Every child deserves support at the right time.

In class the material moves fast, and one teacher works with 26 children at different levels. Small difficulties go unnoticed and gradually pile up.

Not because the child cannot do it. Because the difficulty was not noticed in time.

The Accelerated Learning methodology

Albena Yotova and the Intreea team create a digital world that helps children learn with more motivation and engagement and develop their potential.

Intreea is the first platform in the world to digitise the Accelerated Learning methodology, developed by Libyan Labiosa-Cassone. The methodology rests on neuroscience and pedagogical practice.

In Intreea, your child has their own place in the Tree of Knowledge.

The avatar, the little house and the rewards earned along the way grow with everything your child learns. Your child gets an experience of its own, one it wants to come back to every day.

What it looks like on the inside

  • A course screen in Intreea: the intro video, the next lesson on the path, homework with a deadline and the course sections with their status.

    Children can always tell where to continue from

    Each section unlocks once the previous one is complete. Points, streaks and rewards move your child along a single path, and homework comes with a deadline. All your child sees is the next step.

  • An exercise in Intreea: dragging numbers into ascending order, with every item read aloud.

    A variety of task types

    The material is practised through different kinds of tasks, so your child really comprehends it instead of memorising it.

  • The end of a lesson in Intreea: “Well done!”, 100 experience points, 10 gems, a streak of five correct answers and progress towards the next level.

    Success is visible right away

    Points are awarded for every correct answer, with streaks and rewards at the end of the lesson. Progress is shown on the very same day.

  • A magical artefact in Intreea: gloves that give a second try after a wrong answer, without breaking the streak.

    Artefacts with a part to play in the lesson

    What is earned is spent on magical artefacts that change something in the learning process: for example, a second try after a wrong answer without breaking the streak. Every artefact has a role in learning.

How Intreea moves your child forward

  1. Finds where your child is

    From the first exercises it sees what your child already knows and where they get stuck.

  2. Gives the next step

    Every lesson is within reach. Nothing already learned is repeated, nothing is skipped.

  3. Shows you the progress

    A short lesson every day, with a clear end, and in the parent profile you see everything by section.

For schools and teachers

One test, as many versions as there are students

An environment that supports the teacher's work and makes every student's needs visible.

  • Every student gets a different version

    You choose which lessons and how many questions. Each student gets their own version at the same difficulty. Copying stops making sense.

  • Works inside the lesson period

    It does not replace the lesson; it makes it easier to run and keeps the class with you. Set tests and homework, and decide who can do them and until when.

  • Mastery, not memorising

    How far the class has got and what share of the answers are correct are two different numbers. You see both, by section and by student.

Questions parents ask

Which grades is Intreea for?

Intreea currently offers maths and Bulgarian language and literature for grades 5, 6 and 7 (with preparation for the NVO exam in grade 7), and English at levels A1, A2 and B1. Maths and Bulgarian language and literature for grades 1 and 4 are coming soon. Our aim is to offer learning for students from grade 1 to grade 12 across a wide range of school subjects.

What can my child learn with Intreea?

The platform currently offers maths and Bulgarian language and literature for grades 5, 6 and 7 (with preparation for the NVO exam in grade 7), and English at levels A1, A2 and B1. More grades in maths and in Bulgarian language and literature are coming soon, along with more subjects.

How much time a day does my child need to spend?

One short lesson a day, with a clear start and end. How long it takes depends on the child. No overload and no free time lost.

How is Intreea different from other platforms?

Most platforms offer ready-made video content for everyone. Intreea finds the specific child's gaps and builds a personalised path, adapting in real time. It is not a static course.

How do I know it will work for my child?

Intreea is not one course for everyone. It starts with a diagnostic that finds exactly where your child is and builds an individual learning path around them. The algorithm follows the pace and adapts the content continuously. And you see every step in real time.

I do not want my child in front of a screen even more.

We understand the concern. What matters is the quality of the time. One short lesson a day: active, focused and with a clear goal. No passive content. The child thinks, solves and moves forward. Thanks to the accelerated learning method, results come sooner.

Do I need to be actively involved as a parent?

Not necessarily. The child works on their own. You have a parent profile with full visibility: what has been learned, what comes next, how they are progressing. You follow along when you want to, without having to sit beside your child.

If we are not happy, can we cancel?

The monthly plan has no commitment: you can cancel at any time. No hidden fees, no complications.

Knowledge is worth something when you can use it.

Fourteen days are free. Enough to see whether your child sits down to it on their own.
