PrankGPT is a web service for phone pranks that uses a voice AI instead of a live caller. Enter the number you want to call, choose a voice, and write a text prompt—then the AI runs the call for you.
You pick from available voices, such as the villain-style Marv or the more modern, Gen Z-style Zephyr. After choosing a voice, you describe what the AI should say during the call—from light jokes to more structured prank scenarios.
PrankGPT is built on Vocode, an open-source library for creating voice LLM applications. Voices are provided via Rime Labs and Google Cloud to support natural-sounding speech and a stable calling experience.
PrankGPT fits anyone who wants to prank friends or coworkers with a realistic AI call without spending time rehearsing or preparing. You just need an idea for the prank and a few clicks in the web interface.
