Choose ProWritingAid if you're deep-editing long documents. Choose QuillBot if rewriting is the job. Stay on Grammarly Free if its integrations already cover your workflow and typo-catching is enough.

A note on privacy across the board: every cloud checker — Grammarly, LanguageTool's hosted service, ProWritingAid, QuillBot — processes your text on its servers. Vendors publish policies on retention and training use; read them before pasting anything confidential, or route around the issue with Harper or a self-hosted LanguageTool.

What you give up by leaving Grammarly

Grammarly Premium's full-sentence rewrites remain the smoothest in class, its tone adjustment is genuinely useful for workplace writing, and its integration coverage — especially mobile keyboards — is unmatched. Teams also lose the centralized style guide and analytics features.

If you only ever accepted the red-underline corrections, you'll miss nothing. If you leaned on "rewrite for clarity" daily, expect an adjustment period.

FAQ

Is LanguageTool really free?

The core checker is free and its engine is open source; you can even self-host it. Premium exists for longer checks and better rewrites, but the free tier is a complete grammar checker, not a demo.

What's the most private grammar checker?

Harper — it's open source and runs entirely offline, so nothing you write is transmitted. A self-hosted LanguageTool server is the next-best option for teams.

Do any free Grammarly alternatives support languages other than English?

LanguageTool is the standout, with quality checking in more than 20 languages. Grammarly, ProWritingAid, and Harper are English-only.

Can free tools replace Grammarly Premium completely?

For error-catching, yes. For polished sentence rewrites and tone coaching, only partially — QuillBot's free paraphraser gets closest, within limits.

Bottom line

LanguageTool for most writers, Harper for the privacy-minded, ProWritingAid for manuscripts — all genuinely free at the tiers described here. For the wider field, see our best writing assistants roundup.
