👋 Hi Product Hunt! I'm excited to launch **MathCast**, a Chrome extension designed to make mathematical notation easier to find and use. While reading papers, writing LaTeX, or studying technical content, I often spent too much time searching for symbols like ∂, Σ, λ, or complex notation. MathCast makes this process instant: 📐 Search 566+ math symbols 🔍 Find symbols by name, meaning, LaTeX, or category 📄 Works with web pages and PDFs ✨ Preview formulas before copying 🌎 Supports Korean, English, and Japanese The goal is simple: reduce the friction between understanding mathematics and writing it. I’d love to hear your feedback and suggestions for new symbols or features!
