Lang Huey: Why We Built an Offline French Teacher for Nigerian Smartboards

"My mother runs a private school in Lagos. She couldn't find a French teacher. So I built one."
— NIT7ER

Every school proprietor in Nigeria knows this specific panic: It is the third week of the term. Your French teacher sends a sudden WhatsApp message resigning for a higher-paying NGO gig or relocating abroad.

Suddenly, your school timetable has a gaping hole.

You have three terrible options:

Scramble to hire a replacement: Specialist French teachers are rare, expensive, and have notoriously high turnover.
Try virtual Zoom classes: You pay ₦60,000 to ₦120,000 every month for an instructor streaming over video. Two minutes into the class, the school Wi-Fi buffers, the generator surges, and forty students are left staring at a frozen screen.
Quietly replace French with free periods: Students miss their syllabus, parents get furious, and when Junior WAEC or BECE exam time comes, the gap is exposed.

We refused to accept any of these options. So we engineered the solution from scratch: Lang Huey.

The Promise: French Class. No Teacher. No Problem.

Lang Huey is a dedicated, 100% offline language delivery engine installed directly on classroom Android smartboards and Interactive Flat Panels (IFPs).

Its core architecture is built around a simple principle:
1 App • 1 Class Level • 1 Language • Offline Forever.

It is not an online portal. It does not require a broadband subscription. It cannot be brought down by a bad network signal or a power blip. Once installed on your board, it runs every single period, without fail.

The Core Innovation: The On-Screen "Teacher Cue Bar"

The biggest bottleneck in running a language class without a specialist isn't the lesson content—it's classroom orchestration. How does a substitute teacher or general staff member run a class if they don't know the difference between “s'il vous plaît” and “merci beaucoup”?

We solved this through the Teacher Cue Bar.

At the bottom of every interactive slide, Lang Huey provides real-time, step-by-step instructions written in clear, Standard English for the supervising staff member:

ON-SCREEN PROMPT:
"Play the audio twice. Ask Row 1 to repeat 'Bonjour !' with high energy."
"Call a student from the back to come to the smartboard and touch the image for 'l'école'."

The software delivers the authentic French pronunciation and interactive drills. The supervising teacher simply acts as the energetic conductor of the room. Zero French knowledge required. Zero embarrassment. Total classroom command.

What Lang Huey Means for Every Stakeholder

1. For School Proprietors & Principals

The Timetable Guarantee: If a teacher is absent or resigns, French class still runs on schedule without a hitch.
Return on Hardware Investment: Nigerian private schools invest millions of Naira into interactive flat panels, only to see them used as expensive chalkboards or YouTube screens. Lang Huey turns that investment into an undeniable competitive advantage.
Exam Assurance: Every lesson maps line-by-line to the official NERDC syllabus (covering Primary 4, Primary 5, and the JSS1 French Pack), preparing students thoroughly for BECE and WAEC exams.
No Recurring Cash Drain: No monthly per-seat licensing fees or streaming bandwidth costs.

2. For Classroom Supervisors & Substitute Teachers

Dignity & Confidence: You don't have to dread covering French periods. The system removes all guesswork.
Structured 30-Minute Lessons: Warm-up, vocabulary introduction, interactive group drills, and quick comprehension checks—all timed and paced automatically.

3. For Parents

Consistent Academic Quality: No more hearing your child say, "Our French teacher didn't come today."
Native Pronunciation: Children learn from clear, studio-grade neural audio rather than local approximations.

4. For Students

Instead of copying dry notes off a chalkboard, students engage with a multi-modal, tactile game:
- Stepping up to the board to tap phonetics and drag words into place.
- Solving Nigerian context math (e.g. counting in Naira at the French market kiosk).
- Cheered on by Huey, the encouraging classroom mascot.

Built for Nigerian Infrastructure Realities

At NIT7ER, we have zero interest in Silicon Valley buzzwords. We don't build "disruptive AI paradigms." We build operational systems that survive the real world.

In Lagos, Abuja, or Port Harcourt, software must withstand:

Sudden NEPA power transitions.
Thick concrete walls that block Wi-Fi signals.
High-volume classrooms where attention is hard to hold.

Lang Huey is engineered specifically for these constraints. It is lightweight, hardware-locked to the smartboard, and executes locally with zero latency.

What's Next

We are currently launching the JSS1 French Pack and primary school modules across select private schools in Nigeria. Following French, the engine will expand to Mandarin Chinese and Spanish, giving Nigerian schools the global language curriculum their students deserve.

French class. No teacher. No problem.
