Free for teachers

Free for teachers. It stays that way

Our mission is to make learning better for everyone. As long as a teacher is teaching, the platform is free to them — all of it.

By the numbers

  • 0

    What a teacher pays

  • 1

    Paid tier, and it is for schools

  • 169

    Interactive figures, all included

What “free” means here

This is the whole platform. There is no cut-down free version with a better one underneath it.

What you make for your class

  • An interactive lesson your students play, marked as they go
  • An exam in the real national format, printed to A4
  • A full presentation for the period
  • An illustrated story for young readers
  • Worksheets, quizzes and assignments
  • Interactive figures across maths, physics and chemistry

What you plan before the lesson

  • A lesson plan for a single period
  • A weekly plan on one page
  • A unit plan, first period to final assessment
  • The curriculum spread over the weeks the term actually has
  • Learning objectives you can measure

What you find out afterwards

  • Automatic marking on closed questions
  • A class heatmap, and the misconceptions behind it
  • A report for each student on their own

And across all of it

  • Arabic and English in everything it makes
  • Pages printed right to left, the way they are read
  • No trial period and no countdown
  • No credit card at signup

How the arithmetic works

It is a fair question: somebody has to pay for this. Here is the answer in four steps.

  1. 1

    The teacher pays nothing

    The whole platform, no subscription and no card. What others charge a monthly fee for, we give away.

  2. 2

    Some teachers publish what they built

    Publishing is a decision you make lesson by lesson. It is the reason the tier is free, not a condition of it: keep everything to yourself and you lose nothing.

  3. 3

    The shared library grows

    The next teacher starts from a lesson another teacher built, not from a blank page. That is how the product gains value without a teacher paying for it.

  4. 4

    Schools pay for administrative access

    A school buys seeing its whole staff in one place. That is the revenue, and it pays for the platform every teacher uses for free.

So who actually pays

Schools, and only schools. A school pays for administrative access — seeing the whole staff in one place. The teacher pays nothing either way, whether their school subscribes or not. Not one teacher feature sits behind that line, and we will not move an existing one behind it.

What we will never do with your class

The free tier is funded by school subscriptions, not by student data. These are the limits, written down.

  • We never sell student data

    Not to data brokers, not to marketing companies, not to anyone who buys lists.

  • No ads on any screen

    No advertiser buys your students' attention, because there is no ad space to sell.

  • No training on student work

    What a student writes inside String is not used to train our models.

  • We never publish your work for you

    Every lesson stays private until you choose to publish it, and nothing in your account changes if you never publish one.

If the company's plans change

No company can promise it will never change, and we are not going to make that promise. What we will commit to is narrower and clearer: what is free for a teacher today stays free for that teacher. If we ever build something new that carries a price, it will be new — we will not take a tool you already use and sell it back to you. That is the difference between changing our plans and changing the deal.

Common questions

There is no catch, but there is a reason: schools pay for administrative access, and that revenue pays for the platform teachers use for nothing. There is no cut-down free version and no trial that expires in two weeks.

No. What is free for a teacher today stays free for that teacher, and we will not move a tool teachers already use behind a paywall. If we later build something new that carries a price, it will be an addition rather than the taking back of something we already gave.

Nothing changes for you. A school subscription buys administrative access for whoever runs the school, not teacher tools. A teacher in a subscribing school and a teacher in a school that has never heard of us use the same complete platform.

From schools. A school pays for administrative access — seeing the whole staff in one place — and that is where the revenue comes from. We do not sell data, we do not sell ads, and we do not take a cut of a teacher's work.

They stay yours. What you built is yours and we claim no ownership of it, and you can print any lesson, exam or worksheet and keep it. We are not going to hold your work hostage to keep you.

No. The free tier is funded by school subscriptions and not by student data: nothing is sold, nothing is advertised against, and nothing a student writes trains our models. We hold no compliance certification and will not pretend otherwise, but the list of what we store and why is published on our security and privacy page.
