What is Sonist?
Sonist is built around markets that resolve on spoken words. Its workflow transcribes an audio source, identifies a configured keyword and routes a trade on a supported connected account. Public browsing is free; the live trading engine and advanced speaker controls are advertised in Plus and Pro plans that currently use a release waitlist.
