Hey HN,
I built PolyTell, a Chrome extension that uses AI to analyze news articles and tweets in real time, then surfaces relevant Polymarket prediction market odds directly inside the page — no tab switching required.
How it works:
Visit any news site or scroll your X/Twitter feed
PolyTell's AI reads the content, extracts key events, and matches them against live Polymarket markets
Inline cards appear right below the relevant content showing the market question, current odds, and a one-click bet button
For example, if you're reading an article about tariff policy changes, PolyTell will automatically find the matching Polymarket contract and show you the current price — all without leaving the page.
It supports both English and Chinese, and works with infinite-scroll feeds like X. In the demo video below, you can see it analyzing a news article (5 events matched), then switching to the X timeline where it picks up 10 events and generates 10 bet recommendations across tech, politics, and business categories.
