Parlay Builder is a free AI parlay builder for NBA, NFL, MLB and WNBA. Ask the AI for a parlay or browse tonight’s board — every pick arrives with its measured hit rate, the games behind it, and its expected value against live sportsbook odds.
Browsing is free and needs no account. The AI parlay generator is free to use with a daily allowance, so you can build a ticket and check the numbers behind it before you decide whether a paid plan is worth it.
Yes. You can open the board, generate a parlay with the AI and see every leg’s hit rate and expected value without paying and without creating an account. Paid plans raise the daily limit on AI requests and unlock deeper analysis, but the free tier is a working product, not a preview.
Yes. Browsing tonight’s board and viewing prop hit rates needs no signup at all. Creating a free account only adds a higher daily allowance for AI parlay generation and lets you save bets to track them later.
Every prop on the board is scored on measured history rather than opinion: how often the player has cleared that line recently and across the season, how the line compares to the implied probability in the current odds, and how consistent the underlying games have been. When you ask for a parlay, the generator searches that scored board for the combination that best fits your leg count, risk level and target payout — so each leg arrives with the games behind it attached.
The full prop board across NBA, NFL, MLB and WNBA, historical hit rates, live odds comparison, and a daily allowance of AI parlay generations and prop analyses. Paid plans raise those allowances and add deeper trend and correlation tooling.
No — and any tool that claims otherwise is lying to you. Parlay Builder is a research tool. It surfaces bets where the measured probability looks better than the price, which is how you win over the long run, but every individual bet can lose. Bet responsibly; if gambling stops being fun, call 1-800-GAMBLER.
NBA, NFL, MLB and WNBA, for both player props and team markets, with odds compared across the major US sportsbooks so you can line-shop before you bet.
