# BRIQ App: DuckDB AI in Browser - 500MB Files, 4M+ Records, No Database Setup

BRIQ App: DuckDB AI in Browser. 500MB files. 4M+ records. Natural language queries. All in your browser.

No database credentials or host required. Just upload a flat file - it converts to DuckDB in-browser and you query in plain English.

No hosting costs. No DB setup. Your data doesn't leave your browser except for the LLM API call. Not just analysis - you can merge, append multiple files, transform data. Session based, so data is temporary. I've tested this with files up to 1.5 GB. Auto converts CSV, TSV and other flat files. Good for quick cuts when you have large datasets and just want to analyze without setting up infrastructure.

Open Source App. Built on SQL Rooms AI from [sqlrooms.org](https://sqlrooms.org/) by Ilya Boyandin, with some customizations for my use cases. Source Code in 'Docs' section.

In fact the whole React app is also available as a single file HTML (Link on App site). Double click the HTML file and run it from your local windows folder without any hosting and server. Modify it as you want.
