Knowster
The world quiz duel — everyone plays in their own language

Free, no ads — the only purchases are coins for characters.
Hi Product Hunt! Founder here.
Knowster started with a simple annoyance: quiz apps only ever match you with people who speak your language, so the "world" part never actually happens. Knowster matches you live with someone from another country — you both see the same question at the same second, each in your own language. Faster correct answer wins.
Every win counts for your country in a nations leaderboard with a new season every 3 months, so there is a running answer to "which country is actually the smartest?"
18,000+ questions fully playable in 10 languages (English, German, French, Spanish, Portuguese, Arabic, Turkish, Italian, Japanese, Russian), clan wars 5v5, and direct friend challenges to settle who is the smartest at the table. Free, no ads, no subscriptions — the only thing you can buy is coins for characters.
Would love honest feedback, especially from non-English speakers — the whole point is that nobody has to play in a foreign language. Happy to answer anything!
This is such a cool twist on trivia games. One thing I'd love is a post-round summary showing which questions I actually knew versus guessed on, broken down by topic. Knowing my weak spots would keep me coming back to improve, and it would give the game way more depth for serious players.
Played a round against someone from Germany and we both got stumped on a geography question about the Caspian Sea coastline. Love that the same question shows up in your own language at the exact same moment, makes it feel genuinely fair. The clan wars idea is clever too.
