Hey Product Hunt! ๐Ÿ‘‹ 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 โ†’ 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 settingโ€”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! ๐Ÿ™
