Most football "tipster" sites have the same trick: they show you the winners and quietly bury the losers. I wanted to build the opposite — an AI that commits to a prediction before a match starts, logs it, and then shows you whether it was right or wrong. No cherry-picking, no editing history after the fact.
That tool is now live as Odds Radar Pro. Here's how it works under the hood, and the design decisions that took the longest to get right.
The core idea: don't trust the market, measure against it
A bookmaker's odds are basically a probability with a profit margin baked in. The naive approach is to copy the market and shave the margin. I went the other way.
The AI builds its own probability for every match — home win, draw, away win, over/under 2.5 goals, both teams to score — from real signals: recent form, goals scored and conceded, head-to-head history, key players, injuries, lineups. Only after it has its own number does it look at the market. The gap between the two is the whole product: that's where a game is mispriced, and that's where value lives.
