Where big-tech wins
They win on hardware integration: Echos, Nests, HomePods are tuned devices with far-field mics we can't match out of the box. They win on brand reach: your grandmother knows what "Alexa" is. They win on third-party skills: thousands of them. We don't pretend otherwise.
Where we win: trust, agency, and openness to your choice of model, provider, and hardware. If those matter, we are a real alternative.
