Ever wondered which coworker secretly raises your blood pressure?
One developer decided to find out. He used Claude Fable 5 to pull heart rate data from his WHOOP tracker, then matched stress spikes with meetings on his calendar.
What he got was a surprisingly detailed ranking of coworkers based on which meetings seemed to stress him out the most.
It's a funny experiment, but it also shows how easy it has become to build highly personalized tools with AI. A project like this would've been a headache not long ago. Now it's the kind of thing someone can put together over a weekend.
