Your own AI tutor

Sign in to Claude, and Pip starts answering questions

Every book runs on this website for everyone, with no account. Only the AI features need Claude: open the AI version of a book while signed in to Claude, and Pip answers questions using your own Claude account.

  1. Open any book above. It works straight away on this website: read, watch the animations, practise, and tick off sections.
  2. For Pip, choose "With Pip, the AI tutor" under the book. This opens the AI version on Claude. Sign in to Claude on that device; a free Claude account is enough to start.
  3. Allow the book to use Claude when it asks. Then Pip answers your child's questions in plain words and gives hints when a practice question is hard.

For parents: a Claude account is for adults. Sign in with your own account on your child's device and stay close by while Pip is in use. AI answers count toward your own Claude usage limits. Your child's progress and questions stay on your device and in your own account. The author cannot see them.

By a parent, for parents

Made by a dad for his son, shared free with every family

These books began as notes a father wrote for his own child. Every chapter is reviewed for scientific accuracy by a university professor.
