I built a tool that queries your data files with SQL or plain English entirely in the browser. Nothing gets uploaded, and it works with your Wi-Fi&LAN off

It's called OmniSelect FileSQL (clientvirt.com). You drop in a file, like a CSV, Excel sheet, Parquet file or even an SPSS/SAS/Stata file, and query it with SQL, or type a question in plain English and get the SQL written for you. Everything happens in your browser tab: no upload, no account, no install. **How it's built:** - A static site with no backend at all. Files are read into memory on your machine and discarded when you close the tab. - The query engine is DuckDB compiled to Web

AI 分析

痛点：隐私敏感数据无法上传云端，需要在浏览器或内网离线环境中用 SQL 或自然语言查询 CSV、Excel、Parquet、SAS、SPSS 等文件。

目标用户：数据分析师、研究人员，以及医疗、金融、政府等有 air-gapped 或数据不能外传要求的企业/组织团队。

证据：Everything happens in your browser tab: no upload, no account, no install. Organisations can license a self-hosted build for their intranet or air-gapped machines, with a written license and a security review pack.

变现：免费 Web 版引流，企业自托管/内网/离线版按年授权，提供书面许可证和安全审查包。

MVP：2周内做一个纯前端 CSV/Excel 查询工具：DuckDB WASM + 文件拖拽 + SQL 编辑器 + 导出 CSV；先不做自然语言，验证隐私查询需求。

竞品：DuckDB WASM、SQLite WASM、Datasette、Observable、CSVFiddle、Harlequin、q、Quadbase

摘要：独立开发者发布 OmniSelect FileSQL，一个纯浏览器端文件查询工具，基于 DuckDB WASM，支持 SQL 和自然语言，不联网、不上传，可查询 CSV/Excel/Parquet/SAS/SPSS 等。免费 Web 版，面向企业提供内网/气隙自托管授权。尚无付费客户或收入数据。
