I built a product that allows you to train GPT on your writing style. Here's how it works. So since I'm a startup founder, I have to send a lot of investor cold emails. So I'm building a model called investor reach out cold email. So I'm prompting it to act as a startup founder named Justin. I'm telling it that it will receive a recipient's name and the investor's background info. And I'm telling it that it will draft up an email to book a call with this investor. Now I add examples of my writing style. So I'm putting examples of investor emails I've written. So now it's trained on my writing. So let's get it to write a new email. So now I'm putting in the investor's name and just a little background about them. I click generate. And just like that, I have emails that sound exactly like me. I also built a separate model that is trained on the writing style of my TikTok captions. So for this, I input what the TikTok's about and the tone of voice I want. Anyone can use this to build their own models for any use case you need. You just tell it what input you'll provide and give examples. This can be used for emails, text messages, articles, blogs. If you're a company, this can write copy in exactly your brand voice. If you're interested in this product, fill out the waitlist here and comment down below. I want this so I know that it's useful. It's a way to fine tune GPT to your style of writing.
