Can you beat the AI?
Three drills, three formats. Nothing to sign up for.
AI helps after you think, never instead.
- 01
Think first
Each drill takes a minute or two. You answer on your own, with no AI to lean on.
- 02
Get scored on reasoning
Estimates are scored by how close you got, confidence bets by how well calibrated you were. Not just right or wrong.
- 03
Watch your rating climb
Every skill has a chess-style rating. Keep a streak, climb the weekly league, and see yourself get sharper.

The crow who drops stones
In Aesop's fable, a thirsty crow finds a pitcher with the water too low to reach. Nobody hands it a straw. It drops in pebble after pebble until the water rises. Real crows and their relatives, the rooks, solve this exact puzzle in lab tests.
Vero is named after the Latin verus, “true”. It cheers when you catch the AI out and raises an eyebrow when you take its word for it.
