for grown-ups
a small shelf of learning games, chosen by hand
Nerdi is a place for kids to play games that teach something real: science, technology, engineering, math, and learning to read. Every game here is made and checked by us before it goes on the shelf. Nobody else can upload or publish anything.
what your child will find
- 15 games ready to play today
- each game says what it teaches, the ages it suits, and how long one sitting takes
- games that run in the browser, with nothing to install
- a friendly voice that reads instructions aloud for children who can't read yet. It is generated by AI and recorded in advance
what your child won't find
- ads, or links that lead off the site
- chat, comments, or any way for strangers to make contact
- accounts for children, or anything to buy inside a game
free games and Nerdi Unlimited
One game in every subject is free for everyone, no sign-in needed. To play the rest, a grown-up signs in with Google or Apple and can then unlock every game with Nerdi Unlimited, a monthly or yearly plan you can cancel any time from your account.
reading aloud with the microphone
One game, Lantern Isle, can listen to your child read words aloud, if a grown-up turns it on in the game's grown-ups corner. It is off until you do. The game only listens while your child holds the read button, and a small speech model checks the word on your device: the sound is never recorded, stored or sent to us or anyone else. Without the microphone, children read by choosing the matching picture, and nothing else changes. No other game can use the microphone.
privacy
Children never sign in or give us anything. If a grown-up makes an account, we keep only their name and email from Google or Apple, plus their plan; Stripe handles payment and we never see card details. Favourites and the "jump back in" list are saved only in this browser, on this device. Clearing the browser's site data removes them.
We use Google Analytics to count visits to the site's pages, so we know which games people find and use. It doesn't run inside the games, Google's advertising features are switched off, and we never send it names, emails or anything a child types or says. There are no ads on Nerdi.
The full details are in our privacy policy and terms of service.
