Even smart toothbrushes have AI now

Before the likes of Oral-B started selling Bluetooth-enabled, app-connected toothbrushes, there was Kolibree. The startup developed one of the first "smart" toothbrushes that incentivized regular brushing and documented oral hygiene habits. We caught the first Kolibree brush at CES several years ago ahead of its successful Kickstarter campaign, and this year the company is back at the tech show with a new model: the Ara. "Patented deep learning algorithms are embedded directly inside the toothbrush on a low-power processor," Kolibree's press release reads. One of the benefits of this new chip is you don't need the companion app open on your mobile for brushing data to be recorded.
