Free Spell Checker for Google Chrome is an extension that gives you an automated spelling checker for your web browser. 

When using the spell checker, the checker searches the entire text for spelling mistakes, and suggests any missing words, misspelled words, or words that don't exist in the dictionary. The suggestions are color-coded and can be removed, or you can replace them with your own suggestion. You can also adjust the suggestions to only appear in certain situations.

You can use this checker with many different languages. The dictionary contains English, Spanish, French, German, Italian, Portuguese, and Japanese words. This software is based on Google's cloud API and can be used with any Google product that uses the API.
