True to your course material
The AI works from your document, using your teacher’s notation and definitions, and cites the page for each passage. It’s not a generic summary found online.
How it works
How Classy works
From your file to a complete revision session in minutes. Here’s what happens at each step, and what the AI actually does.
In short: you upload your course material, the AI reads it in full, splits it into 3 to 12 topics and creates a structured explanation, a mini-video and a quiz for each one. The outline and summary video are ready in 1 to 2 minutes; the topics follow one by one.
The steps
Create your account
A username, an email address (to recover your account) and a password. Your first month of Pro is free.
Upload your course material
Drag and drop your files or select them on your phone; you can add several for the same course (up to 20), in different formats:
- PDF, PowerPoint (.pptx), Word (.docx), text (up to 50 MB);
- up to 20 photos of handwritten notes or a board;
- a lecture recording (MP3, M4A, WAV…, 45 minutes maximum).
Tell us what you need
Your level (lower secondary school, upper secondary school, university), what you’re struggling with (‘I don’t understand elasticities, exam on Thursday’) and, if you have any, past papers or exercises from your teacher. This context guides the analysis.
Classy analyses your course material
The AI reads the whole document, including diagrams and tables in PDFs. It identifies your teacher’s concepts, definitions, formulae and examples, then writes the outline, key ideas and summary video script. Allow 1 to 2 minutes.
Watch the summary video
While the topics are being prepared (1 to 3 minutes each, in order), you get an overview of the course in a video.
Study topic by topic
Each topic has its own page: key point, explanation, intuition, analogy, worked example, interactive graph, cause-and-effect chain, common pitfalls, key takeaways and an exam-style exercise. Each passage cites its source page.
Practise
Quizzes with explanations at the end of each topic, marked open-ended questions, unlimited exercises, then a full mock exam marked out of 20, with a marking scheme and worked answers.
Revise right up to exam day
Enter your exam date: Classy plans your revision and quizzes you again on your mistakes at the right time. A podcast, a one-page revision sheet and a mind map round it all off.
What the AI does, and what it doesn’t
Accurate visuals
Graphs are plotted from equations and formulae are typeset in LaTeX: no approximate AI-generated images.
No ready-made homework
Classy explains, helps you practise and marks your answers. It doesn’t do your homework for you: the aim is for you to understand and be able to do it yourself.
Mistakes can happen — and be reported
AI can make mistakes. That’s why every explanation links back to its source, and there’s a button to report an error.
