## Database Schema

### Core Tables

1. **users** - User accounts with calendar integration tokens
2. **meetings** - Meeting details, platform info, recording status
3. **participants** - Meeting participants with RSVP tracking
4. **agendas** - Meeting agenda items with ordering
5. **transcripts** - Speech-to-text transcripts with timestamps
6. **action_items** - Extracted tasks with assignments
7. **summaries** - AI-generated meeting summaries
8. **ai_conversations** - Chat history with AI assistant
9. **audio_chunks** - Audio segments for transcription
10. **attachments** - Meeting files and documents
11. **organizations** - Multi-tenant support
12. **meeting_analytics** - Meeting statistics

## API Endpoints Summary

### Authentication (8 endpoints)
- POST `/api/auth/register`
- POST `/api/auth/login`
- POST `/api/auth/logout`
- GET `/api/auth/me`
- PUT `/api/auth/profile`
- POST `/api/auth/change-password`
- GET `/api/auth/preferences`
- PUT `/api/auth/preferences`

### Meetings (15+ endpoints)
- CRUD operations
- Start/End/Join/Leave
- Transcript management
- Summary generation
- Action item extraction
- Analytics

### Transcription (6 endpoints)
- Upload audio chunks
- Stream audio
- Start/Stop recording
- Get transcripts
- Download recording

### AI Assistant (7 endpoints)
- Chat with AI
- Get history
- Get insights
- Summarize current
- Identify action items
- Voice generation
- Toggle assistant

### Action Items (6 endpoints)
- List/Show/Update/Delete
- Complete/Reopen
- Reassign

## AI Integration Flow

### Real-Time Transcription
```
1. User microphone → WebRTC → Audio chunks
2. Audio chunks → Whisper API → Text
3. Text → Transcript model → Database
4. Broadcast → WebSocket → All participants
```

### AI Assistant Response
```
1. User message → Meeting context gathering
2. Context + History → GPT-4 → Response
3. Response → Database + Broadcast
4. Optional: Text → TTS → Audio file
```

### Post-Meeting Processing
```
1. Meeting ends → Trigger jobs
2. Full transcript → GPT-4 → Summary
3. Transcript → GPT-4 → Action items
4. Calculate analytics
5. Send summary emails
```
