Your curriculum is already here, and AI works inside it

You upload no book and no file. You pick the grade and the subject, and the units, lessons and performance indicators are already there — with AI writing each lesson its guide, its plan, its map, its summary, its worksheet and its quiz, in ten versions each, so you pick the one that looks like your class.

  • No uploads, and no setting up before the year
  • Ten versions of every artifact
  • And AI is what writes them

What is in it

A curriculum is not a file you carry, it is a place AI works in

The difference between pasting a lesson into a general tool, and the lesson living in the system with its indicators, its class and its exams.

  • The curriculum is here, not uploaded

    Pick the grade and the subject, and the units and their lessons appear. No file, no setup week.

  • The performance indicators are written

    Every lesson has its indicators, and AI writes everything else from them.

  • Eight things for every lesson

    A guide, a plan, a map, a summary, an audio overview, flashcards, a quiz and a worksheet.

  • Ten versions of each

    Ten summaries, ten mind maps, ten worksheets, so you pick the one that looks like your class.

  • AI works inside the lesson

    No copying and pasting: the lesson is in front of it, with its indicators and what the class did before it.

  • The textbook lives inside the class

    Not a separate library: the curriculum's lessons sit in the class's own spine.

  • What you pick becomes an activity

    A worksheet becomes homework, a quiz becomes an exam, and its marks enter the record.

  • In Arabic and English

    The lesson, its indicators and everything written about it, in both directions.

Nothing to upload

You pick the grade and the subject, and your year starts

No PDF to upload, no curriculum typed in by hand, and no week lost before the first lesson. The curriculum is there before the school signs up, and the performance indicators are written with every lesson.

  • Units and lessons ordered the way they are taught
  • And the performance indicators with every lesson
  • And not one setup step before you begin

What AI writes

Eight things for every lesson, and you write none of them

You do not open a second tool to make them, or paste the lesson text into another window. The lesson is here, its indicators are here, and the tools work on it directly.

  • Teaching guide

    How the lesson is taught, step by step.

  • Lesson plan

    Objectives and phases, and what the teacher and the student do in each.

  • Mind map

    The whole lesson in one branching picture.

  • Summary

    The core idea on a single page.

  • Worksheet

    Questions ready to print, or to send to the class as homework.

  • Quiz

    Questions that mark themselves, and whose scores enter the class record.

  • Flashcards

    Terms and definitions, for a quick review before the exam.

  • Audio overview

    The lesson as sound, for revising on the way.

And each of them comes in ten versions, not one you either take or leave.

Ten versions

One worksheet does not fit every class

So AI writes ten of everything — ten summaries, ten mind maps, ten worksheets — and you pick the one that looks like your students. The choice is the teacher's, not the system's.

  • You pick a version instead of writing one from nothing
  • And swap it if it does not suit the class
  • And every version is finished, not a draft

A reading, not a decoration

The whole lesson in one picture

The map is not a drawing attached to the lesson: AI reads the lesson and its performance indicators, then draws what branches from what, and what depends on what.

The content above is an example from a states-of-matter unit, not the product's library.

The lesson plan

Ordered phases, and what each person does in each

Not a title and three objectives: phases, and in each one what the teacher does, what the student does, and how what they learned is checked — written from the lesson and its performance indicators.

How it connects

From the curriculum to the class to the record, with nothing copied or pasted

The textbook is not an edge of the system, it is its beginning. What is written from it ends as an activity in the class, a mark in the record, and news for the family.

Who sees what

One textbook, four ways of using it

The teacher picks, the student learns, the family knows where they are, and the office sees the curriculum as it is actually taught.

  • The teacher

    • Opens the lesson and finds eight things written for them
    • Picks the version that looks like their class, out of ten
    • And turns what they picked into homework or an exam with one button
  • The student

    • Reads the lesson, and revises with the flashcards and the summary
    • And does the quest, and its points count in their class
  • The parent

    • Knows which unit your child is on now
    • And sees what the teacher approved, and no more
  • The office

    • Sees the curriculum as it is actually taught, not as it was planned
    • And buys no content and uploads no curriculum before the year

The difference

A scanned book and a general tool, and a curriculum AI works inside

By those we mean what schools do today: a PDF of the book, and a general AI tool you paste the lesson text into so it writes something.

  • Where it starts

    A PDF and a general tool
    From a file you copy out of, and copy out of again for every lesson.
    String
    From the lesson itself, which is in the system before the school signs up.
  • What you get

    A PDF and a general tool
    The teacherOne piece of text, which you take or ask for again in other words.
    String
    AI agentsEight things for every lesson, in ten versions each.
  • Does it know your class

    A PDF and a general tool
    No. It does not know the performance indicators, or what the class did before this lesson.
    String
    It knows the unit and its indicators, and the lessons the class has already done.
  • What happens to what is written

    A PDF and a general tool
    The teacherIt stays in a window, gets copied into a document, then printed.
    String
    StringIt becomes an activity in the class, and its marks enter the record on their own.

General tools are excellent at writing, but they do not know your class's curriculum, its performance indicators, or what your students did last week.

Questions about textbooks

What schools ask before they start preparing the year.

No. You pick the grade and the subject and find the units, lessons and performance indicators ready, with AI working inside them directly.

AI writes them from the lesson and its performance indicators, and the teacher picks among the versions and changes what they want.

Because one worksheet does not fit every class. You pick the one that looks like your students, and swap it if it does not suit them.
