TopZ

Hey Product Hunt! 👋 I'm the maker of TopZ, and I'm excited to share what I've been building. **The Problem** As someone who frequently works with data, I've always been frustrated by a common dilemma: - Cloud analytics tools are powerful, but they require uploading sensitive data - Local tools keep data private, but they lack modern AI features For anyone handling confidential information—financial records, customer data, research datasets—this trade-off feels unacceptable. **The Solution** TopZ eliminates this choice entirely. Everything runs in your browser: 🔒 **True local processing** - Your Excel, CSV, JSON, and Parquet files are processed using DuckDB WASM. Nothing ever touches our servers. 🤖 **Privacy-first AI** - When you ask a question in natural language, the AI only sees your column names and data types. Your actual data values stay completely private. ⚡ **Instant results** - Drag and drop files, ask questions, get answers. No complex setup required. **What you can do with TopZ:** - Ask "show me top 10 customers by revenue" → get SQL + results - JOIN multiple tables together - Generate charts with one click - Export results to Excel or CSV - Write custom SQL with our Monaco editor **Tech behind it:** - DuckDB WASM for blazing-fast in-browser queries - Vue 3 + TypeScript frontend - ECharts for visualization **Try it now** - no account required. Just visit topzdata.com, drag in a file, and start analyzing. I'd love to hear your feedback! What features would make this more useful for you? Any questions about how the privacy model works? Thanks for checking out TopZ! 🙏
