The Problem

Standard edtech was not built for this.

At the end of 2024, 123 million people were forcibly displaced globally. Among them, 49 million were children under 18. For many, school is one of the few stable structures left.

In refugee-impacted schools in Uganda, learners spoke up to 51 different languages, two-thirds of observed lessons required more than one language, and nearly a third of teachers could not speak any home language used by their students.

Between 10% and 33% of displaced children show clinical signs of depression. Among unaccompanied youth, PTSD rates can reach 85%. These children are not failing school. School, as it was designed, is failing them.

The Solution

One laptop. One router. A school that works.

The teacher's laptop runs the server. Students connect from phones, tablets, or computers. Core AI learning features run locally with no internet required, while selected online tasks can use larger models when connectivity is available.

01

Translate and Learn

Students upload a textbook page, photograph, PDF, or pasted text. Gemma 4 creates a conceptual translation into the student's language, then supports learning with summaries, checking questions, and related topics.

02

AI Tutor

Every student gets a private tutor adapted to topic mastery. The tutor adjusts explanation depth, uses Socratic guidance, and communicates progress through calm, encouraging milestones.

03

Live Class Translator

As the teacher speaks, OptiLearn transcribes and translates in real time. Students see the lesson in their chosen language, then receive structured notes after class.

How It Works

Set up in minutes. Run for years.

  1. Install on the teacher's laptop

    Download OptiLearn and run setup. It installs dependencies, prepares the model, builds the curriculum index, and configures the server.

  2. Connect the classroom

    Use the laptop hotspot or a low-cost travel router. Students join the classroom WiFi and open the QR code link or optilearn.local.

  3. Students log in with a PIN

    Teachers create student accounts. Each student gets a PIN, enters it once, and stays signed in without email or cloud accounts.

  4. Learning begins

    Students open the tutor, translate material, join a live quiz, or follow the lesson in their language while the teacher watches progress.

  5. Everything is saved

    Session history, quiz results, progress data, translated notes, and reports stay on the teacher laptop and export with the student.

Technology

Serious engineering for serious constraints.

OptiLearn is not a wrapped chatbot. It is a production system built around unreliable hardware, multilingual input, low-literacy users, and zero tolerance for data loss.

The AI pipeline runs Gemma 4 E2B locally through Ollama. Route-specific prompts, retrieval, language validation, and output cleanup keep the release compatible with future fine-tuned models.

Curriculum retrieval uses FAISS with multilingual MiniLM-L12 sentence embeddings. Speech recognition uses offline Whisper, and text-to-speech uses local Piper and MMS routes where voices are available.

FastAPI, SQLite, React 18, Vite, Workbox, PyWebView, mDNS, captive DNS, and dynamic self-signed TLS make the system deployable on donated hardware without outside services.

Impact

Built for 250 million students who standard systems leave out.

Against a $1,051 refugee education baseline, OptiLearn targets under $200 per student using hardware already present in donation programs. It brings AI-supported multilingual learning to places where broadband, subscriptions, and cloud accounts are not realistic.

Open Source

Free. Forever. For Everyone.

OptiLearn is fully open source under the MIT license. NGOs, school systems, governments, and individual teachers can deploy it, modify it, and share it without cost or permission.

We do not charge. We do not collect data. We do not require accounts with us. The server runs in the classroom and data stays there.

Research

Grounded in the evidence.

Every architectural decision traces back to documented conditions in refugee and displacement education: language diversity, teacher shortages, mental health needs, realistic hardware, and the economics of classroom deployment.
