Connected to your lessonUnderstand
01 / The human problem
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, especially when the learner can keep the original lesson in view and ask for help at the exact confusing moment.
Needing another explanation is not failure. That is being human.
02 / The learning path
One learning path. Four useful moments.
Stay with the lesson you chose. Itzako helps only when you ask. Each stage has one role, so the learner can see what was captured, explained, practised and saved for later review.
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.
03 / Lesson context
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.
04 / Learner control
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.
Lesson context
Study help that stays tied to the lesson.
Itzako keeps the next useful step close to the material: clearer explanation, focused practice and later review when a lesson gets hard.
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.
