Sonist automates live mention-market trading on Kalshi and Polymarket. It brings markets from both exchanges into one interface and monitors live audio, subtitle feeds, or accessibility captions for configured words. When a word is said, Sonist applies your risk limits and sends the trade through your account, letting you use the lowest-latency source available for each event.
Hey Product Hunt, I built Sonist because live mention markets move on a single spoken word and ordinary video or transcript feeds can arrive too late.
Sonist combines Kalshi and Polymarket markets with live audio, subtitle, and accessibility caption sources, then applies your configured risk limits before placing an IOC order through your own account. I focused on committed-word matching so a mention can trigger quickly without being counted twice.
I would love feedback on source selection, speaker gating, and the session view.
