You can install Cognee using either pip, poetry, uv or any other python package manager.
With pip
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
This script will run the default pipeline:
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:
Natural Language Processing (NLP) is a cross-disciplinary and interdisciplinary field that involves computer science and information retrieval. It focuses on the interaction between computers and human language, enabling machines to understand and process natural language.
