Build dynamic Agent memory using scalable, modular ECL (Extract, Cognify, Load) pipelines. More on [use-cases](https://docs.cognee.ai/use_cases).

Why cognee?

## 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 notebook or starter repo ## 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 template. To use different LLM providers, for more info check out our documentation ### Simple example 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: ``` 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. ``` Graph visualization:
