Stop typing. Start speaking. 4x faster.

Hello Product Hunt! 👋 I’m the maker of RichFlow. I'm excited to share this project with you all today! As an investor, I often used financial calculators, but I found most of them were just boring tables of numbers. I wanted to visualize the trajectory of wealth, not just read a static list. So I built RichFlow with a focus on Visualization and Speed (built with TypeScript). Key tools included: • 📈 Compound Interest: See how your daily "coffee money" grows over 10 years. • ⚖️ Kelly Criterion: A tool for finding the optimal investment size to avoid ruin (my personal favorite!). • 🌍 Global Ready: Supports 7 languages including English, Spanish, Japanese, and Korean. It's 100% free, no login required, and supports Dark Mode. 🙏 I'd love your feedback: Is there any other specific financial calculator or indicator you use often? I'm planning to add more tools based on your suggestions! Thanks for checking it out! 🚀
