Every US thoroughbred track running on any given day — roughly 25-30 race cards, including Aqueduct, Belmont, Churchill, Santa Anita, Gulfstream, Saratoga, and the regional circuits.

Derbee is an analytical research and educational tool for horse racing enthusiasts. We use machine-learning models to identify the top selection and best-value pick on every race, and we coach you on patterns in your own analysis history. We are an information service, not a brokerage.

We tested our models on 5 full years of races they had never seen during training. The top-pick model identified the winner 6 percentage points more often than the public favorite. The best-value model returned +21% on the picks it flagged. Full results on the proof page.

If you log 10+ picks a week, yes. Below that, Sam will still write you a brief, but the patterns Sam spots need a meaningful sample of your own selections to be specific to you.

Yes — $9 buys you one race card. That's a real day of the product.

Race Card: sales final, but we auto-refund if a card is cancelled. Monthly: 7-day full refund window. Annual: 14-day full refund window. Cancel any time from Settings.

Automatic refund the next morning. No support ticket needed.
