Vectorizer

Vectorizer is a Cargo workspace of five crates providing a vector database with multiple transports: a binary MessagePack RPC protocol as its default and fastest interface, a REST API that also powers its React dashboard, a Qdrant-compatible gRPC service, a GraphQL endpoint, and an MCP server exposing 31 tools for AI assistants such as Cursor and Claude Desktop.

It uses AVX2 SIMD-accelerated vector operations with runtime CPU detection, and an optional Metal GPU backend on Apple Silicon. Native SDKs are provided for Rust, Python, TypeScript, Go and C#, and configuration is loaded from layered config files under a config directory.

  • ai·rete·rag

    ai-rete-rag.com

    A platform that pairs a Rete rule engine with retrieval-augmented generation, so deterministic rules decide an outcome and grounded retrieval explains the decision in plain language.

  • Xtriever

    github.com

    A hybrid retrieval engine for retrieval-augmented generation, written in Rust to run on-device on a phone or a laptop, combining lexical BM25 search, dense embedding search, reciprocal-rank fusion and cross-encoder re-ranking with no server.

  • FileFlux

    github.com

    A .NET library that turns PDF, DOCX, HWP and other documents into optimized chunks for RAG systems, through a five-stage pipeline built on high-performance Rust FFI readers.
