Both detect answering machines. AMDY is a standalone, telco-agnostic AMD gateway built for predictive dialers — 30–75× cheaper per detection, with honeypot intel Twilio doesn’t offer, and no need to move your calls onto anyone’s platform.
If you already run all your voice traffic on Twilio and only need a basic human/machine flag at low volume, Twilio’s built-in machine_detection is convenient — it’s one parameter on a call you’re already paying for. AMDY is the better fit when you run a Vicidial / predictive-dialing operation, push real volume, care about cost per detection, want honeypot and carrier-pattern intelligence, or don’t want to re-platform your telephony.
50,000 detections / month on the Sandbox plan, no card. Install on your Vicidial server in about 5 minutes and compare the numbers yourself.
