Hi Product Hunt community! 👋 I'm Takahiro, the founder of HOWAI. First, a quick note: Currently, the platform is optimized for the Japanese market, and the main app is in Japanese. However, we’ve created an English landing page (howai.vercel.app/en) to share our vision with the global community. We are here today because we want to know: Does this concept resonate with you? The Problem: AI is evolving too fast: Everyday users are struggling to keep up with the constant updates (Model Drift). Information is scattered: Great prompts are buried in endless SNS feeds, making them nearly impossible to find or reuse effectively. The Solution: HOWAI — The "Cookpad" for AI. In Japan, we have a unique culture called "Cookpad," where millions share and refine recipes to make life better. We realized the AI world needs exactly the same thing: a centralized, "living knowledge base." We don’t just share prompts; we guarantee their reliability through our unique "Reproducibility Cards" that specify the exact model and parameters used. Our Goal: To turn "I don't know how to use AI" into "I have the perfect recipe for that." We want to see if this "Cookpad model" for AI is something the global community would find valuable. I’d love to hear your feedback, thoughts, and whether you'd like to see a global version of HOWAI! Thank you for your support!
