What is Weaviate?

Weaviate is a vector database designed to store and search data using AI-powered semantic understanding. Instead of matching exact keywords, it interprets the meaning behind search queries and returns relevant results based on conceptual similarity. The tool combines vector storage with traditional database features, allowing you to search unstructured data like text, images, and documents at scale. It's built for teams working with machine learning models, generative AI applications, and organisations that need intelligent search capabilities without managing complex infrastructure. Weaviate offers both open-source and managed cloud options, making it accessible whether you're running a proof of concept or a production system.
