Support that stays with you
Ask anything about what you're studying. Get explanations, hints and worked steps — including out loud, with voice, and with proper maths.
For students
Study with someone in your corner
The hardest part of learning alone is the moment you get stuck and there is nobody to ask. On CyOku there always is — support that knows the course you are in, gives you a hint before it gives you an answer, and keeps going until it clicks.
What you get
Everything for one subject, in one place
No jumping between a video site, a question app and a revision guide that don't know each other exists. On CyOku the lesson, the practice, the exam and the help all share the same picture of how you're doing.
Courses
Topic explanations and video that build up in order, with quizzes at the end of each section so nothing quietly slips past you.
Practice
Question practice you can point at exactly the topic, level or curriculum you need to fix.
Assessments and reports
Sit a full paper, then read a report that tells you which topics are weak and what to do about them — not just a number.
Learning activities and games
For the drilling that would otherwise be a slog — built from the same course content you're studying.
Progress you can actually see
What's done, what's next, and what needs another pass — so revision stops being a guess.
The moment that matters
What happens when you get it wrong
Getting a question wrong is the most useful thing that can happen to you — as long as somebody helps you understand why. That is the whole job of personalized learning.
- It notices. Not just the wrong answer — the pattern behind it.
- It hints first. The smallest nudge that lets you finish it yourself.
- It explains properly. Worked steps from the reviewed course content.
- It points you at the lesson. The exact page or video that covers it.
- It adjusts. Easier if you're struggling, harder when you're ready.
- It keeps you going. Encouragement that isn't hollow, because it's based on your actual work.
I got 3. The answer says −3. I don't get it.
Your working was right up to the last line — this is a sign slip, not a method problem. When you moved the 3 across the equals sign, what should happen to it?

Ohh. It flips.

Questions
Before you start
Is it really free to try?
Creating an account is free, and selected courses on CyOku are free to take once you're signed in. Other courses are paid — you'll always see the price on the course before you commit to anything.
Which exams and curricula does CyOku cover?
CyOku is a global platform, and the catalogue grows as creators and education providers publish. Rather than promise a list, the honest answer is: search for your subject or exam and see what's live today.
Will the AI just do my homework for me?
No — and that is deliberate. Support leads with hints and questions so you do the thinking. It explains fully when explanation is what helps, but the design goal is that you understand the topic, not that a box gets ticked.
My school uses CyOku. Is this the same account?
If your school set you up, sign in with the username your teacher gave you — no email needed. Your assigned work and your school's courses will be waiting there.
