spell-checking - Need Text Correction feature

Question

I need a text correction feature which can check for both the spelling and grammatical mistakes in the user written paragraph. I researched a bit but was able to find solutions which can check for the spell mistakes but not supporting the grammatical corrections / suggestions.

Do any one know such library / api which is suitable for both grammatical and spelling suggestions?
