From prompt to live class in four steps

The same flow you use in the teacher admin — no separate tooling.

Describe & focus

Enter your teaching prompt, level, length, and skill focus (speaking, listening, writing, reading, grammar).

Structure blocks

AI suggests a flow — or start manually. Reorder, swap types, and tune each block before generating content.

Generate content

Credits power text, images, listening audio, and tasks. Edit titles, descriptions, and regenerate any block.

Share & teach

Publish, copy the link, invite by email, watch students live, and optionally list on Explore for colleagues.

Get started free

Everything to teach, speak, and grow your classroom

AI lesson building, live teaching, student practice, and Lesso Talk voice rooms — one workspace for modern language classes.

Build lessons

Start from one prompt

Describe your class in plain language — AI drafts a full lesson with vocabulary, reading, tasks, and wrap-up in seconds.

Lessons from the latest news

Browse current headlines, pick a story, and turn it into a classroom-ready lesson around topics students care about.

Smart block editor

Drag, reorder, duplicate, or delete any card. You stay in control of pacing and difficulty.

Purpose-built block types

Text, vocab, grammar, listening, images, games, and speaking — each block is tuned for language learning.

AI image generation

Generate scene visuals, flashcard art, and story illustrations without leaving the editor.

Board game blocks

Rich auto-graded tasks

MCQ, fill-in-the-blank, matching, ordering, dictation, flashcards, writing, voice, and more — all in one link.

Live collaborative lessons

Students work through your lesson while you watch progress update in real time and guide speaking tasks.
