What makes Air.ai different
Air.ai is no longer offered: air.ai now serves an unrelated "Enterprise Readiness" company, and on March 24, 2026 the FTC announced a settlement banning Air AI and its owners from marketing business opportunities, with an $18 million judgment largely suspended (source: ftc.gov). Before that, Air.ai aimed to fully replace phone-based sales and support reps. It handles 10-40 minute conversations autonomously, pulling from knowledge bases and following multi-step workflows. Its pitch is replacing headcount, not augmenting agents.
