What is Weaviate?
Weaviate is a cloud-native vector database that stores objects and vectors together to enable large-scale semantic search. It combines vector similarity search with keyword filtering, retrieval-augmented generation (RAG), and reranking in a single query interface. At import time it can vectorize automatically with integrated models (OpenAI, Cohere, HuggingFace, etc.), or you can supply precomputed embeddings directly. You can install it yourself with Docker or Kubernetes, or use the fully managed Weaviate Cloud built on the same technology.
- Storing, indexing, and searching high-dimensional vectors
- Query Agent that turns natural-language questions into DB queries
- Built-in embedding generation for text, images, and more
- Engram, a personalization feature that learns and adapts per user
- Vector + keyword hybrid search
- Multi-tenancy, replication, and RBAC
- Python, Go, TypeScript, and JavaScript SDKs, plus GraphQL and REST APIs
Who uses Weaviate and for what
- RAG systems
- Semantic and image search and recommendation engines
- Chatbots and content classification
