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.
@nathan_reuter thanks for your suppor and ya that the hardest part but it doesnot work like this how it work is is see your actual output using playwright then there are 3 to 4 models that debate about it then you get your result point and every thing

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?
Hey Product Hunt, We recently opened up Zubhai.com to early users. We got signups, but here is the brutal truth: Almost everyone leaves after 2 or 3 days and never comes back.
As a founder, I’m blind to my own mistakes. I need the brilliant product minds here to tear us apart.
Is our onboarding too confusing?
Is the value proposition missing?
Does it feel like a tool you’d only use once?
Please check out Zubhai.com and give us your most brutal, unfiltered feedback. Don't be polite. Tell us exactly why you would close the tab and never return."
