Instant answers removed the work that produces understanding. Here the chat box is replaced by a classroom: a teacher, a student who asks the basic questions, and a stronger student who pushes for depth.

You are never only watching. Hints stay hidden until you commit a guess, blanks wait for your intuition, and you can step in as the third student at any moment — by typing or by speaking.

Afterwards a checkpoint, a delayed retention quiz, and a spoken teach-back measure whether the idea actually stayed.
