Introducing Bet Builder

We started Gambly to make betting as frictionless as possible: to get from idea to bet in a matter of seconds. We realized AI could power a lot of our ideas, so it made sense to start with chat to help people use natural language for bet discovery and odds comparisons.
We noticed many users already know what they want to bet–or who they’re looking to tail–and simply want to get straight to a fully loaded betslip as quickly as possible.
So we built GamblyBot.
Our new dedicated GamblyBot page uses AI to “read” your text, screenshots, or X links, then generates a one-click betslip to load all your desired bets directly onto sportsbooks. If Gambly Chat is our Google search, then GamblyBot is the “I’m Feeling Lucky” button.
But sometimes you don’t actually know exactly what you want to bet, or you have a general idea–a particular sport, matchup, team, player, bet type, and so on–but need a little help to finalize your betslip.
Gambly’s first premium tool, which we are launching free for a limited time, can help you build profitable betslips with the exact right bets for you as quickly as possible.
Introducing Bet Builder
The goal of Bet Builder is simple: list every bet for which we calculate edges and let you filter to find exactly what you’re looking for.
And in the spirit of getting you from idea to bet in seconds, we built it to be as mobile-friendly as possible.
Whether you’re…
- about to watch Monday Night Football and looking to bet an SGP,
- in front of your computer and want to do odds comp, or
- walking into the game and have 30 seconds to throw in some bets that are actually good
…Bet Builder is the first tool to finally provide real-time odds and highly accurate edges without the need for a complicated odds screen.
Why you can trust our edges
And as far as our edge calculations, I’ve written in the past about why you can trust Gambly’s edges.
I really can't emphasize enough the importance of properly comparing things like alt lines and derivatives. If you want to bet the over on Dak Prescott's passing yards, are you better off betting over 245.5 (-118) at Underdog or over 248.5 (-112) at DraftKings?
Even within a single sportsbook, you need to determine which alt lines are best. At DraftKings, there are currently 27 different milestone props for Prescott's passing yards alone. Maybe 260+ yards (+115) is best? Or is it 270+ yards (+143)? Or maybe it's actually 230+ yards (-176)?
The thing is, there's an answer to these questions, but it's a difficult one to uncover. We've put the resources into the data science behind these apples-to-oranges comparisons, so we know that if Prescott's median "true line" projection should be, say, 246 yards, then he has a certain knowable probability of going over 250 yards, 280 yards, and so on–based on a multitude of factors including historical range of outcomes, game specifics like the total and spread, etc.
The reality is that nearly every bet you make needs to be compared to other slightly different versions, and calculating which are best is an incredibly difficult task. We've put the time and energy into doing that–using real models built by pro bettors–which is what makes Gambly's edges unique. We're not treating 4.5-point and 5.5-point spreads the same. We're not treating over 243.5 yards as automatically better than over 247.5 yards just because the number is lower (it depends on the payout).
We're not just guessing.
The goal is to create a pro-level tool that anyone can use. We hope to distill all the complexities of what goes on behind the scenes into straightforward numbers shown in an extremely simple-to-use app.
We think it’s simple enough to just jump in and start using, so play around with Bet Builder while it’s free in beta, and shoot us any thoughts or recommendations to improve your experience.
Good luck in Week 3!
