What changed
A tenant calls at 9 p.m. In 2026, four AIs offer to answer. Three ship with a platform you buy first: Plexflow AI inside Plexflow, Yardi Virtuoso inside Yardi Voyager, EliseAI with EliseCRM, for large US operators.
Only one rents by the month, at a published price, on a free app, and answers French first, with no limit on calls or texts: Kasai’s Maintenance Agent.
