Scientists have created a new artificial intelligence-powered app which could just save your life--by analysing your poo with a high degree of accuracy. Dieta Mobile asks users to upload photos of their business using their phones in order to have it categorised in line with the Bristol Stool Chart, a famous stool tool that helps doctors diagnose gut health and other health issues. According to the Bristol Stool Chart, healthy poo looks "like a sausage with cracks on its surface", or "like a smooth, soft sausage or snake." This is exactly the kind of poo Dieta Mobile is hoping to promote. The app's creators have just completed their first clinical trial of the app with promising results, suggesting that AI is better at categorising stools than humans.

Pimentel, who told Motherboard he had no financial stake in the app, said artificial intelligence takes the guesswork out of the diagnostic process, which generally relies on potentially inaccurate patient self-reporting. The study found that subjects appeared reluctant to use the full BSS, tending to gravitate toward the diarrhea (low) end of the scale. Investigators compared patients' self-reported scores and AI-generated scores with "gold standards" generated by two expert gastroenterologists. Scores calculated by AI aligned more closely with the expert scores, compared with patients' self-reported scores.
