AI Content Generation

LEIA uses multiple AI models and pipelines to produce complete learning experiences from structured course data.

Lesson Content

The lesson generation pipeline produces full lecture content including:

• Overview & learning outcomes — What the student will learn
• Lecture body — MDX-formatted text with code blocks, diagrams, and interactive elements
• Knowledge checks — Inline quizzes and exercises
• Key terms — Glossary definitions for important concepts

POST /api/v1/lessons/{lessonId}/generate-content
POST /api/v1/courses/{courseId}/lessons/generate-all

Slide Generation

Slides are generated using the nano-banana illustrated method. You choose a visual template and LEIA produces a slide deck with:

• Per-slide illustrations matching the template style
• Narration scripts synchronized to each slide
• Voice-over audio tracks

Available templates: whiteboard, flat-illustration-corporate, doodle-notebook, handwrittenchalkcasual

POST /api/v1/courses/{courseId}/lessons/generate-slides

Video Export

Once slides are ready (slidesStatus: READY), export them as MP4 videos:

POST /api/v1/courses/{courseId}/lessons/generate-videos

Job Tracking

All generation tasks run asynchronously. Monitor progress via:

GET /api/v1/courses/{courseId}/jobs
GET /api/v1/jobs/{jobId}

Language Configuration

Control the output language with the languageConfig object available on most endpoints:

{
  "languageConfig": {
    "contentLanguage": "ko",
    "tutorLanguage": "ko",
    "supportedLanguages": ["ko", "en"],
    "culturalContext": "Korean workplace training"
  }
}
