Pass Pass is a learning app built for Cameroonian primary pupils — the ones sharing one phone with three siblings, on a class of eighty, revising for the First School Leaving Certificate by lamplight. Lessons, quizzes and past papers work completely offline and cost nothing, forever. And when a child gets stuck, an AI tutor is there — paid for by someone who believes she should have one.
Meet Pim and Pop — the two study buddies who cheer every child through every lesson.
Nothing about Cameroonian children limits them. The maths is the same maths. What differs is how much one-to-one attention a child can get — and that is exactly the thing an over-subscribed classroom cannot give.
In a class that size, a pupil who misses a step in long division may wait weeks to be noticed. By then the class has moved on and she has decided she is "bad at maths".
Past papers, revision booklets and extra lessons are a real household expense. The families who most need the extra practice are the ones who can least buy it.
An app that only works on a strong connection is an app for city children with data bundles. Most learning apps quietly exclude everybody else.
So we inverted the usual design. Pass Pass downloads once and then works with the phone in flight mode. The lessons, quizzes and past papers cost us nothing to serve, so they are free forever — no trial, no unlock, no ads. Only the AI features cost real money per use, and that is precisely where sponsors come in.
Lessons in English Language and Mathematics for Class 3 to Class 6, written against the Cameroon English-subsystem primary curriculum, then broken into short steps a child can finish in the ten minutes before the phone is needed by someone else.
When a child is stuck, she can ask. The tutor does not hand over the answer; it asks her what she tried, finds the exact step where the reasoning broke, and walks her back through it — in simple English, as many times as she needs, without ever sighing.
A child snaps a photo of her homework or her class notes. Pass Pass reads the page, checks her work, marks what is right, and explains what went wrong — turning the exercise book she already has into an interactive lesson. It is the single feature parents ask for first.
A learning tool only works if it fits the whole household — and the school around it.
Nine to twelve years old, working towards the FSLC. She gets a tutor who is never too busy, never impatient, and always available — even at 6am before the water run.
Wants to help with homework but perhaps left school early, or works two jobs. Pass Pass explains the topic so the parent can sit beside the child instead of apologising to her.
Eighty pupils and one of you. Pass Pass takes the repetition and the marking practice off your plate so class time goes to the things only a human teacher can do.
You already send money home for school fees. This is the same instinct, made specific: a named amount that puts an AI tutor in a child's hands, at a school you choose, for a whole year.
Banks, telcos, MoMo operators and NGOs who want visible, measurable community impact — with their name on the free past-paper packs every candidate in the region uses.
A distribution-first education company: free content acquires the users, AI features monetise them, and the same engine ports to every country with a national primary syllabus.
Educators have known for forty years that one-to-one tutoring produces dramatically better outcomes than whole-class teaching — the finding is old and uncontroversial. What was missing was any way to afford a tutor for every child. That is the constraint AI has just removed.
A patient explanation used to cost a human hour. It now costs a few francs. For the first time, the expensive part of good teaching is within reach of a village school.
The children whose parents already pay for extra lessons are getting AI tutors this year. Without deliberate effort, AI does not close the education gap — it doubles it.
We built for the low-end Android, the shared phone and the empty data bundle first. Anything that works there works everywhere. The reverse is never true.
Pointing a chatbot at a child is not teaching. Everything in Pass Pass is shaped by a few stubborn convictions about how primary children actually learn.
Every lesson is one idea, ten minutes, with the prerequisite made explicit. A child who fails a quiz is sent back to the step she actually missed, not to the start of the chapter.
The tutor is instructed to question before it explains and to explain before it solves. A child who is handed answers learns to ask; a child who is questioned learns to think.
Names, markets, francs, distances, foods and exam formats from here — not translated worksheets. A word problem about buying beignets is a word problem a child can picture.
Pim and Pop cheer, streaks build, mistakes are treated as normal and interesting. Much of primary failure is a child deciding early that she cannot. We take that seriously.
Good teaching is empirical. Here is how Pass Pass gets measurably better each term — and the honest state of each piece today.
Which questions does the whole country get wrong? No names, no accounts, no child-level tracking — only aggregate item statistics, the same thing a good exam board looks at.
A question 70% of children fail is usually a badly worded question, not eighty thousand slow children. Those get rewritten and re-measured, term after term.
Practising Cameroonian primary teachers review lessons and past-paper packs before release. AI drafts; a teacher who knows these classrooms signs off.
We sample anonymised tutor exchanges and grade them against our own rubric — did it question first? did it stay on the child's level? did it stay on the syllabus? — and tighten the instructions where it falls short.
Where a topic defeats children nationally, that is useful to every teacher in Cameroon, not just to us. We intend to publish those findings openly.
Every AI answer costs us a few francs of compute. A child whose family cannot spare that will still get the whole syllabus free — but she should get the tutor too. Someone has to pay for it, and it does not have to be her mother.
Bring Pass Pass to your pupils, get sponsored AI places for the ones who need them, and help shape what we build next.
Join as a school →Sponsor one child's AI year, a whole classroom, or an entire school — and put your name on material every candidate in the region uses.
Become a sponsor →You already send money home. Send some of it as an AI tutor, and know exactly what it bought and for how many children.
Give from abroad →The model, the unit economics, and the plan to take Pass Pass from one Cameroonian region to primary classrooms across Africa.
See the plan →A year of AI tutoring for one Cameroonian child costs about the price of a restaurant meal. She will remember it considerably longer.
