Smart toilets with AI gain momentum as digestive health tracker

Smart toilet technology using AI and optical sensors is becoming a mainstream health-tracking category. Throne Science, a startup cofounded by a WHOOP founder, raised $10 million in Series A to commercialize its AI camera system for analyzing stool consistency and urine color using gastroenterologist-trained models. TOTO launched Stool Scan in Japan with planned US availability in early 2027. Other companies like Vivoo, Kohler, and Withings are developing competing solutions. The sector has grown rapidly since 2023 due to advances in sensors, AI, and growing consumer attention to digestive health.
