PlayFellow Co-op

PlayFellow Co-op is an open-source AI buddy for adult PC gamers whose hands can't keep up with what a game demands: one-handed play, tremor, RSI, fatigue. You play. When a part is too hard, you say what you want, in English or Arabic, by voice or by typing ("grab the coins on the left", "get me past this jump"). The buddy plays that part with the same keys you would press, only in the game window you chose, and then gives the controls back. F9 hands the controls over and back; F12 stops everything at once; split controls keep chosen keys yours, so the buddy can never press them. Every key is checked against the game's controls card before it is pressed: 0 breaches in every run that counts them. In co-op tests it finished 65 of 66 asked-for parts, and in the real SuperTuxKart window it finished 1st on Novice twice. It also pushes the frontier of embodied agents: a model that turns a spoken request and a marked picture into safe game keys, live. Alone on raw pixels the model won 0 of 28 games; choosing local skills it won 15 of 15, for about a quarter of a cent a win with open weights, and it can write new skills that run in a sandbox and must beat the old ones before use. Every number comes from a result file in the repo, and every test runs offline.
