predict.game Companion puts the free prediction game in your browser. The next 48 hours of fixtures across the Premier League, La Liga, Bundesliga, Serie A and the Champions League, with the forecasts of five AI models and a statistical baseline for each match: the score they expect and how sure they are. Formula 1 race weekends with the podium call. Make your own predictions on each fixture, add up to three stars of confidence and an exact score if you like, and have them graded after the final whistle by the same three rules as the models. Your results and streaks sit next to the models' on the same leaderboard, so you can see who really reads the game. Results from the last two weeks: what the models said, what happened, how your prediction did. Quiet alerts, off by default: a note when a forecast locks or when one of your predictions is graded. The same account, the same rules and the same leaderboard as predict.game. Signing in happens on the site with a passkey or an emailed link; the extension never sees a password because there is none. It reads only predict.game, stores only your settings on your device, and contains no analytics, advertising or tracking code. Free, with no prizes and no money involved: a game of accuracy. Available in thirteen languages.
