LanguageTool is an Open Source proofreading software for English, French, German, Polish, Russian, and more than 20 other languages. It finds many errors that a simple spell checker cannot detect.

LanguageTool is freely available under the LGPL 2.1 or later.

For more information, please see homepage at, this README, and CHANGES.


PHP-Spellchecker uses the HTTP API from LanguageTool. As such, you'll require to have a proper LanguageTools server installed in order to use this spellchecker. Follow instructions on the LanguageTools GitHub's repo.

Or you can use docker and start a container of the server exposing the endpoint on port 8011:

docker run --rm -d -p 8011:8010 silviof/docker-languagetool



With LanguageTool server available at http://localhost:8011


$spellchecker = new LanguageTool(new LanguageToolApiClient('http://localhost:8011'));

// LanguageTools expects language formatted with a dash `en-US`
$misspellings = $spellchecker->check('mispell', ['en-US'], ['from_example']);
foreach ($misspellings as $misspelling) {
    $misspelling->getWord(); // 'mispell'
    $misspelling->getLineNumber(); // '1'
    $misspelling->getOffset(); // '0'
    $misspelling->getSuggestions(); // ['misspell', ...]
    $misspelling->getContext(); // ['from_example']

Or if you want to check a file instead:

// spellchecking a file
$spellchecker = $spellchecker->check(new File('path/to/file.txt'), ['en_US'], ['from_file']);
foreach ($misspellings as $misspelling) {

Available dictionaries

You can check supported languages availability of your LanguageTools installation by running:


$spellchecker = new LanguageTool(new LanguageToolApiClient('http://localhost:8011'));

$spellchecker->getSupportedLanguages(); // ['en','en-US',...]
