A Brief In, A Lesson Out
You stay in control of the result — Cleo produces a first draft, never the final word.
1. Give it the brief
Subject, topic, level, duration and what you want the student to practise. Nothing else is required.
2. Cleo builds the structure
It returns a sectioned lesson with explanations, vocabulary, interactive exercises and an optional homework section.
3. Edit and teach
Every element is editable. Change what you want, then open it in the live classroom.
Not Just Text
Cleo produces the same elements you would have built by hand.
Explanations
Clear written explanations, sectioned and paced for the lesson length you asked for.
Vocabulary
A dictionary of key terms that flows into the student's practice list.
Flashcards
Front-and-back pairs generated from the lesson's own vocabulary.
Interactive exercises
Self-checking tasks built around the topic, not generic filler.
Illustrations
Relevant photography pulled in automatically to break up the material.
Homework
A separate homework section you can assign the moment the lesson ends.
Built To Keep Student Data Out Of It
AI should draft your lessons, not learn from your students.
Only the brief is sent
Cleo receives the subject, topic, level and duration. No names, no student records, no submissions, no files.
No training on your content
We use the OpenAI API under terms that prohibit training foundational models on our inputs and outputs.
Nothing from your calendar
Connected Google Calendar data sits in a separate path and never reaches an AI provider.
