Hey everyone! 👋 I'm Kento, a solo developer from Japan. I built Foxden because I kept having ideas but never validating them. I'd think "someone probably already built this" and move on — without ever checking. Foxden fixes that. Type your idea, and AI instantly: • Scores it across 5 axes • Searches 7 sources for competitors • Estimates market size • Suggests improvements The first 3 ideas are completely free with no AI limits. I'd love your feedback — what features would make this more useful for your workflow? Try it: https://foxden-60v.pages.dev/en/...
