Store & Search
Billions of Embeddings
High-performance vector database built for AI applications. Store embeddings, run similarity search, and power RAG systems at petabyte scale with sub-10ms latency.
Why HLD Vector DB
Petabyte Scale
Store billions of vectors with horizontal scaling. Add nodes on demand without re-indexing or downtime.
Hybrid Search
Combine semantic similarity with keyword filters. Full-text search, metadata filtering, and vector search in one query.
Sub-10ms Queries
Optimized indexing (HNSW, PQ, diskANN) delivers consistent sub-10ms latency at any scale.
Enterprise Security
AES-256 encryption at rest, role-based access control, SOC 2 Type II compliance, and private VPC deployment.
Enterprise-Grade Capabilities
Everything you need to build production AI applications — from prototyping to petabyte-scale deployments.
Multi-Vector Support
Store and query multiple vector embeddings per document. Perfect for multi-modal and cross-encoder retrieval.
Real-Time Updates
Add, update, or delete vectors in real-time. No batch jobs or re-indexing windows needed.
Metadata Indexing
Index metadata fields for fast filtering. Combine vector similarity with structured queries.
Time-Based Retention
Auto-expire old data with TTL policies. Keep only what matters with configurable retention.
Geographic Distribution
Replicate data across regions for compliance and latency. Read from the closest replica.
Full-Text Search
BM25-based keyword search alongside vector search. Hybrid retrieval for better recall.
Integrations
Use Cases
RAG Applications
Power retrieval-augmented generation with semantic search over your documents, knowledge bases, and archives.
Recommendation Systems
Build personalized recommendations using vector similarity over user behavior, preferences, and content embeddings.
Semantic Search
Enable natural language queries over unstructured data. Find relevant documents by meaning, not keywords.
Anomaly Detection
Identify outliers and anomalies by querying for vectors most dissimilar from normal patterns.
Simple, Predictable Pricing
Pay for storage and operations separately. No surprise bills. Starter plan includes 1M vectors free.
