Hey Product Hunt! 👋 I'm Shubh, a solo builder from Maharashtra, India — built Zubhai
The problem I kept running into: every AI course teaches you theory. Nobody makes you actually USE AI.
Here's how Zubhai works:
→ AI interviews you for 3 minutes and builds your profile
→ You get a daily challenge built for YOUR exact job
→ You do it on ChatGPT (15-20 minutes)
→ Our AI agent reads your work and scores it 1-10
→ You earn points, build streaks, climb the leaderboard
Think LeetCode for AI skills. But for marketers, students, HR, teachers — not just developers. Works in Hindi, English, or your language.
Stack: FastAPI + Supabase + GPT-4o-mini + DeepSeek + Claude AI. All on free tiers.
Honest question for the PH community: what would make you actually open an app like this every single day? I read every comment 🙏
Congrats on the launch! I love the LeetCode framing for AI skills, that framing clicks immediately.
Curious how you handle the verification side, when someone submits a solution, is it another LLM checking the output or are you running actual execution/sandboxing? Asking because that tension between "did it work" vs "did it work the way a human would judge it" feels like the hardest part of this kind of product.
The "LeetCode for AI" framing immediately clicks because everyone knows what LeetCode did for coding interviews - it turned a vague skill into something measurable and practicable. Having a system that checks whether you actually achieved the desired outcome forces real understanding. How does the verification work in practice? AI outputs are non-deterministic - the same prompt can give different results. Are you evaluating the quality of the approach (the prompt strategy, the workflow) or the output itself?
