The MeThinks suite
So you think
you know it. Prove it.
Mariana Ventures makes mastery-based trivia apps. Five real levels, real questions, and an honest score at the end — no padding, no shortcuts.
Free to play. Ad-supported. Built by a small team that actually writes every question.
The lineup
Two apps live, more on the way
Each MeThinks app is its own subject, its own question bank, and its own five-level climb.
MeThinks I Know History
Available now
From ancient empires to the modern world. Fifteen questions a round, real explanations when you miss one, and a daily challenge that resets at midnight.
MeThinks I Know AI
Available now
The people, breakthroughs, and arguments that built modern AI — from the 1956 Dartmouth workshop to the Transformer paper.
Why MeThinks
Built to teach, not just to score
Real progression
Five levels, 70% to advance. Pass one and the next unlocks — for good. No level ever locks back up on you.
Hints and explanations
Stuck? Five hints a round. Get one wrong, and we tell you why — right there, before the next question.
A daily habit
One mixed-question challenge a day, same set for everyone. Miss a day, the streak resets. No mercy, no make-ups.
Pick a level. Find out what you actually know.
