Hey Product Hunt 👋 I'm Johnny - solo founder of Knowza.ai and the person behind the Johnny Chivers AWS YouTube channel. Here's why I built this: I've hosted AWS certification practice exams on Udemy for a while, but the format always frustrated me. Static question banks, no adaptability, no real explanation of why an answer is right or wrong. I had no control over the experience, and frankly neither did the learner. I wanted something I owned - with dynamic, AI-generated questions based on how I write exam content that adapt to what you're weak on. And an AI assistant that actually helps understand the decisions behind each answer, not just memorise options. So I built Knowza on AWS Bedrock (Claude), Next.js, Amplify, and DynamoDB. Dog-fooding the stack I teach felt right. Some may view this as just another exam webside coded with the help of AI - but I already operate in the domain space and provide exam revision content. The introduction of Agentic AI has afforded me the ability to take what I was already doing with third partys and "bring it in house". Having the time to build the platform no longer became the blocker. Would love to hear from you: - Which AWS cert are you working toward? - What's been the hardest part of your prep? - What's missing from the tools you've tried? Free tier available — no card needed. Dive in and all feedback goes straight to the roadmap. 🚀
