Hey Product Hunt 👋 I built CapnAI because I kept getting stuck on something stupidly simple: writing captions. Every time I wanted to post, I’d spend way too long thinking: “Is this caption good enough?” “Should I make it funny? Professional? Trendy?” So I built a tool that removes that friction. Now I just upload a photo → get multiple captions → pick one → done. CapnAI uses AI vision to understand the image and generate captions that actually fit the context, not just generic text. I’d love your feedback: What kind of captions do you struggle with most? What platforms should I improve next? - IOS: https://apps.apple.com/us/app/ca... - Android: https://play.google.com/store/ap... Thanks for checking it out 🙏
