Call blocking algorithm

Call blocking algorithm

Unlike other services, Robokiller uses a predictive spam call blocking algorithm that proactively analyzes an incoming spam call before it rings your phone, and identifies whether it’s spam in less than a millisecond.

That means peace and quiet for you, because spam calls won’t even reach your phone.

Answer Bots

Choose your favorite Answer Bot voice — from Ice T and Kermit the Frog to Morgan Freeman — or even create your own. Then, share your favorite recordings and listen to other user-submitted recordings on RoboRadio.

Audio Fingerprinting

Audio fingerprinting

Our patented audio-fingerprinting technology is what makes RoboKiller so unique — and more effective than any other service on the market.

We create a record of a robocaller’s unique audio recording and check it in real-time against similar fingerprints in our global database. This means we can shut down any phone scam in seconds for all customers, even if scammers are spoofing their phone number.

We believe we have to address the root problem — the scammer behind the phone call — to effectively solve the robocall problem. We are the only solution doing this at scale.
