KIDDLE

Kiddle is a visual search engine designed for kids. It has the following features:

1) Safe search: sites appearing in Kiddle search results satisfy family friendly requirements, as we filter sites with explicit or deceptive content. 

2) Kids-oriented results: the boxes below illustrate how Kiddle returns results for each query (in the order shown):

Safe sites and pages written specifically for kids. Handpicked and checked by Kiddle editors. 
Typically, results 1-3.

Safe, trusted sites that are not written specifically for kids, but have content written in a simple way, easy for kids to understand. Handpicked and checked by Kiddle editors. 
Typically, results 4-7.

Safe, famous sites that are written for adults, providing expert content, but are harder for kids to understand. Filtered by Google safe search. 
Typically, results 8 onwards.

2) Big thumbnails: most Kiddle search results are illustrated with big thumbnails, which makes it easier to scan the results, differentiate between them, and click the most appropriate results to your query. Thumbnails serve as visual clues and are especially beneficial to kids as they don't read as fast as adults.

3) Large Arial font in Kiddle search results provides better readability for kids.

4) Privacy: we don't collect any personally identifiable information, and our logs are deleted every 24 hours.
