I vibe-coded a full-stack AI product in 10 phases. Here's what actually happened

I want to talk honestly about vibe coding. Not to tear it down. Not to hype it up beyond recognition. I want to talk about it the way you'd talk to someone who just discovered something genuinely powerful and is about to sprint full speed without understanding the terrain. Because that's what I did. Mostly on purpose. And it taught me more about AI-assisted development — its real ceiling, its real floor, and the discipline it actually demands — than anything I'd read about it. Here's the project: Memtoon . The tagline is YOUR LIFE. YOUR STORY. YOUR WEBTOON. The pitch is this: you sign in with Google, connect your calendar, optionally upload a selfie, pick a timeframe (last 24 hours, last 7 days, or last 30 days), and in under two minutes your actual week becomes a personalised, manga-style webtoon comic. AI-written story arc. AI-rendered panels. A permanent shareable link. Zero creative effort required from you. I built the whole thing — ten phases, full-stack, production-deployed — us
