Prank Caller
The world’s first hyper-realistic AI prank calling platform.
What it does
After 10 years as the #1 prank app, we’ve reverse-engineered conversational flow to create the first hyper-realistic AI Prank Bot. Unlike our competitors using old-school recordings, our AI listens and adapts using custom details like names and locations. Join a global community of pranksters to share reactions and watch the "aha" moment live.

The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
