Building Decision Trees with Arc AI

Building Decision Trees with Arc AI

In this LendAPI Academy session, you’ll see how Arc AI sits on top of your Agent Dashboard to design complex decision trees for you—no manual rule wiring required. Instead of dropping into individual applications and hand-coding underwriting criteria, you’ll watch Arc AI take a simple natural-language request for a three-layer rule for subprime personal loans and turn it into a fully built, publishable decision tree inside Rule Studio.
