Meet Cleo, your AI lesson assistant

What Cleo can draft for you, where to find it, and how its monthly allowance works.

Cleo is Classario's built-in lesson writer. You describe what you want to teach; Cleo drafts the material — explanations, interactive exercises, and homework — as ordinary Classario elements you can edit.

What Cleo can do

  • A whole lesson from a subject, topic, level and length.
  • A homework section to go with it.
  • One element at a time — add an exercise to a lesson you are already writing.
  • Regenerate an element you do not like, without touching the rest.

It also finds images for the material it writes, so the draft does not arrive as a wall of text.

Where to find it

  • Generate lesson at the bottom of the sidebar.
  • Create with Cleo AI in the Library.
  • Generate with Cleo AI on the calendar, which drafts a lesson and schedules it.
  • Inside the editor, on individual elements.
The Generate lesson dialog asking for subject, topic, focus, level and duration

Which plan

Cleo is part of Pro and School, and available to everyone during the 14-day trial. There is a monthly allowance of generations rather than an unlimited tap; the Billing page shows where you stand.

Cleo drafts, you teach

Treat the output as a first draft from a keen assistant. It is generated text: read it before class, check the facts and the answer keys, and adjust the level. Everything it makes is a normal material — nothing is locked.
