Your First Lesson

You're looking at a rich text lesson — the most common lesson type. Teachers write these in Markdown, and the platform renders them with full formatting.

But rich text is just one of eight lesson types a teacher can use:

What Rich Text Can Do

Formatted Text

Teachers can use bold, italic, strikethrough, inline code, and links. They can create lists, tables, and blockquotes.

Math

The platform renders LaTeX math. Inline: E = mc^2. Or as a block:

\int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}

This is especially useful for physics, chemistry, and mathematics workbooks.

Diagrams

Teachers can embed flowcharts, sequence diagrams, and other visualizations using Mermaid:

sequenceDiagram
    participant S as Student
    participant AI as AI Assistant
    participant T as Teacher
    S->>AI: "I don't understand this concept"
    AI->>S: Explains with examples
    S->>AI: "Can you give me a practice problem?"
    AI->>S: Generates a problem
    S->>T: Asks in class discussion
    T->>S: Provides deeper context

Code Blocks

For programming courses, syntax-highlighted code:

def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n - 1) + fibonacci(n - 2)

Callouts

Tip: Teachers use callouts to highlight important information, warnings, or interesting asides.

Other Lesson Types

You've already seen a whiteboard lesson in the previous section. Coming up, you'll see a video lesson and hear an audio lesson.

Each type has its own player — the video player has chapters and checkpoint exercises, the audio player has a waveform visualizer, and the whiteboard player lets you scrub through the drawing timeline.

Next up: a video walkthrough of the platform.
