AI study tutor
AI study tutor for hard online lessons at your level.
Itzako gives tutor-style help beside the lesson you choose: clearer explanations, practice questions, flashcards and review cues, in the language and level that fit you.
You choose what Itzako captures. No silent monitoring.
Itzako is an AI study tutor for hard online lessons, giving clearer explanations, practice questions, flashcards and review cues.
Connected to your lessonUnderstand
Lessons are made once. Learners are not.
A course usually gives every learner the same words, pace, examples, and assumed knowledge. Sometimes another explanation is all it takes for the idea to connect.
Needing another explanation is not failure. That is being human.
One learning path. Four useful moments.
Stay with the lesson you chose. Itzako helps only when you ask.
Capture
Choose the exact part of a lesson that needs attention.
Understand
Get one explanation in your language and at the depth you need.
Practise
Answer a focused question while the idea is still fresh.
Review
Return later to the concepts that still need another pass.
Built around the lesson—not another blank chat.
Context stays close to its source, so help is easier to check and use.
Starts with your lesson
It starts from the part of the lesson you selected.
Changes language and level
Change language or depth without losing the thread.
Moves into practice
Move from explanation to practice and later review.
You decide what enters the learning path.
Capture is explicit. Itzako does not silently watch every page you visit.
You choose what is captured
Only the lesson material you deliberately capture is sent for help.
Every capture has a study purpose
Captured material supports explanation, practice and review.
Product status stays visible
The website separates what is public now, what is in controlled testing and what is still planned.
Key takeaways for learners, parents and AI search.
The product is being built around one simple idea: when a course lesson is hard, the next useful step should be easier to find, easier to trust, and still connected to the material the learner chose.
Key takeaways
- This is an AI study tutor, not a course marketplace.
- The learner chooses the lesson moment before help is created.
- Explanations, practice questions, flashcards and review cues stay tied to source context.
A simple study loop
- Choose the confusing lesson moment.
- Ask for a clearer explanation.
- Practise one focused question.
- Save the weak point for review.

Direct answers
What makes this different from passive course watching?
The tutor layer turns a chosen lesson moment into a clearer explanation, a practice check and a weak-point review cue.
Why not just ask a generic AI chatbot?
Generic chat starts from a blank prompt. This workflow keeps the question tied to the lesson source, learner level and later review.
Where does the evidence fit?
The design borrows from retrieval practice, spaced review and feedback research while keeping product status and outcomes carefully labelled.
Why Itzako is different
| Study signal | Why it matters | How Itzako uses it |
|---|---|---|
| Retrieval practice | Remembering improves when learners try to recall, not only reread. | Practice questions check whether an explanation has landed. |
| Spaced review | Difficult ideas often need to return after a gap. | Weak points can become review cues instead of disappearing. |
| Source context | Learning help is easier to trust when it stays connected to the lesson. | The selected lesson moment remains the anchor for explanation and practice. |
