AI · 28 Years of Probability Models · Try Free
I built betting models for 28 years. Then I taught everything to an AI.
Type a matchup, odds, or bet you’re considering. The AI Betting Assistant helps you compare the market price to a fair price — with probabilities, edge estimates, and VALUE/PASS verdicts.


Built by Underdog Chance. No picks hype. No guaranteed wins. Just probability, price, and disciplines.
Most “AI betting tools” are just chatbots with betting language.
They sound confident. They mention injuries, trends, and recent form. But without a pricing framework behind the answer, it is still mostly a guess in fluent English.
Underdog Chance is different. I’ve been building sports betting models since the early 2000s and pricing bets since 1998. The Assistant is built around that same value-betting logic: estimate a fair price, compare it to the market, and decide if the number is worth betting.
Four tools. One smarter betting workflow.
The Board
Your daily dashboard for MLB, NBA, and NHL. See UC Fair Lines, market snapshots, estimated edge, and VALUE/PASS verdicts in one place.
Betting Analyst
Type a matchup, odds, or bet. The Assistant checks the price, applies the Underdog Chance probability framework, and explains the verdict in simple language.
Learn Betting with AI
Unlimited chat with AI Betting Assistant. Learn betting and do it correctly.
My Bets Tracker
Track every wager, measure ROI by sport and bet type, and see whether your decisions are actually producing long-term value.
How the AI Betting Assistant actually works.
1) Ask for any game on demand
Type any matchup, market, or betting idea you want analyzed. The Assistant performs a full on-demand analysis for that exact request, using real token-based research to gather context, review stats, and apply my betting framework.
2) Your odds become the key input
Serious betting starts with the price. You enter the odds you have, and the Assistant compares them to its estimated probabilities to decide whether the bet is VALUE or PASS. No fake confidence. No blind picks. Just a structured betting decision based on price.
3) You also get my handmade Board
As a bonus, the app includes the Board — my own founder-made lines and pricing ideas. It’s an extra layer of value that makes this different from generic AI tools. When I see a market or season worth pricing, I can add it there.
4) It helps you become a better bettor
The app is not just for analysis. You can also use the chat to learn betting basics, probability, and value, and use the simple bet tracker to monitor your wagers and results over time.

Why this isn’t another AI betting wrapper.
Built by one person who still models sports.

I’m Marjan. I placed my first bet in 1998 — not because I loved sports, but because I loved math.
I started building the MLB model in 2004, and that logic still sits underneath the app today. Underdog Chance has been my full-time work since 2015.
Over the years, the YouTube channel, the Masterclass, and the spreadsheet models have helped serious bettors learn how to think in probabilities instead of opinions. Some built their own models. Some went on to work in the industry. The framework works. The AI simply makes it faster and easier to use.
If something in the app is wrong, you hear back from me — not a faceless support team.

FAQ
How is this different from ChatGPT or other AI betting tools?
Most AI betting tools are just language models dressed up as betting products. They generate text. This works differently. The Underdog Chance Assistant is built around my own probability framework, with model-backed coverage where the data is strongest. The AI’s job is to communicate the logic clearly — not to invent edges.
What sports does it cover?
The Board covers MLB, NBA, and NHL with daily fair lines. The Assistant can analyze many other sports and markets you paste in, including NFL, college sports, soccer, tennis, esports, and more.
How accurate are the models?
No model is right every night. The edge comes from identifying mispriced bets over a large sample, not from trying to predict every single game perfectly. This is probability work, not magic.
Is this a picks service?
No. It gives you fair lines, edge percentages, and VALUE or PASS verdicts, but you make the final decision. The goal is to help you think like a bettor who understands price.
Can I see how it works before subscribing?
Yes. Visit the app to see the workflow and current access options.
Can I see the underlying models?
Yes. I also sell spreadsheet models separately for bettors who want to run the numbers themselves, and the Masterclass teaches the thinking behind them.
