Here is how the site describes itself.
Welcome to www.HealthCare.gov, a website we designed to help you, your family, your business, your parents and grandparents, and your neighbors and friends get the information you need to make the best choices about your health care.
Using our Insurance Options Finder, you can, for the first time through a single tool, identify both the private and the public health coverage options available in your local community. Through the Health Finder tool, you can find tips to help improve your health and prevent disease. In the “Information for You” section, you can learn more about your rights as a consumer in the health insurance marketplace and upcoming changes that will benefit you.
