KidRex is a kid friendly front-end for Google searches that uses Google’s SafeSearch technology to filter out child-inappropriate content. It’s a hassle-free tool for masking the underbelly of the internet from young searchers. KidRex isn’t as robust a solution as setting up a completely stand-alone browser with a white list like KidZui or using OpenDNS as a parental filter, but it is effective and more than adequate for preventing childhood curiosity from exposing kids to inappropriate content. Basic keyword queries that would lead a kid to wonder exactly why that girl has so many boyfriends are blocked, and the user is redirected to search again. If your eight year old nephew a robust vocabulary, however, KidRex won’t be much of a challenge. Search for curvaceous and you—and Junior—will find out that there is an entire magazine devoted to the implications of the word. In any case, if you’d like to be able to help a young-in research for a school report about cougars without having a conversation about the birds, the bees, and the economy of southern California, KidRex will provide more than adequate filtering.
