How it works
Screenshot → Grade → Tail
01
Screenshot
Snap your bet slip from any sportsbook. We read the legs, odds, and stake — no typing.
02
Grade
The model de-vigs every leg, adjusts for correlation, and stamps an honest A+ to F with the why.
03
Tail
Share the stamp, climb the board, or tail the sharps whose A-grades keep cashing.
The toolkit
Everything between you and a bad slip
The Grader
Screenshot any slip. The model prices every leg against the market, flags dead money, and stamps it A+ to F — with the reasoning.
Public Ledger
Every grade we publish is tracked and settled on the record. Calibration, hit rates, ROI by band. Trust, but verify — we dare you.
Tail Alerts
Follow sharps whose grades actually cash. Get pinged the moment a verified A-grade slip drops.
Live Prop Chat
Ask about any prop in plain English. Lines, matchup context, and the model's read, mid-game.
Leaderboards
Weekly boards for ROI, biggest hit, and streaks — settled slips only, no screenshots-of-screenshots.
Correlation Engine
Same-game legs aren't independent. We estimate true joint probability instead of naive multiplication — the whole ballgame for SGPs.
Pricing
Free to start. Sharp when it counts.
Final pricing lands with launch — join the waitlist and you’ll lock founder pricing forever.
