There is no Ask.com for kids website. The former Ask for Kids website was owned by Ask.com and was designed for ease of use by children who were not adept at typing questions on a computer.
In its terms of service, Ask.com states its current site and services are not intended for children under 13 years of age. Children under 13 may not create user profiles or join the Ask community.
As of August 2015, SafeSearchKids.com provides a Google search window with the Safe Search settings for kids. Other children's search websites as of August 2015 include KidRex, SearchyPants, Mymunka and Fact Monster.
