Spam blocking effectiveness: Robokiller states its technology is 99% effective at stopping spam calls.
AI call analysis: Its predictive call-blocking algorithm analyzes call metadata in less than a millisecond and blocks calls identified as spam before they reach the phone.
Audio fingerprinting: Patented audio fingerprinting compares robocall recordings in real time against a database containing more than 1.5 billion processed phone numbers and millions of audio fingerprints.
Answer Bots: Answer Bots answer spam calls with prerecorded messages intended to waste spammers’ time.
Spam texts: Robokiller filters SMS and MMS using block/allow lists, number reputation, and content analysis; it states that messages are never stored or shared.

Enterprise integrations: Robokiller offers business integrations with SIP and HTTP options and public- or private-cloud deployment.
Enterprise coverage: Robokiller Enterprise says it blocks threats on mobile, landlines, and text using predictive AI and audio fingerprinting.
