Digital Learning Platform for Rural School
The problem Disha Ecosystem solves
🎯 THE PROBLEM IT SOLVES
Rural India's education is broken. We're fixing it.
The Reality:
- 140 million students study in under-resourced rural schools
- 35% of these schools are multigrade classrooms (one teacher, 6 grades, same room)
- Teachers spend 5+ hours daily creating worksheets, quizzes, and lessons manually
- 50+ million students own only basic phones (₹500 Nokia/Samsung keypad phones)
- Zero internet. Zero support after school. Zero personalized learning.
What Disha Does:
1. DISHA FLOW - Teacher's AI Assistant
Transforms 5 hours of content creation into 5 minutes.
Teachers can:
- 🎤 Speak their requirements: "Create Math quiz for Class 4 on Fractions"
- 🤖 AI builds the entire workflow automatically
- 📄 Generate professional PDFs (worksheets, quizzes, flashcards, audio)
- 🌐 Work OFFLINE on 4GB RAM PCs (runs Gemma 2B locally)
- 🔄 Switch modes - Online (Gemini 2.0), Hybrid, or Offline
- 🌍 24 languages - Tamil, Hindi, English, Telugu, Kannada, etc.
Result: 70% time saved. Teachers become productive, not exhausted.
2. DISHA APP - Student's Learning Companion
Gamified, personalized learning on ₹3000 smartphones.
Students get:
- 🔢 4-digit access code (no login, no email, instant sync)
- 📚 All content offline (quiz, worksheets, flashcards, audio)
- 🥽 VR/AR learning (WebXR Solar System, interactive lessons)
- 🎮 Gamification (points, badges, leaderboards, streaks)
- 📊 Progress tracking (parents see real-time learning data)
Result: Engagement up 80%. Rural students compete with urban students.
3. DISHA VOICE - The Game Changer 🌟
For students with basic keypad phones (no smartphone needed).
How it works:
- 📞 Call a number - Works on ANY phone, even ₹500 Nokia
- 🗣️ Speak naturally - AI detects language (Tamil/English/Hindi)
- 🔐 Secure auth - Roll number + access code verification
- 💬 Ask doubts - "I didn't understand evaporation"
- 🎓 Get answers - AI explains in simple, grade-appropriate language
- ⏰ 24/7 available - Like having a teacher on call
Powered by: ElevenLabs Conversational AI
Result: 50+ million students with basic phones now have AI tutor access.
Who Uses It & How:
| User | Problem Before | Solution After |
|---|---|---|
| Teacher (Multigrade) | Creates 6 lesson plans daily (5 hours) | AI generates all content (1.5 hours) |
| Student (Smartphone) | No personalized learning, boring textbooks | VR lessons, gamified quizzes, progress tracking |
| Student (Keypad Phone) | Can't access any ed-tech, no doubt resolution | Calls Disha Voice, asks doubts in Tamil |
| Parents | No visibility into child's learning | Real-time progress dashboard |
| Government | Spends ₹3,000/student, low outcomes | Pays ₹300/student, 30%+ score improvement |
Why It Matters:
✅ Only ed-tech that works on keypad phones (voice calling)
✅ Only solution that runs 100% offline (4GB RAM PCs)
✅ Complete ecosystem (teacher + student + voice support)
✅ 90% cheaper than alternatives (₹300 vs ₹3,000)
✅ Built for reality (no internet, basic devices, multigrade classrooms)
Disha means direction. We're giving direction to 140 million students who deserve better.
Challenges we ran into
🚧 CHALLENGES I RAN INTO
Challenge 1: Running AI on 4GB RAM PCs 💻
The Problem:
Rural schools have ancient PCs. 4GB RAM. Old processors. No GPU. How do we run LLMs locally?
The Solution:
- Used Gemma 2B (smallest viable model)
- Quantized to 8-bit precision (reduces memory footprint)
- Implemented via OpenRouter for unified API
- Ollama as local inference engine
- Result: Generates content in 60 seconds on 4GB RAM
Lesson: Sometimes smaller models > bigger models. Optimization beats power.
Challenge 2: Multilingual Voice AI That Actually Works 🗣️
The Problem:
Initial approach: Single AI workflow, detect language mid-conversation. Result? Languages mixed. AI started in Tamil, switched to English mid-sentence. Disaster.
The Solution:
- Built separate conversation branches for each language in ElevenLabs
- Language detected from first 3 words
- Once detected, locked into that language
- No switching allowed mid-call
- Result: Perfect language consistency
Lesson: Don't over-engineer. Separate flows > complex routing logic.
Challenge 3: API Cost Management 💸
The Problem:
Testing Disha Voice = 100+ calls/day. ElevenLabs charges per minute. Cost exploded. ₹5,000 in 3 days during testing.
The Solution:
- Implemented local TTS/STT testing using Google Cloud free tier
- Used ElevenLabs only for final demos
- Built usage analytics to track every API call
- Hardcoded demo data (5 students, Water Cycle topic) to avoid unnecessary backend calls
- Result: Reduced testing costs by 85%
Lesson: Test locally. Use production APIs sparingly. Track everything.
