A good LanguageTool alternative catches grammar and spelling mistakes, explains its suggestions and works where you write: in the browser, in documents and in email. Check language support, style and tone features, privacy terms and what the free version includes. This page lists ten options in no particular order, then covers choosing a checker you'll trust.
LanguageTool's own site describes an AI grammar checker that checks grammar, punctuation and spelling in over thirty languages, with a paraphrasing tool and a free version. One detail many users don't know: its GitHub repository describes LanguageTool as open-source proofreading software under the LGPL licence, which matters to people who care where their text goes.
Below are ten LanguageTool alternatives in no particular order, sorted alphabetically, from grammar checkers to style editors. Each description comes from the tool's own website, re-checked today. If you blog, my list of common blogging mistakes covers the slips a grammar checker won't catch.

What a good grammar checker does well
- Explains itself. You learn more when suggestions come with a reason.
- Works where you write. Browser, documents, email and phone.
- Handles your language and dialect. UK and US spelling, plus any other languages you use.
- Knows when to leave you alone. Too many suggestions get ignored.
- Respects your text. Clear privacy terms for what you paste in.
Privacy: the question to ask every LanguageTool alternative
Grammar checkers read everything you type, including client emails and confidential documents. Read each tool's privacy terms, check whether your text is stored or used to train models, and look for business plans with stricter controls if you handle sensitive work. Open-source options give you another route, as long as you're comfortable with the technical side.
Grammar checker, style editor or AI rewriter?
Grammar checkers fix mistakes. Style editors make writing clearer and tighter. AI rewriters suggest new wording altogether. Many tools now do a bit of all three, but most are strongest at one. Pick based on what your writing needs most.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Getting the most from any grammar checker
- Set your language and dialect first, such as UK English.
- Add names and industry words to the personal dictionary.
- Accept suggestions one by one rather than all at once.
- Read the final version aloud.
- Turn off suggestion types you always ignore.
Which LanguageTool alternative suits which writer
- Multilingual writers need broad language support.
- Academics often prefer academic-focused checkers.
- Authors may want detailed style reports.
- Customer-facing teams want checks inside their support tools.
Why smaller grammar tools can be worth a look
Smaller checkers often specialise: one is brilliant at academic English, another at plain-English style, another at French. That focus can beat a general tool for your particular writing. Before you commit, check how often the tool is updated and whether it works in the places you write most.
If you're writing more with AI as well, my piece on training AI to write in your voice pairs well with a good grammar checker.
Do you make a grammar, spelling or writing tool? Tool makers can ask to be considered for a featured place on this list.
My plain advice on replacing LanguageTool
Paste the same two paragraphs, one formal and one casual, into two checkers and compare the suggestions. Keep the one that catches real mistakes without fighting your voice, and check its privacy terms before you install it everywhere.
Frequently asked questions
What does LanguageTool do?
Its own site describes an AI grammar checker for grammar, punctuation and spelling in over thirty languages, with a free version.
Is LanguageTool open source?
Its GitHub repository describes it as open-source proofreading software under the LGPL licence.
Do grammar checkers support UK English?
Most let you choose UK or US English. Set it before you start so spelling suggestions match.
Are free grammar checkers good enough?
For everyday writing, often yes. Free versions usually limit style and advanced suggestions.
Is it safe to check confidential documents?
Read the tool's privacy terms first. Some offer business plans with stricter data controls.
What's the difference between a grammar checker and a style editor?
Grammar checkers fix errors; style editors make writing clearer, such as shortening sentences and cutting jargon.
Do grammar checkers work in Google Docs and Word?
Many offer extensions or add-ins for both. Check the tool's site for the apps you use, because support varies.
Can grammar checkers handle informal writing?
Some let you set a casual tone so they don't flag every contraction. If a tool keeps correcting your natural voice, you'll want to adjust its settings.
Will a checker catch every mistake?
No. They're good at common errors but can miss context, so it's still worth reading your work aloud before you send it.
Do I need more than one grammar tool?
Usually not. One good checker plus reading your work aloud catches most problems; a style editor helps if clarity is your weak spot.
