I'm about to launch TopZ - a privacy-first data analysis tool that runs 100% in your browser.
The core idea: You can use AI to analyze Excel, CSV, and JSON files without ever uploading your data. Everything is processed locally using DuckDB WASM, and the AI only sees your column names to generate SQL queries.
Own your data with TopZ. AI-powered analysis that runs 100% in your browser—your files never upload.
Ask questions in natural language. AI generates SQL by reading only column names, not your actual data.
Excel, CSV, JSON & Parquet supported. GDPR & HIPAA compliant by design.
