Cuil searches for and ranks pages based on their content and relevance. When it finds a page with your keywords, it stays on that page and analyzes its content, concepts, their inter-relationships, and the page's coherency. Then Cuil offers you helpful choices and suggestions until you find the page you want. Cuil believes that analyzing the Web rather than our users is a more useful approach, so no data is collected about you and your habits. With Cuil, your search history is always private.
