I got tired of AI hype so I built something to cut through it 👋

Hey Product Hunt

I'm Harsh, solo founder from India and honestly just a guy who got really frustrated with AI benchmarks.

Every week a new model would drop claiming to be #1 on some leaderboard I'd never heard of. So I'd actually go test it. Open two tabs, paste the same prompt, compare outputs manually like some kind of unhinged AI scientist.

What prompt would you use to truly test an AI model?

We built DualMind Arena so humans can judge AI models blindly instead of trusting benchmark leaderboards.

But we need your help.

What is the single hardest or most interesting prompt you would throw at two AI models to really expose which one is better? Could be a coding challenge, a creative brief, a logic puzzle, a debate topic anything.

DualMind Arena - Where AI models battle and humans decide the winner

AI comparisons are biased, slow, or buried in benchmarks. DualMind Arena stages real-time head-to-head battles between top AI models. One prompt. Two responses. No brand names shown. Humans vote for the better answer. Discover which model actually performs best in creativity, logic, and reasoning — based on real user judgment, not marketing claims.
