pany 0.1.0
PostgreSQL-native semantic search engine with multi-modal support (Beta)
License: MIT
Requires Python: >=3.9
Keywords: semantic-search, vector-database, postgresql, embedding, similarity-search, multimodal, rag

# Pany

**⚠️ Beta Software**: This is early-stage software. API may change between versions before v1.0.0.

Semantic search that works inside PostgreSQL. Upload documents and images, then search them with natural language.

Instead of setting up a separate vector database like Pinecone or Weaviate, Pany uses your existing PostgreSQL database with the pgvector extension.

📖 **[Technical Architecture](ARCHITECTURE.md)** - Detailed system design and implementation

## Install and Run

```bash
pip install pany
pany
```

Go to http://localhost:8000 to upload files and start searching.

### Requirements
- Python 3.9+
- PostgreSQL with pgvector extension
- 4GB RAM minimum

### Configuration

```bash
# Custom database
export DATABASE_URL="postgresql://user:pass@localhost:5432/mydb"

# Custom port
pany --port 8080

# Or use Docker
git clone https://github.com/laxmanclo/pany.cloud.git
cd pany.cloud
docker-compose up -d
```

## What it does

**Upload stuff**: Drop PDFs, images, text files into the web interface
**Search naturally**: Type "find the red car" or "contract with Microsoft" 
**Get results**: Finds semantically similar content, not just keyword matches

Works with text and images. You can search for images using text descriptions, or upload an image to find similar ones.

## Code Examples

```python
from pany import PanyClient

client = PanyClient()

# Upload files
client.upload_file("product_catalog.pdf", project_id="store")
client.upload_file("car_photo.jpg", project_id="store")

# Search with text
results = client.search("red sedan", project_id="store")

# Search with image
results = client.search_by_image("my_car.jpg", project_id="store")
```

## SQL Integration

The main advantage over other vector databases is that you can join search results with your existing data:

```sql
SELECT 
    products.name, 
    products.price, 
    search.similarity_score
FROM products 
JOIN semantic_search('comfortable shoes', 0.7) search 
    ON products.id = search.content_id
WHERE products.in_stock = true
ORDER BY search.similarity_score DESC;
```

This is impossible with most vector databases because they're separate systems.

## Why PostgreSQL?

Because you probably already have PostgreSQL running your app. Instead of:
1. Setting up another database (Pinecone, Weaviate, etc.)
2. Keeping data in sync between systems
3. Learning new APIs and query languages
4. Paying monthly fees

You just add pgvector to your existing database and you're done.

## API

REST endpoints for integration:

```bash
# Upload content
curl -X POST http://localhost:8000/embeddings \
  -F "file=@document.pdf" \
  -F "project_id=myproject"

# Search
curl -X POST http://localhost:8000/search \
  -H "Content-Type: application/json" \
  -d '{"query": "find something", "project_id": "myproject"}'
```

## How it works

1. **Embedding**: Uses CLIP model to convert text and images into vectors
2. **Storage**: Saves vectors in PostgreSQL using pgvector extension  
3. **Search**: Finds similar vectors using cosine similarity
4. **Results**: Returns content ranked by similarity score

The CLIP model means you can search across different types of content - find images with text queries, or text with image queries.

## Common use cases

- **Product search**: Upload product catalog, let customers search "red leather shoes"
- **Document management**: Search PDFs and docs with natural language
- **Media libraries**: Find images by describing what's in them
- **Knowledge bases**: Semantic search through support docs

## Environment variables

# Results: [{"name": "Red Nike Air Max", "similarity": 0.89}, ...]
```
**ROI**: 15-25% conversion rate increase = $50k-200k/year additional revenue

### **Customer Support: Instant Knowledge Base**
**Problem**: Agents spend 10+ minutes finding answers, customers wait
**Solution**: Semantic search across all documentation
```sql
-- Find answers across all support docs
SELECT document, answer, similarity 
FROM semantic_search('password reset not working', 'support_docs')
WHERE similarity > 0.8;
```
**ROI**: 60% faster resolution time = 2-3 additional customers served per hour

### **Legal/HR: Document Discovery**
**Problem**: Lawyers bill $500/hour searching through contracts
**Solution**: Natural language search across all legal documents
```python
# Find all contracts mentioning liability clauses
results = pany.search("liability and insurance provisions", project="legal")
```
**ROI**: Save 20 hours/week = $10k/week = $520k/year savings

### **Real Estate: Property Matching**
**Problem**: Clients describe dream home, agents manually search listings
**Solution**: Semantic search combining text + property images
```python
# "Modern kitchen with granite countertops near good schools"
results = pany.search(client_description, project="listings")
```
**ROI**: 3x faster property matching = serve 3x more clients

## 🏗️ Architecture: PostgreSQL + CLIP + FastAPI

```
┌─────────────────┐    ┌──────────────────┐    ┌─────────────────┐
│   Web Widget    │    │   FastAPI        │    │  PostgreSQL     │
│   Dashboard     │◄──►│   + CLIP Model   │◄──►│  + pgvector     │

└─────────────────┘    └──────────────────┘    └─────────────────┘
```

**Why This Stack Wins:**
- **PostgreSQL**: ACID compliance, backups, joins, familiar
- **CLIP**: Multi-modal embeddings (text ↔ images) 
- **FastAPI**: Modern async Python, auto-documentation
- **Docker**: One-command deployment anywhere

## 📊 Performance

### **Benchmarks** (tested on 4-core, 8GB RAM)
- **Upload speed:** ~2MB/sec document processing
- **Throughput:** 100+ concurrent searches
- **Storage:** ~1KB per document embedding
- **Accuracy:** 85-95% relevance for semantic queries

### **Scaling Guidelines**
- **Small team (1-10 users):** 2GB RAM, 2 cores
- **Medium business (10-100 users):** 8GB RAM, 4 cores  
- **Large organization (100+ users):** 16GB+ RAM, 8+ cores
- **Database:** Scales linearly with PostgreSQL
