The bookkeeps thescore.

Chalkbook turns a camera roll of bet slips into a graded, auditable ledger — every stake, every leg, every payout — and tells you where your edge actually lives.

From slip to settled

Snap the slip

Upload a screenshot from your book. Claude Vision reads the stake, the legs, the lines, the odds — you review, correct anything, confirm. Nothing enters the book unreviewed.

The book grades itself

Every hour the settlement job pulls final scores and grades what finished — moneylines, spreads, totals, alt lines, teasers. Pushes recompute parlays the way the book would.
