PRODUCT OVERVIEW
What is Weaviate?
Weaviate is an open-source AI database for storing, indexing, and searching high-dimensional vectors at scale, forming a foundation for search, retrieval-augmented generation, and agents. The platform bundles a vector database, built-in embeddings generation from text and images, a Query Agent that turns natural-language questions into optimized database queries, and Engram, a managed memory and context service that helps agents remember and personalize experiences. Teams can self-host the open-source project or use Weaviate Cloud, which adds managed operations, console tools for querying and exploring collections, and usage-based AI services. It suits developers and AI teams building production search and RAG applications, with a free tier, pay-as-you-go Flex, and prepaid Premium options.
