Who wins,and why.
AI-powered probability analysis on every major game. Track how predictions perform over time. See exactly where the model is sharp, and where it isn't.
Most prediction tools tell you who'll win. They don't tell you how often they're right.
Fourthsight is built on a simple idea: a prediction without a track record is just an opinion. We record every forecast we make. We measure accuracy by confidence band, by sport, by time. When the model is overconfident, we show it. When it's underconfident, we show that too.
Every major game, one terminal
NBA · NHL · MLB · Premier League · Champions League · Boxing title fights. Refreshed every 30 minutes.
The intangibles, surfaced
Recent form, injuries, rest, rivalry context, momentum. Generated on demand and grounded in current web data.
Track your own forecasts
Pick a side. We resolve it automatically when the game ends and feed it into your personal accuracy chart.
Honest about uncertainty
See exactly how often '80% predictions' actually win 80% of the time. The model gets sharper as data accumulates.
A prediction is made
For every scheduled game, an AI model produces a probability split. It accounts for form, lineup news, rest, matchup factors, and game-specific context like rivalry intensity or playoff stakes.
The game finishes
A background worker monitors scheduled games and resolves outcomes within minutes of the final whistle. There's no manual entry, no waiting, no edge cases.
Calibration updates
The actual result is compared to the predicted probability. Hit rates per confidence band are recomputed hourly. If 80%-confidence predictions have only hit 73% of the time, future ones get auto-adjusted.
Everything is visible
Every prediction. Every resolution. Every miss. Your accuracy timeline updates the moment a game ends. There is no hidden track record.
The chart that matters.
A model that says "80%" should be right 80% of the time. This is how we hold ourselves accountable.
Expected vs actual
Bars near the dotted target mean the model's confidence is honest. Bars below mean it's been overconfident — and we discount future predictions in that band accordingly.
Is this a betting app?
+
No. Fourthsight is an analytics tool. We do not facilitate wagering, accept bets, or partner with sportsbooks. We provide AI predictions for informational and entertainment purposes.
Will I make money using this?
+
We make no claims of financial outcomes. Past prediction accuracy is no guarantee of future results. Fourthsight is for understanding sports, not for financial decisions.
How is this different from existing tools?
+
Most prediction sites either hide their accuracy or only show their wins. Fourthsight logs every prediction we make — successful or not — and computes calibration in public.
What sports are covered?
+
NBA, NHL, MLB, English Premier League, UEFA Champions League, and major professional boxing matches. We'll expand based on which sports our users actually engage with.
Is it really free?
+
The core product is free while we're early. We may introduce a paid tier with higher-frequency analysis and longer history retention. Existing users keep their accuracy history regardless.
