## Features
- Interconnect and retrieve your past conversations, documents, images and audio transcriptions
- Reduce hallucinations, developer effort, and cost.
- Load data to graph and vector databases using only Pydantic
- Manipulate your data while ingesting from 30+ data sources
## Get Started
Get started quickly with a Google Colab <a href="https://colab.research.google.com/drive/1g-Qnx6l_ecHZi0IOw23rg0qC4TYvEvWZ?usp=sharing">notebook</a> or <a href="https://github.com/topoteretes/cognee-starter">starter repo</a>
## Contributing
Your contributions are at the core of making this a true open source project. Any contributions you make are **greatly appreciated**. See [`CONTRIBUTING.md`](CONTRIBUTING.md) for more information.
## 📦 Installation
You can install Cognee using either **pip**, **poetry**, **uv** or any other python package manager.
### With pip
```bash
pip install cognee
```
## 💻 Basic Usage
### Setup
```
import os
os.environ["LLM_API_KEY"] = "YOUR OPENAI_API_KEY"
```
You can also set the variables by creating .env file, using our <a href="https://github.com/topoteretes/cognee/blob/main/.env.template">template.</a>
To use different LLM providers, for more info check out our <a href="https://docs.cognee.ai">documentation</a>
### Simple example
Add LLM_API_KEY to .env using the command bellow.
```
echo "LLM_API_KEY=YOUR_OPENAI_API_KEY" > .env
```
You can see available env variables in the repository `.env.template` file. If you don't specify it otherwise, like in this example, SQLite (relational database), LanceDB (vector database) and NetworkX (graph store) will be used as default components.
This script will run the default pipeline:
```python
import cognee
import asyncio
async def main():
# Add text to cognee
await cognee.add("Natural language processing (NLP) is an interdisciplinary subfield of computer science and information retrieval.")
# Generate the knowledge graph
await cognee.cognify()
# Query the knowledge graph
results = await cognee.search("Tell me about NLP")
# Display the results
for result in results:
print(result)
if __name__ == '__main__':
asyncio.run(main())
```
Example output:
```
# ({'id': UUID('bc338a39-64d6-549a-acec-da60846dd90d'), 'updated_at': datetime.datetime(2024, 11, 21, 12, 23, 1, 211808, tzinfo=datetime.timezone.utc), 'name': 'natural language processing', 'description': 'An interdisciplinary subfield of computer science and information retrieval.'}, {'relationship_name': 'is_a_subfield_of', 'source_node_id': UUID('bc338a39-64d6-549a-acec-da60846dd90d'), 'target_node_id': UUID('6218dbab-eb6a-5759-a864-b3419755ffe0'), 'updated_at': datetime.datetime(2024, 11, 21, 12, 23, 15, 473137, tzinfo=datetime.timezone.utc)}, {'id': UUID('6218dbab-eb6a-5759-a864-b3419755ffe0'), 'updated_at': datetime.datetime(2024, 11, 21, 12, 23, 1, 211808, tzinfo=datetime.timezone.utc), 'name': 'computer science', 'description': 'The study of computation and information processing.'})
