Hey Product Hunt! 👋 I'm the maker of CSVLens. Here's the story: I kept running into the same frustration: I'd get a CSV export from our CRM/database/whatever, and I just wanted to ask "what's our revenue trend?" But my options were: 1. Upload it to some SaaS tool (not happening with customer data) 2. Spend 30 mins in Excel pivot table hell 3. Fire up a Jupyter notebook None of these felt right for a 2-minute question. So I built CSVLens. The key insight: **DuckDB can run entirely in your browser via WebAssembly.** That means we can execute real SQL on your data without it ever leaving your computer. Combine that with Claude AI for natural language → SQL translation, and you get something magical: drop a CSV, ask a question, get a chart. No upload. No infrastructure. No SQL knowledge needed. **Some things I'm proud of:** - Privacy isn't a setting—it's the architecture - Large files load in seconds (try it with a 100MB CSV!) - The AI picks the right chart type automatically - You can load multiple CSVs and join them **What I'd love feedback on:** - What features would make this indispensable for you? - Any edge cases where the AI struggles? Happy to answer any questions. Thanks for checking it out! 🙏
