GPTGraph is a free Chrome add-on developed by Saas-AI. It is a powerful tool that converts unstructured natural language into a knowledge graph. Whether you have the synopsis of your favorite movie, a confusing Wikipedia page, or a video transcript, GPTGraph can generate a graph visualization of entities and their relationships.

With GPTGraph, you can update the existing state of the graph or create a new structure through successive queries. For example, you can inject new information through nodes and edges or change the color of certain nodes to represent different data.

To ensure accurate rendering, GPTGraph utilizes a few-shot prompt to guide GPT-3/chatGPT in understanding the required JSON formatting. However, one major drawback is the latency issue. Due to the nature of OpenAI API calls, it may take up to 20 seconds to receive a response.

If you need a powerful tool to convert unstructured natural language into knowledge graphs, GPTGraph is a great choice. Try it out and explore the possibilities!
