🧸 What this is

Eighteen little 3D worlds for children learning English, about 2 to 6 years old. Click anything and hear its word, then a short, friendly conversation about it. There are games to find things and to say their names, and six science worlds with experiments to guess and watch.

They were made in Hong Kong for two brothers, Hank and Cooper, and are shared for every child learning English. Free, with no ads and no accounts.

• Nothing about your child leaves your device. What has been heard, found and said, and the settings, are kept in this browser only (its local storage). To wipe them, clear this site's data in the browser's settings.
• No cookies, no ads, no accounts, no tracking across sites.
• We count visits with Cloudflare Web Analytics, which uses no cookies and collects nothing personal: only things like which page was opened and how fast it loaded.
• The worlds never use the microphone or the camera, and the site tells the browser to refuse them.
