OddsProbe is a free collection of sports betting analysis tools for serious bettors in the US, UK and Canada. It includes an AI analyst powered by Google Gemini, an EV calculator, Kelly Criterion bet sizing, and a parlay calculator.

Is OddsProbe really free?

Yes. All tools are completely free. The AI analyst uses Google Gemini's free tier — you just need a free Google account to get an API key. No credit card is ever required.

Does OddsProbe sell betting picks?

No. OddsProbe is a research tool, not a tipster service. We give bettors better analysis and math to make their own informed decisions. We never sell picks or guaranteed outcomes.

About OddsProbe

Why We Built This

Most betting "tools" online are either pick-selling operations dressed up as analytics platforms, or unnecessarily complex $50/month subscriptions for calculations you could do yourself. OddsProbe was built because serious bettors in the US, UK, and Canada deserve free, accurate, and honest tools that respect their intelligence.

We don't sell picks. We don't run a tipster service. We don't promise winning records. We give you the AI analysis and the math to make better-informed decisions yourself.

Our Principles

Always free. Core tools are free forever. We earn through transparent advertising and clearly-disclosed affiliate partnerships.
Your data stays yours. All EV and Kelly calculations run in your browser. We never collect your bankroll figures or betting data.
Math first. Every result uses established formulas — Kelly Criterion, expected value, implied probability theory. No proprietary black boxes.
No picks, no guarantees. We are a research tool. We will never sell you a "lock" or promise profitable outcomes. Sports betting involves real financial risk.

The AI: Google Gemini 2.5 Flash

As of March 2026, OddsProbe uses Google Gemini 2.5 Flash for the AI analyst. This is Google's current fast, capable model available on their free tier — 1,500 requests per day with no credit card required. You provide your own free API key from aistudio.google.com, which means your conversation history goes directly to Google's servers under your account, never through ours.
