Topic explanations
Written lesson content that carries the teaching — not captions under a video.
Courses
A path through the topic, not a pile of videos
Watching a video is not the same as learning something. A CyOku course is structured so the student is doing something at every step — reading, watching, answering, playing, asking — and help is there the moment it stops making sense.

What's in a course
Six things, working together
Exactly what a course contains depends on what its creator built — but this is the shape a CyOku course is designed around.
Instructional video
Where watching it worked through is genuinely what makes it click.
End-of-section quizzes
A check before moving on, so a gap doesn't quietly follow the student into the next chapter.
Activities and games
Built from the course's own content, for the repetition that would otherwise get skipped.
Ask a question, any time
Answers come from this course’s reviewed content, so the explanation matches what is being taught.
Progress tracking
What's finished, what's next, and what needs another pass — visible to the student, and to a school or parent where enabled.
