The Office Assistant provides interactive advice, help, and tips to help you learn as you work. It’s also completely customizable, so you can choose the Assistant character and the options that best suit the way you work. Even though it’s called the Office Assistant, you don’t need Microsoft Office on your computer for the Assistant to work in Microsoft Project. It’s just a name.
If you have a question about some aspect of Microsoft Project, you can type that question in your own words, and the Assistant will "answer" by showing you a short list of online Help topics that give you the information you need. From the thousands of topics that are in the online Help, the Assistant picks and displays the topics that are most relevant to your question.
