Just shipped my AI app for the Flowroom contest 🎉
Been building quietly for the past few weeks and finally ready to share. I submitted SnapCaption AI to the Flowroom AI App Creation Contest — and honestly, I learned way more than I expected during this build. 🚀 What it does You upload a photo → AI actually looks at it → and in ~10 seconds you get: - 3 platform-optimized captions - A 3-slide Instagram story - 30 ready-to-use hashtags Plus 5 tone styles: Funny, Heartfelt, Poetic, Gen-Z, Professional Works for IG, LinkedIn, Twitter. 🧠 The interesting part — Vision AI This isn’t a generic caption generator. The AI analyzes the actual image — scene, lighting, mood — not just keywords. But getting this right was tricky… - It would hallucinate random stuff (“midnight vibes” on a bright beach pic 😅) - Sometimes added irrelevant context like timestamps - Had to build a validation + retry layer to clean outputs 🛠️ Stack - Flowroom (app infra) - GPT-4o Vision (image + captions) - Vanilla JS - CSS animations Tried to make it feel like a real product, not just a demo. 💡 3 key learnings 1. Vision AI = prompt engineering gameIf your prompt isn’t tight, the output drifts fast. 2. UX matters more than AILoading states, copy buttons, history — spent more time here than on the model. 3. Shipping > perfectHad bugs till the last minute. Real-world fixes hit different vs sandbox builds. 🔗 Try it If you post content regularly, would love your feedback (especially on caption quality across different images) Link: https://flowroom.com/room/3SeEI4 Happy to answer anything about the build 👇
