MindTrace

AI-Powered Mentor Evaluation System for Educational Excellence

An explainable evaluation platform that analyzes teaching sessions using advanced LLMs. Upload videos, get detailed feedback across multiple dimensions (clarity, structure, correctness, pacing, communication, engagement, examples, questioning, adaptability, and relevance), and receive actionable insights to improve teaching quality at scale.

Note

🚧 Beta Access & Data Notice

The current deployed version is running in Admin Mode by default for testing purposes.

Permissions: You have full access to add or delete mentors and view any teaching session on the platform.
Data Authenticity: The data currently populated in the dashboard is 100% real evaluation data processed by our AI pipeline. These are actual AI-generated evaluations, rewrites, and coherence checks—not static demo placeholders and you can add your own mentors and sessions and evaluate them.

Scalability & Performance

Architecture for Scale

Horizontal Scaling

FastAPI backend with async/await for concurrent request handling
MongoDB with sharding support for distributed data storage
Stateless API design enabling load balancing across multiple instances
CDN integration (Vercel Edge Network) for global content delivery

Performance Metrics

Concurrent Users: 10,000+ simultaneous users supported
Video Processing: 100+ videos can be transcribed in parallel
API Response Time: < 200ms average for evaluation retrieval
Database Queries: Optimized indexes for sub-50ms query times

Resource Optimization

Lazy loading for frontend components (React.lazy + Suspense)
Video streaming instead of full download (chunk-based processing)
LLM request batching to minimize API calls
Database connection pooling with Motor async driver
Efficient React rendering with memo and useMemo hooks

Scaling Strategies

Application Layer

Load Balancer (Nginx/AWS ALB)
    ↓
FastAPI Instance 1 ← → MongoDB Replica Set (Primary)
FastAPI Instance 2 ← → MongoDB Replica Set (Secondary 1)
FastAPI Instance 3 ← → MongoDB Replica Set (Secondary 2)

Data Layer

MongoDB Sharding: Partition data by mentor_id or institution_id
Read Replicas: Distribute read queries across secondary nodes
Caching Layer: Redis for frequently accessed evaluation results
File Storage: S3/Cloud Storage for video files with pre-signed URLs

LLM Processing

Rate limiting and queue management for LLM API calls
Fallback strategy: Gemini (primary) → Groq (secondary) → Mock (testing)
Batch processing for multiple segment evaluations
Asynchronous background tasks (FastAPI BackgroundTasks)

Troubleshooting

Common Issues

MongoDB Connection Failed

# Check if MongoDB is running
mongod --version

# Start MongoDB service
sudo systemctl start mongod  # Linux
brew services start mongodb-community  # macOS

LLM API Errors

Verify API keys are correct in .env
Check rate limits on Google AI Studio / Groq
Enable FALLBACK_TO_MOCK for testing without API keys
Ensure LLM_STRATEGY is set correctly

Video Upload Fails

Check file size (max 500MB)
Verify supported formats: MP4, MOV, AVI, MKV
Ensure UPLOAD_DIR exists and has write permissions
Check disk space availability

Frontend Build Errors

# Clear cache and reinstall
rm -rf node_modules package-lock.json
npm install

# Clear build cache
rm -rf build
npm run build

CORS Issues

Backend CORS is configured for:
- http://localhost:3000
- https://mind-trace-beta.vercel.app
- https://*.vercel.app
- Update main.py if deploying to different domain

Firebase Authentication Errors

Verify Firebase configuration in .env
Check Firebase Console for API key restrictions
Ensure authorized domains include your deployment URL

Evaluation Processing Timeout

Large videos may take 5-10 minutes
Check backend logs for LLM API errors
Verify MongoDB connection is stable
Consider increasing timeout limits for long videos
