An innovative Nigerian EdTech called ExamBuddie is offering an AI-powered study solution built on Telegram to help secondary school students prepare for national examinations, including the West African Examinations Council (WAEC), Joint Admissions and Matriculation Board (JAMB), and National Examinations Council (NECO). With a database of over 41,000 past questions and automated explanations, the platform combines custom analytics and artificial intelligence to deliver accessible, data-efficient test preparation for learners nationwide.
TechPolyp spoke with Alhassan Adeiza Hassan, founder of ExamBuddie, about how his experiences in the National Youth Service Corps (NYSC) inspired the project, the decision to build on Telegram over traditional mobile applications, how the platform leverages AI to improve learning outcomes, and his long-term plans to scale accessible education infrastructure across West Africa.
How Classroom Bottlenecks Inspired a Low-Data Mobile Solution
The idea for ExamBuddie originated during his NYSC year in Oyo State, where he taught basic science and physics in a local secondary school. During weekend tutorial sessions, he observed a persistent challenge: students consistently lacked physical past question booklets due to cost constraints.
When students attempted to use existing web-based revision platforms, they encountered severe performance bottlenecks. On low-end mobile devices operating on slow networks, web pages took up to 20 seconds to load a single question, leading to high drop-off rates and frustration. Drawing on his background in program management, Hassan conducted structured surveys to gather direct student feedback, confirming that hardware limitations and poor internet speeds were major barriers to digital learning.
ExamBuddie was conceived to eliminate these friction points by bringing comprehensive exam preparation directly into the lightweight messaging environments students already use every day.
Technical Architecture and Strategic Platform Selection
Although WhatsApp was initially considered as the primary delivery channel, Hassan switched to Telegram because WhatsApp’s per-message API fees were cost-prohibitive for a bootstrapped project targeting low-income students. Telegram offered zero message costs alongside low data consumption—requiring less than 10 megabytes per day—and eliminated registration friction such as email verification.
While ExamBuddie maintains a multi-component architecture comprising a landing page, an admin dashboard, a Telegram bot, and a Telegram mini-app, user data revealed that students overwhelmingly prefer the speed and simplicity of the straightforward Telegram bot.
The platform’s back-end is engineered using Node.js and TypeScript, with data stored in a PostgreSQL database housing over 38,000 active questions and detailed student performance logs. The bot runs on the Telegraph framework, the administration interface is built with React Native, payments are processed via Paystack, and the entire system is hosted on Railway infrastructure. To power accurate automated explanations, Anthropic’s Claude AI is carefully integrated into the editorial workflow, prioritising educational precision and fact-checking over raw generation speed.
Adaptive Progress Tracking and AI-Driven Learning Management
To maximise study efficiency and address broader educational concerns regarding automated tools, ExamBuddie incorporates targeted analytics to identify specific learning gaps. The system tracks each student’s performance across subjects and sub-topics directly within the admin layer.
Rather than offering passive question banks, the platform deploys retention scripts that send automated daily study reminders containing questions customised to a student’s designated weak points. When a student correctly answers three consecutive questions on a previously weak topic, the system logs the mastery milestone and dynamically transitions them to new study material.
Editorial Rigour and Question Bank Quality Control
Building a reliable automated study platform required overcoming major data quality hurdles. While sourcing past WAEC, NECO, and JAMB questions, Hassan discovered that digitising content from existing online archives introduced widespread transcription errors, missing options, and defective diagrams.
To enforce high academic standards, Hassan personally audited the question repository, verifying correct answers and manually excising corrupted or unsolvable questions from the live PostgreSQL database. This rigorous human-in-the-loop validation ensured that automated explanations generated by Claude AI were grounded in accurate reference data.
Monetisation Model Built for Purchasing Power Realities
To accommodate the financial constraints of Nigerian secondary school students—a demographic where over 2 million candidates register for JAMB annually—ExamBuddie uses a freemium pricing strategy tailored to local purchasing power.
New users receive a 14-day free trial granting unrestricted access to premium features and AI explanations. Following the trial, the free tier continues to offer practice questions and basic progress tracking, while capping AI-generated explanations at five per day.
For full access, ExamBuddie offers a monthly plan at 1,500 Naira, a three-month family plan at 3,500 Naira, and an annual subscription at 5,000 Naira. This structure offers a cost-effective alternative to physical past question booklets, which often cost upwards of 2,000 Naira for a single subject booklet, while delivering interactive progress tracking and instant automated tutoring.

Navigating Development Delays and Early Technical Hurdles
Building ExamBuddie required navigating significant operational and technical obstacles. Delaying the launch to August 17th, the primary challenge involved resolving question bank inaccuracies and fixing a pre-launch bug that prevented diagrams from rendering properly in the Telegram bot interface.
As a non-technical product manager leading technical execution, Hassan personally learned database query operations to troubleshoot schema errors and fix image rendering pipelines directly. Resolving these bottlenecks delayed launch plans by an extra week but resulted in a stable, resilient platform capable of serving thousands of simultaneous requests seamlessly.
Key achievements following launch include steady student adoption, enthusiastic user feedback, and securing repeat paying subscribers within the first two months of operation.
The Path Ahead: B2B School Partnerships and Pan-African Expansion
Over the next three to five years, Hassan plans to scale ExamBuddie beyond Nigeria to serve candidates taking WAEC examinations in Ghana, The Gambia, Sierra Leone, and Liberia. Product development plans also include expanding the question bank to cover narrative literature comprehension and practical science modules.
Strategically, ExamBuddie is moving toward a hybrid business-to-business (B2B) distribution model. By partnering directly with secondary schools and tutorial centres, the platform plans to provide dedicated teacher dashboards. These tools will enable educators to assign targeted practice modules, monitor real-time classroom analytics, and track individual student performance automatically.
Advise for Early-Stage African Innovators
Reflecting on his journey as a sole founder, Hassan stresses the importance of rapid execution over passive validation. He urges early-stage African entrepreneurs to launch early, gather direct user feedback, and refine products based on real-world usage patterns.
Managing marketing, customer support, database administration, and product strategy simultaneously as a single operator highlighted for him the necessity of extreme focus. He advises aspiring founders across the continent to concentrate on building simple, localised solutions for clear operational problems rather than transplanting foreign tech trends into markets where basic infrastructure constraints dictate user behaviour.
