Proofreading tools for PowerPoint

There is a new AddIn available for Microsoft PowerPoint that automatically corrects common grammatical mistakes as well as misspellings of words, terms, phrases, proper nouns, etc. It is available on Proofreadingtools.com for only $15. It's perfect for anyone who can't afford to have a proofreader on staff.

Sounds good.

I know of another software that does similar things. Global Vision at www.globalvisioninc.com
