Personalized AI Teacher-Coach · Private-lesson learning Courses · Practice · Assessments

A private lesson that adapts with you

Learn with an AI teacher-coach that stays with you through the session: it follows your level and your difficulties, teaches when teaching is needed, asks before it explains, offers a hint before the answer, builds practice around what you got wrong, and helps you choose the next step together.

Alongside it, CyOku carries the standard products too: Courses, Practice and Mock Exams. Each uses AI differently — and Practice deliberately not at all.

Demonstration only — a real course adapts using everything the student has done, not three questions.

Two ways to learn

A taught session, or material you work through

Both are built on the same expert-reviewed content. What differs is whether someone is teaching you through it.

Private-lesson format

AI Teacher-Coach

A teacher-coach runs the session with you, the way a one-to-one lesson runs. It knows what you have already done, notices where you stall, and decides with you what to do about it.

What a session looks like

Teaches the idea when teaching is what you need
Asks, instead of only presenting — and watches your answer
Offers a hint before the solution, so the thinking stays yours
Explains fully once you have had a real go
Builds practice, activities or a game around the gap
Steps back to the earlier idea when that is the real blocker
Reviews with you, then you choose the next step together

It is an AI teacher-coach, not a human teacher, and it teaches from CyOku's expert-reviewed course content.

See how a session works

Work at your own pace

Structured Learning

Material you move through yourself. AI does a different job in each one — and in Practice, none at all.

Courses

A lecture and lesson path through a subject. AI answers your questions as you go, and turns what you are studying into learning games.
Practice

Question and test banks on a topic you choose. No AI here — just the questions and your answers.
Assessments

Mock exams under real conditions. AI marks the written answers and turns the result into a report you can act on.

Browse the catalogue

Which of these a given course offers depends on the course, the subject and — for school students — the settings their school has chosen.

What CyOku gives you

The four products, in detail

One of these teaches you; the other three are yours to work through. Each stands on its own, and what you do in one shows up in the others.

Personalized Learning

An AI teacher-coach runs the session with you: it teaches, asks, hints, sets practice and agrees the next step with you.

Personalized Learning · Your AI teacher

Too many books, videos and websites. Where do you even start?

Free books, video playlists, websites, notes: there is more material than anyone could ever study, and your exam will not wait. You don't need more of it. You need someone to show you where to start, what to skip and when you have done enough.

That is exactly what your CyOku teacher is for.

We make your study plan together

Tell your AI teacher your goal and how much time you have. You leave with a clear plan, not another list of links.

The right video, game or question for your level

No more searching. Each lesson brings exactly what you need next: a short video for the idea, a game to practise, questions that grow with you.

You always know what's next

Your teacher remembers where you stopped and what trips you up, so every session picks up the thread and moves you forward.

Courses

Lessons you take part in, not lessons you sit through

A CyOku course is not a folder of videos. It is a structured path through a topic, where the student is doing something at every step — reading, watching, answering, playing, asking.

Clear explanations written to be understood, not skimmed.
Video where seeing it worked through is what helps.
Quizzes at the end of each section so nobody moves on with a gap.
Learning activities and games for practice that would otherwise feel like a chore.
Ask a question at any point and get an answer grounded in this course.
Progress tracking that shows what is done, what is next and what needs another pass.

Practice and Assessments

A score is the least useful thing a test can tell you

Practice builds the habit. Assessments put it under real conditions. What matters is what comes after: what the student knows, what they missed, which topics need work, and what to do about it.

Practice → feedback → improvement

Work through questions by subject, topic, level, curriculum or course, and see where you stand straight away.

Four question types, one report

Multiple choice, true/false, multiple answer and open-ended — with intelligent evaluation of open answers where it is supported.

CyOku for schools

One loop: assign, support, see, act

Schools are where CyOku matters most. A teacher sets the work, the student does it with support alongside, and the teacher sees what happened — at student level and class level.

The teacher assigns

A topic, a practice set or a full assessment — to a student, a group or a whole class.

The student works with support

Hints and explanations arrive when a topic gets difficult — not answers on demand.

The teacher sees what happened

Results as they arrive, plus the topics a class keeps getting wrong — so the next lesson can target them.

Parents can follow along

Where the school enables it, families see progress too — the same picture, no surprises.
