Most sportsbooks compete on odds and market depth. FanDuel is making a different bet: that the interface itself is a competitive advantage. AceAI, its conversational AI assistant, has completely reimagined the betting experience by letting customers research player and team stats, validate their picks, and build bets – all through natural conversation, without leaving the app.

Today, bettors typically bounce between stats sites, media platforms, and their sportsbook to research, compare, and place a bet. AceAI collapses that fragmented journey into a single in-app experience. An industry first when it launched in 2025, it enables customers to check stats, build and iterate on parlays – multi-leg bets spanning events or competitions – and confirm their reasoning through back-and-forth conversation. The tool returns structured bet suggestions that customers can refine as they go.

AceAI’s customer journey is deliberately intuitive. A user might start by asking Ace to compare two starting pitchers’ recent stats before an upcoming game or check how a team has performed against the spread over the past month.

That research flows naturally into action: a user who just pulled up the Dodgers’ stats might then ask AceAI to build a parlay around Shohei Ohtani hitting a home run in a game the Dodgers lose, adding a leg on the game going over on total runs. AceAI remembers the conversation as it unfolds, so follow-ups are seamless and personalized – users don’t have to start over each time.

“We’re seeing users go back and forth with Ace a lot,” says Rebecca Jee, Product Director at FanDuel. “They find it genuinely helpful and even when a response isn’t exactly what they meant, Ace can adapt. We often see that lead directly to users adding that bet to their slip.”

“A lot of users come to Ace before they’ve decided what to bet on,” says Jee. “They’ll ask about a player’s recent form or compare team stats, and that research is what gives them the confidence to commit. The stats and validation piece is just as important as the bet-building side – it’s what makes Ace feel like a real assistant, not just a shortcut to the bet slip.”

Importantly, customers stay in control. The tool surfaces information and options but only they can add selections to their bet slip. When a request is ambiguous, AceAI asks a clarifying question rather than guess. It is a deliberate approach: AI that informs rather than directs, giving customers confidence that the technology is working for them.

Accuracy is another non-negotiable aspect in a product that informs real-money decisions. AceAI draws player and team stats from structured data feeds like NumberFire, FanDuel’s analytics platform, rather than relying on the AI model to recall figures – eliminating a category of error that has undermined trust in some other consumer-facing AI products.
