Yes. BRIQ runs DuckDB compiled to WebAssembly (DuckDB-WASM) entirely inside your browser tab - your data is loaded and queried locally and never uploaded to a server, which sidesteps IT approvals and privacy concerns. You import CSV, Parquet, JSON or a .duckdb file (it handles ~500MB files, 4M+ rows) and ask questions in plain English; an LLM writes the SQL and DuckDB-WASM runs it client-side.
It is built on SQLRooms, an open-source React toolkit for AI-powered analytics, and supports multiple LLM providers (OpenAI, Anthropic, Google, Ollama). TigZig's customized build adds DDL/DML support and CSV / Parquet / Excel export.

Building something like this? How I work covers the rates, the availability and what I take on.
