Guided lessons

Lesson structure

A guided lesson opens with the topic, explains why it matters, walks through key concepts, points to the visual map, follows source-supported connections, offers a knowledge check, reviews, and ends at the sources. Every factual scene shows the exact claim it came from; structural scenes only add navigation, not new facts.

Depth levels

Use the Depth control to choose Quick overview, Beginner, Standard, Advanced, or Exam review. Higher depths reveal more concept and connection scenes; the information is always source-grounded, only the amount shown changes.

Playback and focus

• Move with Previous and Next scene, or jump using the scene rail.
• Focus mode expands the lesson to full screen where the browser allows it.
• Play narration uses the browser's speech synthesis when available; the full transcript is always visible.
• Your depth and last scene are remembered locally.

Reduced motion

With reduced motion enabled, scene transitions become immediate. All narration, evidence, and controls remain, so no information depends on animation.
