Hardware companies have realized that note-taking is one of the easiest AI use cases to build for, and consequently have been busy shoving mics into everything from pendants and rings to credit-card-sized pucks and wristbands. Still, despite the variety of devices, only a few companies have been able to stand out. One of these companies is Plaud, which has over 2.5 million people using its hardware or software. It is now launching a note-taker in a new form factor: earphones. Called Plaud One, these adopt the simple bare-bones style of Apple’s Airpods, and can record calls, while their case can be used to record in-person conversations or take notes.
