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.

Show your work

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.
