Would your gut have beaten the odds?
Hindsight lets you build rule-based sports prediction algorithms — no code, no ML — and backtest them against real historical games.
Free while in early access — no card, no catch.
Pick your stats
Choose the team stats you believe matter — goals, possession, special teams, anything in the data.
Weight your rules
Turn each stat into a bonus or penalty rule against the opponent, the league average, or your own threshold.
Backtest instantly
Run your algorithm over a full season of real games and see exactly how often it would have been right.
Your best algorithm deserves an audience
Make an algorithm public and it appears on your profile at hindsight/u/you — a shareable page with your track record behind it. Keep the secret sauce private; publish the ones worth bragging about.
Contests, trophies, bragging rights
Daily prediction contests against other builders — and the house — with badges and trophies on your profile to prove it. Or spin up a private contest and settle it with your friends: anyone with your invite link can see the matchup before they even sign up. See today's contests →
