These checkers run in your browser with open-source dictionaries. They check spelling only, and your text never leaves your device.

How language support works

Every checker uses the same engine with a dictionary and rule set for that language. Support is deepest for widely used languages like English, German, French, Spanish, Portuguese, Dutch and Polish, which have thousands of grammar rules. For some languages, such as Chinese, Japanese, Khmer and Tamil, coverage focuses mainly on spelling and the most common errors.

You can also switch language at any time from the language menu inside any checker, or choose Auto-detect and let SpellMistake recognize the language for you.

Not sure which language?

Paste your text into the main checker, choose Auto-detect and SpellMistake will recognize the language.
