Sonist

Sonist is automated live mention-market trading software for Kalshi and Polymarket. It turns live audio into trades on your own account. You choose a live source, select the market options you want to trade, and configure the words that should trigger each order. Sonist can monitor live audio, subtitle feeds, and accessibility captions, so the best available source can be used for each event. When a configured word is committed in the transcript, Sonist checks the strategy and risk limits before sending an immediate-or-cancel order through your connected exchange account. The web interface brings markets from both exchanges into one place. During a live session, it shows the transcript, keyword hits, signals, skipped orders, fills, positions, and session P&L. Traders can see both what happened and why Sonist traded or refused a trade. Price ceilings, position limits, exposure caps, a kill switch, and panic-sell controls keep each session within the limits set by the account owner. Sonist is designed for mention markets where speed and a clear audit trail matter. Free accounts can browse approved markets and follow live market data. Demo access is available by approval, while paid trading plans are being prepared for public release.
