The Internet has grown exponentially in the last fifteen years but search engines have not kept up—until now. Cuil searches more pages on the Web than anyone else—three times as many as Google and ten times as many as Microsoft.

Rather than rely on superficial popularity metrics, Cuil searches for and ranks pages based on their content and relevance. When we find a page with your keywords, we stay on that page and analyze the rest of its content, its concepts, their inter-relationships and the page’s coherency.

Then we offer you helpful choices and suggestions until you find the page you want and that you know is out there. We believe that analyzing the Web rather than our users is a more useful approach, so we don’t collect data about you and your habits, lest we are tempted to peek. With Cuil, your search history is always private.

Cuil is an old Irish word for knowledge. For knowledge, ask Cuil.

Features

Drilldown

After you perform a search, you may see a panel on the right-hand side that says “Explore By Category” with a list of subjects related to your search. If you roll-over a category, it will open and show refinements related to your search. If you click on one, Cuil will direct you to this additional information. By looking at these suggestions, you may discover search data, concepts, or related areas of interest that you hadn’t expected. This is particularly useful when you are researching a subject you don’t know much about and aren’t sure how to compose the “right” query to find the information you need.

Roll-over definition

When you pause on a subject suggested by “Explore By Category,” a definition of that term may appear. This gives you additional information to help you decide whether or not to click on that term and so save you some time.

Cuil helps you to search by offering you other choices and suggestions. Cuil will show you “Tabs” that suggest ways to clarify your search. For example, if you search for “Jaguar,” there are a number of things you could be searching for, like Jaguar cars, Jaguar cats, a football team called the Jaguars, etc. Just click on the tab that reflects your interest and Cuil will narrow your search appropriately.

Navigation suggestion

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. We let you look before you leap, because not everyone feels lucky.
