Here's what the search engine can do for you. You decide if it's better than Google.
Typing Suggestions
As you're typing in a keyword in the search field, a menu will appear with suggested topics related to the search. For instance, if you type in the word "class", a menu will appear to suggest classifieds, classical music, classmates, etc. Incidentally, you can turn this feature off if you don't like it.
Safe Search
Cuil will filter through your search and keep pornographic material from your search results. This is particularly useful if you have children who use the Internet. You can also disable this feature.
Explore by Category
Cuil gives you more options when you search. It will suggest categories related to your query, so you can narrow your search down to a particular focus. This is a good tool to have when you are researching a subject you don't know much about. If you type in "cake", Cuil will suggest cakes, cake albums, American desserts, etc.
Roll Over Categories
If you choose to select American Desserts in the Explore by Category table, Cuil will then narrow down the search even further. It will suggest pound cake, angel cake, gooey butter cake, etc. 
Definitions
When you are using the Explore by Category function and choose to roll over a topic, Cuil will provide a definition of the subject as you roll over it. That way, you'll know if the topic is what you're looking for.
Tabs
Once you've entered your search terms, Cuil will give you the option to clarify what you're searching for. Once you've typed in "cake", a series of tabs will appear under your search field, suggesting ways to narrow down your search. In this case, they suggest cake decorating, wedding cake, cake recipes. A "more" tab will appear. You can click on it and find more fields related to your search.
Navigation Suggestions
When you type a query, sometimes you'll see a search suggestion with an icon representing a website. Click on this link and you will go directly to that website.
Columns
You can choose to have the information displayed in two columns, or three columns.
