These act for themselves, under their own terms, and only when you use them: Apple Health and iPhone speech recognition on your own phone; the YouTube player when you press play on an exercise video; the maker of your browser for speech to text in Chrome; Open Food Facts, which your phone asks when you scan a barcode; and an AI you connect yourself.
