Daddy Instructions, a real Tandem book cover

Books you'll never find in the library.

How AI actually works, explained for a five-year-old. An official instruction manual for Daddy. Tandem makes the books that don't exist yet.

Built by scientists (who are parents).

Tandem is made by doctors and child psychologists raising kids of their own. Every book is designed to spark a conversation, not just fill time. Developed in partnership with Alder Hey, Moorfields and Nesta.

Questions parents actually ask.

Nothing sneaky. The free library is yours forever. If you want to keep creating, pay as you go for the book types you love, or subscribe. Whichever suits.

Safety is our number one priority. Tandem was designed by doctors and child psychologists, every book passes multiple safety guardrails before your child ever sees it, and it's been tested extensively with real families. More than 3 million words have already been created in Tandem.

Built for children aged 3 to 6, and made to be read together. But we do find lots of older and younger kids love it too. Every book is generated to be at just the right reading level for your child.

Any time, in a couple of taps. No phone calls, no hoops. And the free library stays yours.
