## About

Inillucent is an embedded SQL database written in Rust that supports vector embeddings and semantic search. It features a complete SQLite dialect implementation and stores tables, full-text indexes, and vector indexes in a single file. The engine provides high performance with multi-process access and a Model Context Protocol (MCP) toolset.

## Who it's for

Developers building agentic systems and applications requiring embedded SQL and vector search.

## Use cases

- Building agentic systems requiring semantic and keyword search
- Running fast embedded SQL queries in Python, Node, and shell environments
- Implementing Retrieval Augmented Generation (RAG) applications

## Features

- Complete SQLite dialect implementation with 100% feature parity plus vector support
- Written in Rust with high performance benchmarks
- Vector columns and HNSW indexes for nearest neighbor search
- Combined keyword and vector search via inillucent_search
- Full featured CLI and Model Context Protocol (MCP) toolset
- Single database file supporting multi-process access

## FAQ

### What does Inillucent do?

Inillucent is an embedded SQL database written in Rust that uses a familiar SQL syntax alongside the power of vector embeddings for semantic search. It stores tables, full-text indexes, and vector indexes in a single file and runs inside your program.

### Who is Inillucent for?

Inillucent is designed for developers building agentic systems and applications that need an embedded database with robust vector search and high performance.

### How fast is Inillucent compared to SQLite?

Inillucent is 500% faster than SQLite overall, faster than SQLite on 110 of 116 benchmark workloads, 3300% faster on reads by key, and 70% faster from Python, Node, and the shell.

### Does Inillucent support vector search?

Yes, Inillucent provides comprehensive vector embedding support for semantic search using VECTOR(N) columns and HNSW indexes.

### Does Inillucent require a database server?

No, Inillucent is an embedded database, meaning there is no database server to install or keep running; your program opens a file and sends SQL to a library in the same process.
