To slow the rise of homelessness, one program in Los Angeles County has been using artificial intelligence to find and offer help to people before they lose their housing.

The program has shown promise at preventing homelessness. But first, outreach workers need to convince people the help they’re offering isn’t a scam.

“We hear all the time from our clients that our program sounds too good to be true — what’s the catch?” said Dana Vanderford, head of the Homelessness Prevention Unit run by the L.A. County Department of Health Services.
