**HippocampAI** is a production-ready, enterprise-grade memory engine that transforms how AI systems remember, reason, and learn from interactions. It provides persistent, intelligent memory capabilities that enable AI agents to maintain context across sessions, understand user preferences, detect behavioral patterns, and deliver truly personalized experiences.

> **The name "HippocampAI"** draws inspiration from the hippocampus - the brain region responsible for memory formation and retrieval - reflecting our mission to give AI systems human-like memory capabilities.

**Current Release:** v0.4.0 — Major feature release with memory consolidation, multi-agent collaboration, and SaaS capabilities.

## Package Structure

HippocampAI is organized into two main components for flexibility:

| Package | Description | Use Case |
|---------|-------------|----------|
| `hippocampai.core` | Core memory engine (no SaaS dependencies) | Library integration, embedded use |
| `hippocampai.platform` | SaaS platform (API, auth, Celery, monitoring) | Self-hosted SaaS deployment |

```python
# Core library only (lightweight)
from hippocampai.core import MemoryClient, Memory, Config

# SaaS platform features
from hippocampai.platform import run_api_server, AutomationController

# Or use the main package (includes everything, backward compatible)
from hippocampai import MemoryClient
```

---

## Quick Start

### Installation

```bash
# Core library (lightweight - 10 dependencies)
pip install hippocampai

# With SaaS features (API, auth, background tasks)
pip install "hippocampai[saas]"

# With specific LLM providers
pip install "hippocampai[openai]"     # OpenAI support
pip install "hippocampai[anthropic]"  # Anthropic Claude
pip install "hippocampai[groq]"       # Groq support

# Everything (development, all features)
pip install "hippocampai[all,dev]"
```

### Your First Memory (30 seconds)

```python
from hippocampai import MemoryClient

# Initialize client
client = MemoryClient()

# Store a memory
memory = client.remember(
    "I prefer oat milk in my coffee and work remotely on Tuesdays",
    user_id="alice",
    type="preference"
)

# Recall memories
results = client.recall("work preferences", user_id="alice")
print(f"Found: {results[0].memory.text}")
```

**That's it!** You now have intelligent memory for your AI application.
