ImTranslator Spellchecker

It is helpful to check the spelling of the text to make sure that it’s error free. The built-in spellchecker checks spelling in English, French, German, Italian, Portuguese, Russian, Spanish, and Ukrainian languages.

Mark the "Auto spell" checkbox to run the spellchecker automatically when you click on the Translate button. The spellchecker starts checking spelling of the original text and provides spelling suggestions.
The auto spell-checking function is synchronized with the selected language pair.

It is highly advised to check spelling of your text before translation to get better translation results.
