Show HN: Browser-based data analysis with LLM AI that never sees your data

Built a privacy-first approach to AI-assisted data analysis. The challenge: how do you let AI help with SQL queries without exposing sensitive data? Solution: AI only receives table schemas (column names + types). It generates queries based on structure alone, which run locally via DuckDB WASM. All processing happens client-side. Supports CSV, Parquet, JSON, Excel up to several GBs or bring from HuggingFace, S3, etc and start asking questions.
