Hey Product Hunt! 👋 Built this because I was tired of tax calculator sites that upload your salary data to their servers to show you a number a 7-year-old could compute. The hard constraint was: if it can run in the browser, it runs in the browser. That forced some interesting engineering — Italian property tax alone has 8,100+ municipalities each with different rates, so I pre-render a static HTML page for every single one at build time using Angular SSG. The AI tools (background removal, depth maps) were the most fun — Transformers.js + WebGPU means the model runs on your GPU, not ours. remove.bg uploads your photo to their servers. We literally can't, even if we wanted to. Would love feedback on: what tools would be most useful for you? What countries should I prioritize next?
