  "account": "A free scientific calculator has been developed that displays mathematical equations in a natural format, similar to a physical calculator. This online tool, called OnlineScientificCalc, eliminates the need for signups or downloads, offering an instant experience. The calculator replicates the layout of a Casio fx-991, featuring buttons and a SHIFT/ALPHA system for familiar operation. OnlineScientificCalc is built using Astro.js and Tailwind CSS v4, providing a responsive design. The project was launched on Product Hunt, and the creator is seeking feedback on its performance and user experience, especially from those in the tech community. This marks the creator's first completed project, with plans to create additional tools in the future.",
  "summary": "Why I built this Most free online calculators show math as flat text — 3/4 in one line, no real fraction rendering. That never felt right, especially compared to an actual physical calculator. So I built OnlineScientificCalc — a free scientific calculator with a proper natural display. Fractions, integrals, derivatives all render the way they would on a real calculator screen. Tech stack Built…",
