ChatGPT Voice-Cloning

The Ultimate Prompt

Ever feel like ChatGPT just doesn’t get your style? You ask it to write like you, and it spits out something bland and generic. Super frustrating, right?

Well, I just stumbled upon an incredible post from an AI professional, Ruben Hassid, that tackles this head-on. The author has created one of the most detailed prompts I’ve ever seen for getting ChatGPT to perfectly replicate a personal writing style.

Austin Allison is familiar with using tech to disrupt real estate – his first venture, dotloop, was acquired for $120M. But despite bringing industry fame, one nagging regret remained. "I always wished we gave retail investors the chance to invest in dotloop and share that success," Allison later said. Now he’s doing just that. Austin built upon that experience to launch Pacaso, the co-ownership marketplace disrupting the $1.3T vacation home industry. And it’s working. They’ve surpassed $110M in gross profit to date, including 41% YoY growth last year. They’ve earned backing from firms like Maveron and Greycroft. They even reserved the Nasdaq ticker PCSO. And unlike dotloop, you can become an investor in Pacaso as a private company.

This is a paid advertisement for Pacaso’s Regulation A offering. Please read the offering circular at invest.pacaso.com. Reserving the ticker symbol is not a guarantee that the company will go public. Listing on the Nasdaq is subject to approvals. *partner’s advertisement

It’s not just a simple command. This thing is a full-blown system that turns the AI into an expert “voice-cloner.” I was blown away by the methodical approach!
