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. ``` ### cognee UI You can also cognify your files and query using cognee UI.
