Show HN: DuckDB Graph Research RAG for Claude Code (github.com)

DuckDB Graph Research has introduced Lattice, a tool that simplifies the creation of a searchable knowledge base using Claude Code, which many users may already subscribe to. Unlike traditional GraphRAG tools that require multiple API keys and extensive setup processes, Lattice provides an efficient two-command workflow: /research and /graph-sync. This allows users to leverage their existing markdown documentation, automatically extract entities, and synchronize that data with an embedded DuckDB database for seamless semantic search capabilities. This innovation is significant for the AI/ML community because it streamlines the documentation and research process, reducing setup time from over 30 minutes to just two. Lattice leverages Claude Code for entity extraction without additional costs, minimizing external dependencies and simplifying workflows. By using DuckDB's vector similarity search for semantic queries, Lattice enhances information retrieval, making it easier to find relevant documentation and insights. As a result, this tool not only boosts productivity but also encourages collaborative research and knowledge management within AI and machine learning domains.
