Hey Product Hunt, I'm Colton. I built BetSlip Doctor. Here's the idea: before you place a bet slip, get a second opinion that shows its work. You snap the slip or type the legs. BSD checks each leg against up to 100 research questions in 10 groups (availability, lineups, recent results, exact-stat history, matchups, rest, venue and more). Every answer is tied to a source. The slip gets a score out of 100 (Value 30, Research 40, Slip construction 20, Stake fit 10) and one letter, A+ to F-. A few rules it never breaks: - No A unless your price is at or better than the market consensus. - Anything it can't check is marked Unavailable, never filled in. If the research can't finish, the Grade says Inconclusive. - It never places a bet, never holds your sportsbook password, never moves money. - A Grade is not a win probability. Sports are random. What else is in there: - **Doctor Fix:** on a D or F, the Doctor finds the fewest changes (3 max) that get you to B-. It never raises your stake or changes your book. - **Tail:** a free community where shared slips carry their Grade and records need 3 settled bets. No paid picks. - **History:** your real record across books, with sportsbook sync and CSV export. - **For AI people:** an MCP server, so Pro and Elite users can grade and track slips from Claude or ChatGPT. Your first Grade is free. LAUNCH25 takes 25% off your first month on the web; in the iPhone app use LAUNCH25 for Pro, LAUNCH25S for Starter, LAUNCH25E for Elite. What I want from you today: grade a slip and tell me the one thing that felt wrong. I'm here all day. 21+. Gambling problem? Call 1-800-GAMBLER.
