Learn anything.

What you give it is what it asks about

Four ways in. Your own material needs an account, and a name is all an account takes.

• Photograph the pages

  Photosynthesis takes place in the chloroplasts. The light reactions happen in the thylakoid membranes, where the energy of light is stored as ATP and NADPH.

  p. 48

  Where in the chloroplast do the light reactions take place?

• Name the book

  Moby-DickHerman Melville, 1851

  What is the name of Captain Ahab’s ship?

• Paste a video transcript

  1. 04:08Think of current as water in a pipe.
  2. 04:12Voltage is then the pressure pushing the water along.
  3. 04:17And resistance is how narrow the pipe is.

  You paste the transcript in yourself. Muizi does not fetch it from a video link yet.

  In the water-pipe picture, what does voltage stand for?

• Describe what you want to learn

  I want to design my own motor controller, but I’ve never done any electronics.

  Why is a diode fitted across the motor when a transistor switches it off?

It’s already been used

• A ninth-grader photographed their Finnish textbook and got 138 questions for the exam.
• 82 questions for a hobbyist who wants to design their own motor controller with no background in electronics.
• 725 ready-made questions across five school subjects, playable without an account.

What it looks like

One round of Finnish: ten questions on dialects and slang, one of them answered wrong. For now the game talks in Finnish, and its ready-made courses follow Finnish schoolbooks.
