Spot a peach among the fruit, point at Egypt on a map, or solve a chess picture. Jev Cards gives you and a vision model the same cards, then compares your answers and speed.

José Sabater at Opper built it with Claude Code and vision-model tools. Play solo, chase a streak, or invite friends into a live match with Jev as another player. It is free to try, and the code is open.

The fast answer is not always the right one.
