More workers feeling anxious, stressed or blue have a new place to go for mental-health help: a digital app.

Chatbots that hold therapist-like conversations and wellness apps that deliver depression and other diagnoses or identify people at risk of self-harm are snowballing across employers’ healthcare benefits. About a third of U.S. employers offer a "digital therapeutic" for mental-health support, according to a survey of 457 companies this past summer by professional services company WTW. An additional 15% of the companies were considering adding such an offering in 2024 or 2025.
