# Meeting Assistant API

FastAPI orchestration backend for Meeting Assistant - middleware between Mobile App, Whisper, and Ollama.

## Architecture

```
Mobile App → FastAPI API → Whisper (transcription) + Ollama (AI analysis)
                        → PostgreSQL (data) + Redis (queues/cache)
                        → Celery Worker (async processing)
```

## Quick Start

```bash
cp .env.example .env
docker-compose up -d
docker-compose exec api alembic upgrade head
```

## Processing Pipeline

1. Audio uploaded → saved to storage/
2. Celery task queued
3. Audio sent to Whisper for diarized transcription
4. Transcription sent to Ollama for parallel analyses:
   - `minutes` - Structured meeting minutes
   - `sentiment` - Emotional tone analysis
   - `psychological` - Behavioral patterns
   - `communication` - Communication quality feedback
   - `summary` - Executive summary
5. Status updated to `completed`
6. WebSocket notification sent

## Environment Variables

See `.env.example` for all configuration options.

## Development

```bash
# View logs
docker-compose logs -f api

# Run migrations
docker-compose exec api alembic upgrade head

# Create new migration
docker-compose exec api alembic revision --autogenerate -m "description"

# Check celery worker
docker-compose logs -f worker
```
