Lesson schema

The Lesson schema builds a complete, interactive HTML lesson from a single prompt. Just describe the topic and the intended audience — the AI handles structure, component selection, and delivery.

How to trigger it

Ask for a lesson in natural language, in any language:

  • “Create a lesson on photosynthesis for middle school”
  • “Build an interactive activity on the French Revolution”
  • “Make a learning unit on fractions for grade 4”
  • “Didattica sulla Seconda Guerra Mondiale per il liceo”

What you get

A self-contained HTML file you can open in any browser, embed in an LMS, or publish as-is. The lesson includes:

  • A title and learning objectives written in the first person (“I will be able to…”)
  • Content sections using interactive components — accordions, tabs, timelines, galleries, media players, and more
  • Exercises when active practice adds value — multiple choice, fill in the blanks, drag and drop, sorting, essays, crosswords, and more

Exercises are optional. A purely narrative or visual lesson is perfectly valid.

Tips for best results

  • Specify the audience. Grade level, subject, or prior knowledge helps the AI calibrate complexity.
  • Mention the tone. Formal, conversational, playful — the AI adapts.
  • Provide your own media. If you have images, videos, or audio to include, share them in the conversation. The AI will not invent media.
  • Iterate freely. Ask to add an exercise, swap a section format, or change the language — the AI will update the lesson in place.
