## ⚡ Give your AI agents real memory in 3 lines

```python
from neurogram import Agent

adam = Agent("adam")
adam.remember("User prefers concise, technical responses")
context = adam.think("How should I explain this API?")
```

That's it. Your agent now has **persistent, searchable, evolving memory**.

## 🧠 What is Neurogram?

Most AI agents today are **stateless** — they forget everything after each conversation. Neurogram changes that.

Neurogram is an **AI Memory OS** that gives agents human-like memory:

| Memory Type | Human Analogy | Neurogram Feature |
|-------------|--------------|-------------------|
| **Semantic** | Knowing what a router is | `agent.remember("Docker is a containerization platform")` |
| **Episodic** | Remembering yesterday's meeting | `agent.learn(topic="API design", outcome="User liked REST")` |
| **Procedural** | Knowing how to ride a bicycle | `agent.learn_procedure("Deploy", steps=[...])` |
| **Importance** | Important memories persist | Automatic scoring + decay |
| **Forgetting** | Unused memories fade | `agent.decay()` — Ebbinghaus curve |

Unlike simple vector stores, Neurogram implements a **complete cognitive memory architecture**.

## 🚀 Installation

```bash
# Core (zero dependencies beyond numpy)
pip install neurogram

# With sentence-transformers (better embeddings)
pip install neurogram[embeddings]

# With FastAPI server
pip install neurogram[server]

# Everything
pip install neurogram[all]
```

**JavaScript/TypeScript:**
```bash
npm install neurogram-js
```

---

## 📖 Quick Start

### Single Agent

```python
from neurogram import Agent

# Create an agent — memories persist across sessions
agent = Agent("Nova", description="Coding assistant")

# Store memories
agent.remember("User's project uses FastAPI + PostgreSQL")
agent.remember("User prefers type hints in Python code")

# Learn from experience
agent.learn(
    topic="Code review",
    action="Suggested type hints",
    outcome="User appreciated it",
    lesson="Always suggest type hints"
)

# Get context for LLM prompts
context = agent.think("How should I help with this Python code?")
# → "Relevant memories:
#    - User's project uses FastAPI + PostgreSQL
#    - User prefers type hints in Python code"

# Search specific memories
results = agent.recall("user preferences")
for r in results:
    print(f"[{r.relevance_score:.2f}] {r.memory.content}")
```

### Multi-Agent System

```python
from neurogram import Neurogram

brain = Neurogram()

# Each agent has isolated memory
adam = brain.create_agent("Adam", description="Researcher")
nova = brain.create_agent("Nova", description="Coder")

adam.remember("Transformers are the dominant NLP architecture")
nova.remember("User's stack: FastAPI, Docker, K8s")

# Memories don't leak between agents
adam.think("NLP")   # → finds transformer memory
nova.think("NLP")   # → empty (Nova doesn't know about NLP)
```

### Memory-Augmented LLM

```python
from neurogram import Agent
from openai import OpenAI

agent = Agent("assistant")
client = OpenAI()

def chat(user_message: str) -> str:
    # Get relevant memories
    context = agent.think(user_message, format_style="structured")

    response = client.chat.completions.create(
        model="gpt-4",
        messages=[
            {"role": "system", "content": f"You have memory:\n{context}"},
            {"role": "user", "content": user_message},
        ]
    )

    answer = response.choices[0].message.content

    # Learn from this interaction
    agent.learn(topic=user_message[:50], action="answered", outcome="responded")
    return answer
```

## 🔌 Pluggable Backends

### Embedding Engines

| Engine | Quality | Speed | Dependencies |
|--------|---------|-------|-------------|
| `NumpyEmbeddingEngine` | ⭐⭐ | ⚡⚡⚡ | None (default) |
| `LocalEmbeddingEngine` | ⭐⭐⭐⭐ | ⚡⚡ | `sentence-transformers` |
| `OpenAIEmbeddingEngine` | ⭐⭐⭐⭐⭐ | ⚡ | `openai` + API key |

```python
from neurogram import Agent
from neurogram import LocalEmbeddingEngine

# Use sentence-transformers for better quality
agent = Agent("nova", embedding_engine=LocalEmbeddingEngine())
```

### Storage Backends

| Backend | Best For |
|---------|----------|
| `SQLiteBackend` | Development, single-agent (default) |
| Custom backends | Implement `StorageBackend` interface |

---

## 🧪 Memory Server (REST API)

Run the Neurogram server for multi-language access:

```bash
pip install neurogram[server]
neurogram server --port 8000
```

API docs at `http://localhost:8000/docs`

```bash
# Create agent
curl -X POST http://localhost:8000/agents \
  -H "Content-Type: application/json" \
  -d '{"name": "adam"}'

# Store memory
curl -X POST http://localhost:8000/agents/adam/remember \
  -H "Content-Type: application/json" \
  -d '{"content": "User prefers dark mode"}'

# Search memory
curl -X POST http://localhost:8000/agents/adam/recall \
  -H "Content-Type: application/json" \
  -d '{"query": "UI preferences"}'
```

### JavaScript/TypeScript Client

```typescript
import { Neurogram } from "neurogram-js";

const brain = new Neurogram("adam", { serverUrl: "http://localhost:8000" });

await brain.create("Research assistant");
await brain.remember("User studies machine learning");

const memories = await brain.recall("user interests");
const context = await brain.think("What should I recommend?");
```

## 🧬 Importance & Forgetting

Neurogram uses biologically-inspired memory dynamics:

**Importance Score** = α×Frequency + β×Recency + γ×Emotion + δ×Feedback

- **Frequency**: Memories accessed more often strengthen
- **Recency**: Recent memories are naturally more vivid
- **Emotion**: Emotionally charged memories persist longer
- **Forgetting**: Ebbinghaus exponential decay curve

```python
agent = Agent("nova")

# Frequently accessed memories become stronger
for _ in range(10):
    agent.recall("important topic")

# Run decay — low-importance memories get pruned
forgotten = agent.decay()
print(f"Forgot {forgotten} faded memories")
```
