What This Is

Sports betting markets are adversarial and most "expert" content is noise. The only inputs worth aggregating are where books disagree, how lines move, and what changed about the teams playing. Line Rally aggregates those three things, then asks one question most bettors never honestly answer.

Is the judgment doing the picking actually any good? The Calibration view (under Trends) tracks your Brier score and beat-market rate over every prediction you log. There's nowhere to hide — every estimate is recorded before the result, alongside the market's number. If the long-run scoreboard says the edge isn't real, then the edge isn't real, and the right move is to stop.

• Pick winners. The AI Brief returns facts only — injuries, weather, situational notes — because models asked to predict produce confident, plausible garbage.
• Recommend stake sizes without a tracked edge. Kelly only works if your probabilities are calibrated; the Calibration scoreboard is the prerequisite, not a side feature.
• Hide losing periods. Your scoreboard counts every resolved bet you've logged.

• Odds Board — every Maryland sportsbook side by side, with a bet slip locked to one book's prices.
• AI Brief — a fact dossier per game, saved for reopening.
• Research — every stat family for the NFL and FBS college football.
• Trends — line movement history and the calibration scoreboard.
• Portfolio — your tickets (logged or imported from screenshots) with P&L and exposure, private to your account.
