Imagine you're on a betting site watching live odds.
You click the extension โ a floating calculator appears.
You enter odds from two bookmakers.
The tool tells you:
- Whether arbitrage is possible
- How much to stake on each side
- Which team has better winning chances via AI
All within the same tab. No switching apps. No guesswork. Just clarity.
Instead of building a separate website, this tool runs directly on betting platforms through a Chrome Extension:
- Injects a floating calculator into the right side of any webpage
- Offers immediate, context-aware analysis without switching tabs
- Built for speed, simplicity, and real-time execution โ exactly where decisions are made
- Uses HTML, CSS, JavaScript โ completely frontend-based
- Injects via Chrome Extension APIs (Manifest V3)
- AI features powered via DeepSeek/OpenAI APIs
- Output rendering via
marked.js(clean markdown parser) - No backend, no hosting, no delays
