⚙️ Process (How It Works)

DSAFlowBot works through a multi-phase pipeline that transforms user input into a complete learning experience:

System Architecture Diagram

PHASE 1: USER INPUT & AUTHENTICATION
┌──────────────────────────────────┐
│  User Login                      │
│  Select Language & Topic         │
└────────────┬─────────────────────┘
             │
             ▼
PHASE 2: ROADMAP & DEFINITION GENERATION
┌──────────────────────────────────────────┐
│  Send to AI Model API                    │
│  ├─ Generate Roadmap                     │
│  └─ Generate Definition (in selected     │
│     language & topic)                    │
└────────────┬─────────────────────────────┘
             │
             ▼
PHASE 3: YOUTUBE VIDEO DISCOVERY & FILTERING
┌──────────────────────────────────────────┐
│  Search YouTube for Topic Videos         │
│  Fetch Available Videos                  │
│  Filter Against Quality Rules            │
│  ├─ Video duration                       │
│  ├─ Channel credibility                  │
│  ├─ View count & ratings                 │
│  └─ Relevance score                      │
└────────────┬─────────────────────────────┘
             │
             ▼
PHASE 4: TRANSCRIPT & SUMMARY EXTRACTION
┌──────────────────────────────────────────┐
│  Collect Video Transcripts               │
│  ├─ IF Transcript Available              │
│  │  └─ Use Transcript                    │
│  └─ IF Transcript NOT Available          │
│     └─ Extract & Use Video Metadata      │
│        (Title, Description, etc.)        │
└────────────┬─────────────────────────────┘
             │
             ▼
PHASE 5: QUESTION GENERATION (with Token Management)
┌──────────────────────────────────────────┐
│  Generate Questions According to Rules   │
│  Check Token Count                       │
│  ├─ IF Tokens ≤ Limit                    │
│  │  └─ Generate Full Summary             │
│  └─ IF Tokens > Limit                    │
│     └─ PARTIAL METHOD:                   │
│        ├─ Divide Summary into Parts      │
│        ├─ Generate Questions per Part    │
│        └─ Combine Results                │
└────────────┬─────────────────────────────┘
             │
