Curriculum organization

Your whole curriculum, in a structure teachers can navigate.

Programs contain blocks. Blocks contain units. Units contain lessons. Lessons are made of activities — with vocabulary, grammar, and CEFR-aligned objectives at every level.

Campuses run sessions. Sessions hold the classes that teach your programs.

  1. Program

    A full course of study, aligned to CEFR levels

  2. Block

    A module within the program

  3. Unit

    A theme with vocabulary, grammar, and objectives

  4. Lesson

    What a teacher delivers in a single class

  5. Activities

    • Vocabulary practice
    • Fill in the blank
    • Discussion questions
    • Role play
    • Listening
    • Writing task

Real language. In the lesson.

YouTube, TikTok, and podcasts — in the same lesson.

Paste a YouTube or TikTok link, or drop in a podcast clip. Students practice with the language they actually hear — and teachers review everything first.

  • YouTube

    Paste a link. It embeds in the lesson — ready to teach from.

  • TikTok

    Short-form video students already watch, turned into language practice.

  • Podcasts

    Drop in a clip. Build listening around real speech.

AI-assisted creation

Start from what you already have. Generate the rest.

Start from objectives, curriculum, source material, or your own instructions. Lexen drafts structured content to review.
  • Lesson and unit drafts from your curriculum
  • YouTube, TikTok, and podcast clips embedded in the lesson
  • Activities: vocabulary, fill-in-the-blank, role play, discussion, writing
  • Supporting images, listening audio, and pronunciations
  • Regenerate one piece at a time

Lesson & activity editor

Generated content is a draft. Teachers make it final.

Everything AI produces lands in an editor. Teachers decide exactly what students see.
  • Edit any generated text, activity, or assessment
  • Add, remove, and reorder activities
  • Regenerate a piece with new instructions
  • Lock shared curriculum so class edits don't drift

Classroom delivery

Teach the lesson from one screen.

Project activities. Move at your own pace. Follow mode brings every student device with you.

  • Live participation, synced to the teacher
  • Vocabulary, listening, writing, discussion, and more
  • Homework and assessments in one place

Why it's different

Why AI belongs inside the teaching workflow

A chatbot can write a worksheet. It can't know your program, your objectives, or what happens after the draft. Lexen's AI is connected to the lesson.

It knows your curriculum

Generation runs inside your programs, units, and lessons — not a blank chat box.

It targets the right level

Lessons and activities match CEFR-aligned objectives for the class.

Output is ready to use

Drafts arrive as editable activities — not a wall of text to reformat.

Teachers review everything

Nothing is used in class until a teacher has reviewed and edited it.

It connects to delivery

The same platform that creates the lesson delivers it — and assesses it after.
