Jev plays games.

What it does

Play chess or Connect Four against Jev, or spectate both sides while every legal move's probability remains visible.

How you can use it

Sketch your board game layout and write down how each player move looks as plain text. A developer can build an app that calculates all legal moves on each turn. The game sends this list and the current board layout to the model, which picks a move from the allowed choices.

Running computer turns requires a paid access key that connects the software to OpenRouter. Your app must enforce all rules and check winning lines itself. The model reads simple text rather than images of the board, and it makes casual choices rather than playing like a grandmaster.
