Supermemory integrates with [Pipecat](https://github.com/pipecat-ai/pipecat), providing long-term memory capabilities for voice AI agents. Your Pipecat applications will remember past conversations and provide personalized responses based on user history.

## Installation

To use Supermemory with Pipecat, install the required dependencies:

```bash
pip install supermemory-pipecat
```

Set up your API key as an environment variable:

```bash
export SUPERMEMORY_API_KEY=your_supermemory_api_key
```

You can obtain an API key from [console.supermemory.ai](https://console.supermemory.ai).

## Configuration

Supermemory integration is provided through the `SupermemoryPipecatService` class in Pipecat:

```python
from supermemory_pipecat import SupermemoryPipecatService
from supermemory_pipecat.service import InputParams

memory = SupermemoryPipecatService(
    api_key=os.getenv("SUPERMEMORY_API_KEY"),
    user_id="unique_user_id",
    session_id="session_123",
    params=InputParams(
        mode="full",            # "profile" | "query" | "full"
        search_limit=10,        # Max memories to retrieve
        search_threshold=0.1,   # Relevance threshold (0.0-1.0)
        system_prompt="Based on previous conversations:\n\n",
    ),
)
```

## Pipeline Integration

The `SupermemoryPipecatService` should be positioned between your context aggregator and LLM service in the Pipecat pipeline:

```python
pipeline = Pipeline([
    transport.input(),
    stt,                           # Speech-to-text
    context_aggregator.user(),
    memory,                        # <- Supermemory memory service
    llm,
    tts,                           # Text-to-speech
    transport.output(),
    context_aggregator.assistant(),
])
```

## How It Works

When integrated with Pipecat, Supermemory provides two key functionalities:

### 1. Memory Retrieval

When a user message is detected, Supermemory retrieves relevant memories:

- **Static Profile**: Persistent facts about the user
- **Dynamic Profile**: Recent context and preferences
- **Search Results**: Semantically relevant past memories

### 2. Context Enhancement

Retrieved memories are formatted and injected into the LLM context before generation, giving the model awareness of past conversations.

## Memory Modes

| Mode        | Static Profile | Dynamic Profile | Search Results | Use Case                       |
| ----------- | -------------- | --------------- | -------------- | ------------------------------ |
| `"profile"` | Yes            | Yes             | No             | Personalization without search |
| `"query"`   | No             | No              | Yes            | Finding relevant past context  |
| `"full"`    | Yes            | Yes             | Yes            | Complete memory (default)      |

## Configuration Options

You can customize how memories are retrieved and used:

### InputParams

```python
InputParams(
    mode="full",               # Memory mode (default: "full")
    search_limit=10,           # Max memories to retrieve (default: 10)
    search_threshold=0.1,      # Similarity threshold 0.0-1.0 (default: 0.1)
    system_prompt="Based on previous conversations:\n\n",
    inject_mode="auto",        # "auto" | "system" | "user"
)
```

| Parameter          | Type  | Default                                | Description                                                  |
| ------------------ | ----- | -------------------------------------- | ------------------------------------------------------------ |
| `search_limit`     | int   | 10                                     | Maximum number of memories to retrieve per query             |
| `search_threshold` | float | 0.1                                    | Minimum similarity threshold for memory retrieval            |
| `mode`             | str   | "full"                                 | Memory retrieval mode: `"profile"`, `"query"`, or `"full"`   |
| `system_prompt`    | str   | "Based on previous conversations:\n\n" | Prefix text for memory context                               |
| `inject_mode`      | str   | "auto"                                 | How memories are injected: `"auto"`, `"system"`, or `"user"` |

## Injection Modes

The `inject_mode` parameter controls how memories are added to the LLM context:

| Mode       | Behavior                                                                                                                                                                |
| ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `"auto"`   | **Auto-detects** based on frame types. If audio frames detected → injects to system prompt (speech-to-speech). If only text frames → injects as user message (STT/TTS). |
| `"system"` | Always injects memories into the system prompt                                                                                                                          |
| `"user"`   | Always injects memories as a user message                                                                                                                               |

## Speech-to-Speech Models (Gemini Live, etc.)

For speech-to-speech models like Gemini Live, the SDK **automatically detects** audio frames and injects memories into the system prompt. No configuration needed:

```python
from supermemory_pipecat import SupermemoryPipecatService

# Auto-detection works out of the box
memory = SupermemoryPipecatService(
    api_key=os.getenv("SUPERMEMORY_API_KEY"),
    user_id="unique_user_id",
)
```
