About

Hi, I’m Levi! 👋 I’ve spent years working with data and grew tired of the constant trade-off between power and privacy. I watched Excel crash on large files and felt uneasy uploading sensitive data to the cloud just for a quick chart. That’s why I built TopZ—a browser-native data workbench designed to give you 100% control over your data. My goal is to empower analysts and privacy-sensitive teams to handle millions of rows without ever letting a single byte leave their device. I’m a big believer in "Local-First" software and the incredible power of DuckDB-Wasm. When I'm not coding, I'm exploring new ways to simplify complex data workflows for everyone. Excited to be part of this community and learn from you all! 🚀

AI analytics without uploading your data - Would this change your workflow?

Hey everyone!

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.

Before I launch, I'd love to hear your thoughts:
