The best way to learn math is throught practice. TXTBK eliminates the two biggest barriers to STEM success in Africa: language and reliable content access. Built on pre-calculated problems — not AI — every problem is 100% accurate, works offline, and speaks the student's mother tongue.
Unlike textbooks or AI tutors, TXTBK uses pre-calculated logic to create an inexhaustible learning environment built specifically for sub-Saharan Africa's infrastructure.
Each problem type generates unlimited unique examples. A student never sees the same calculation twice until mastery — across 300+ modules from primary arithmetic to university-level matrix algebra.
By avoiding Generative AI entirely, TXTBK guarantees 100% mathematical accuracy. Deterministic code follows immutable rules — even a 1% error rate is a major pedagogical failure.
A lightweight application for e-readers, tablets, and smartphones. Once loaded via USB or local hotspot, it requires zero cellular data. Install-and-forget for unstable connectivity areas.
Neuroscience shows abstract concepts are best learned in a child's mother tongue. TXTBK localizes into national languages so students focus purely on mathematical logic.
Optimized for devices in the field: low-cost smartphones, tablets, and E-ink readers. Our partners distribute this hardware and TXTBK clothes them with inexhaustible content.
Paper wears out and costs money to ship. TXTBK is permanent digital infrastructure, offered free of charge to NGO, school and government partners.
A direct comparison against paper textbooks and Generative AI tutors.
| Feature | TXTBK | Paper Textbooks | Generative AI |
|---|---|---|---|
| Internet Access | Not Required — 100% Offline | ✓ Not Required | ✗ Required |
| Math Accuracy | 100% Deterministic Logic | ≈ High but Static | ✗ Hallucination Risk |
| Exercise Volume | Infinite — Dynamic | ✗ Very Limited | ✓ Infinite |
| Distribution Cost | Near-Zero — Digital | ✗ Very High | ≈ High — API Costs |
| National Languages | Yes — Field Optimized | ✗ Rarely | ≈ Limited |
| Hardware | Mobiles, E-readers, Tablets | ≈ Physical Only | ✗ Modern Devices Only |
| Step-by-Step Solutions | Every Problem, Guaranteed | ≈ Some Only | ≈ Inconsistent |
Current Economist at Housing, Infrastructure and Communities Canada, specializing in AI and Automation. Former Economist at Global Affairs Canada. Master's in Economics and CFA Charterholder. Author of EconBook — an illustrated poetry book on economics. Built TXTBK to bring world-class math to every classroom on Earth.
The digital economy needs Africa. Help us deliver free, unlimited math in mother tongues — and unlock a generation's potential.
Every dollar funds the translation of math problems into mother tongues and helps us reach partner organizations already in the field. These are not just math problems. They are the first steps toward global careers and financial independence for a generation ready to shape the future of a continent.
