# Hystersis

**Give your AI agents persistent memory that compounds over time.**

Hystersis is an open-source memory infrastructure for AI agents. It provides semantic search, knowledge graphs, and procedural memory that grows with every interaction.

## Why Hystersis?

* **Memory That Adapts** - Agents learn from past interactions
* **Knowledge Graphs** - Understand relationships between entities
* **Semantic Search** - Find information using natural language
* **Multi-Agent Support** - Shared memory across agent teams
* **85% Compression** - Efficient storage without losing context

## Quick Start

```python theme={null}
from hystersis import Hystersis

client = Hystersis("https://api.hystersis.com", api_key="your-key")

# Create a memory
memory = client.create_memory(
    content="User loves machine learning",
    user_id="user-123"
)

# Search semantically
results = client.search("deep learning AI")
```
