About Bip & Bok

Bip and Bok want to know how everything works. In each episode they pick one big idea and work it out together, a small piece at a time.

The first series is How AI Works. It starts with how a computer learns, and why it sometimes gets things wrong.

For curious kids, and for the grown-ups who keep getting asked "but how?"

Made by a person with the help of AI. The end of episode 1 explains who did what.
