PrankGPT

PrankGPT is an AI prank call generator that helps you create prank calls in minutes. Start by entering the phone number of the person you want to prank, then choose the voice you want the AI to use for the call.

You can select between Marv (the OG evil prankbot) and Zephyr (the gen Z queen). After choosing your voice, enter a prompt to instruct the AI on what to talk about—then hit “Start call!” to begin.

Under the hood, PrankGPT is built with Vocode, an open source library for building voice-based LLM apps. The voices used for calls are provided via Rime Labs and Google Cloud, giving you a quick way to generate voice interactions based on your prompt.

PrankGPT is a creator tool for anyone who wants to generate playful, voice-based prank conversations using AI. It’s currently set up for United States numbers in the call flow described on the tool.
