The program offers participants financial assistance if they can’t afford bail, creates an “intelligent calendar” to help them fulfill court-mandated obligations (like court appearances and drug tests), and provides in-person support for job training, counseling, housing and more.

“We are increasingly alarmed by the injustice in our criminal justice system,” JAY-Z said in a statement. “Money, time and lives are wasted with the current policies. It’s time for an innovative and progressive technology that offers sustainable solutions to tough problems. Promise’s team, led by Phaedra, is building an app that can help provide ‘liberty and justice for all’ to millions.”

Promise will be unveiled at Y Combinator Demo Day on March 20, though a public release date has yet to be announced.
