Ginger corrects spelling and grammar mistakes based on the context of your complete sentences by comparing each sentence to billions of similar sentences from the web.
Ginger is integrated with MS Office and most web browsers which ensures that your work is correct. It will scan a whole document for you. This programme is free.
There is an educational package which is not free (you pay a license fee per pupil per year).
I have not used this package but they say:
