I'm a finance professional by career, but I've always loved books. Over the past few weeks, I challenged myself to build something completely outside my comfort zone using vibe coding—and that's how was born. BookRice is a platform that helps readers discover books while giving authors a simple way to promote their work. It's still in its early days, and I'm improving it every day based on real user feedback. I'd genuinely love your honest thoughts. Don't hold back—if something is confusing, broken, unnecessary, or could be much better, please tell me. Constructive criticism is far more valuable than compliments at this stage. Take a look at and let me know: • What's your first impression? • Would you use it? • What would make you come back? Your feedback will help shape the next version. Thank you!
