The new transparency tool overlays real-time odds comparisons directly on sportsbook pages, helping users spot better prices without switching tabs, paying for pro dashboards, or opening another betting account.
San Diego, CA (PinionNewswire) — OddsGuard, an AI-based betting technology company, today announced the launch of its flagship odds-comparison browser extension: a free, privacy-first overlay that helps sports bettors compare prices across sportsbooks while browsing the sites they already use.
For years, serious bettors have relied on “line shopping” — checking multiple sportsbooks before placing a wager — to avoid taking a worse price than the market offers. But in practice, line shopping remains slow and fragmented. Users often jump between sportsbook apps, browser tabs, odds screens, spreadsheets, and paid dashboards while live prices move in real time.
OddsGuard is designed to remove that friction.
The extension runs in the background on supported sportsbook websites and displays real-time price comparisons from 77 of the largest sportsbooks directly on the page, seamlessly matching across sporting events, markets, and outcomes. When a user views a market, OddsGuard instantly displays an overlay above the market outcome, whether the user is looking at the best price, a better price is available elsewhere, highlights potential +EV opportunities, and provides comparison context without the user ever having to leave the sportsbook page they are already browsing. With one click, they can be transported to the better-priced market opportunity.
“Sports bettors have been trained to act like human aggregators — checking ten tabs, refreshing odds screens, and trying to move faster than the market,” said Jonathan Friedlander, CEO of OddsGuard. “OddsGuard turns that workflow into a simple overlay. It is like Honey at checkout, but for betting lines: when a better price exists, we show it where the decision is already happening.”
OddsGuard compares real-time prices from 77+ industry-leading sportsbooks, supports instant overlay analysis on 39+ of those sites, with new sites added weekly, all to ensure consumers don’t leave money on the table. The product is always free and privacy-first with no registration required.
Leveling The Playing Field
Professional-grade odds tools can cost $700 per month and often require users to monitorseparate dashboards. OddsGuard’s thesis is that price transparency should be a vailable to everybody all the time, not locked behind expensive software for professional use only.
“Most people understand comparison shopping when they book a flight, buy insurance, or use a coupon extension,” Friedlander added. “But sports betting still has an information gap. Two books can show meaningfully different prices on the same outcome, and many users never see the better number. OddsGuard exists to close that gap.”

Not a Sportsbook — A Transparency Layer
OddsGuard is not a gambling operator. It does not accept wagers, hold user balances, process betting payments, or settle bets. Instead, the company positions itself as “Expedia or NerdWallet, but for sports entertainment.”
“OddsGuard does not tell people what to bet, and we do not place bets for anyone,” Friedlander said. “We show pricing information more efficiently. The user stays in control, the sportsbook remains the transaction venue, and OddsGuard provides the missing comparison layer.”
