Lantern Family

Lantern gives each child one page of YouTube videos, with no search box and no autoplay. A parent writes a few sentences about each kid and sets a few dials, such as how scary, how loud and busy, or how pushy about buying things a video may be. A model watches every video, pictures and sound, before it can reach a child's page, and only what fits that child's settings gets through. It runs in a web browser on any phone, tablet or computer, so there is nothing to install. It was built by a parent.
