Polywhisper

A Chrome Extension for real-time prediction market analysis.

Polywhisper listens to podcasts, videos, or any active tab, transcribes the audio in real-time, and uses Grok (xAI) to identify trending topics. It then instantly surfaces relevant Polymarket betting markets, allowing you to discover and track markets as they're being discussed.
