About TopK
TopK is an AI-native search engine and document database designed for enterprise and development teams building production-grade retrieval systems. It supports hybrid search in a single composable query, merging vector similarity, keyword (BM25) matching, metadata filtering, and faceted search for precise retrieval and ranking. The platform enables multi-vector, multi-modal indexing with unlimited vector representations per document across text, images, video, and audio. TopK is engineered for high performance at scale, handling millions of documents with sub-10ms latency at high query-per-second rates and high write throughput for demanding workloads. It offers integration options for production stacks, including SDKs for Python, JavaScript, and Rust, as well as connectors for Postgres, MongoDB, and Kafka. TopK targets predictable performance and cost for web-scale, multi-tenant enterprise deployments by combining dense and sparse retrieval with filtering and custom scoring in a unified query model.
