Overview

PrankGPT is a web-based voice calling tool that asks for a target phone number, a voice choice, and a prompt before starting a call. The homepage positions it as an AI-powered prank caller rather than a general-purpose chat app.

The product’s main workflow is narrow and direct: choose who to call, decide which voice should speak, and describe what the AI should talk about. The site also credits Vocode as the open source voice-app framework and mentions voice providers from Rime Labs and Google Cloud.

Features

Phone-number targeting

Users start by entering the phone number of the person they want to prank, indicating the product is built around placing a voice call to a chosen number.

Voice selection

The flow lets users select between at least two named voices, giving them a simple way to change the caller persona.

Prompt-based call instructions

A free-text prompt field lets the user tell the AI what to talk about during the call, which shapes the conversation topic or script.

Region selector

The page includes a country selector set to United States, suggesting the call flow is organized around a phone region or locale.

Voice-tech dependencies

The site notes that it is built with Vocode and uses voices provided by Rime Labs and Google Cloud, which clarifies some of the underlying voice stack.

Use Cases

Triggered prank calls
Someone can enter a phone number and a prompt to generate a prank-style AI call with a chosen voice persona.
Prompted call experiments
A user who wants to test how a scripted call sounds can use the prompt field and voice selector to shape the conversation.
Voice persona testing
A visitor comparing voice options can switch between Marv and Zephyr to see how different personas affect the call.
