How to create an AI copywriting assistant with custom GPT 

Every so often, clients ask us for a big batch of copy. Today, we introduce them to AI copy assistants. That is a customised ChatGPT that we train on a brand's content and writing style. By feeding it numerous examples and exhaustive prompts, the GPT can lay decent groundwork in mere minutes. Think of it as a junior copywriter on steroids who knows your brand inside out.

All AI experiments we’ve seen so far show that the human factor remains essential. Just as Rubens used to take the work of his assistants up a few levels, our experienced copywriters rewrite the artificial basis. The client still receives a high-quality result.

On openai.com, you can build your own GPT or assistant. Unlike the free version of ChatGPT, you build your own assistant that remembers who he is and how to behave with each task.

First of all, you have to give the GPT an identity. A personality and its corresponding traits. In an in-depth conversation with our client, we gather all the essential information and add it to what we already know.

We define the brand values and mission, their target audience, and the team our brand-new virtual copywriter just joined. The more details we have, the more accurately the assistant will follow our instructions.

And of course, there is the tone of voice. Large language models often mimic writing styles quite well, but then again, sometimes they overdo it. The trick is to feed our assistant with a whole lot of sample copy and content-based input. Rubens's pupils had also seen hundreds of works before they started getting it right. (An assumption to support our story, absolutely)

Your assistant is now trained and ready for a career in artificial copy. Let’s look at an example to illustrate the principle.

Our client moves people and organisations around the globe. To drive their organic traffic, they wanted to create local landing pages for dozens of locations in different countries. These dedicated pages help to attract a target audience that is looking to move to a specific location. On top of that, they help increase the relevance and effectiveness of your paid ads.

Dozens of locations in as many countries; meaning hundreds of pages. As much as our client has enjoyed working with us for many years, this involves a lot of work. And therefore, a lot of working hours. We proposed an AI copy assistant to cater to our customers’ needs.

Once we created the assistant, we wrote one very detailed prompt. A blueprint serving as the basis for all location pages. The only difference: the destination and some location-specific elements.

For every new page, we only had to replace the location. And add the right keywords, of course, since that’s still important if you want to use SEO to boost your organic traffic.

With this slightly altered prompt our creative assistant produced a new page in mere minutes. The adjustable ‘temperature’ allows you to decide how creatively or strictly the system should follow your prompt. All of this gives you everything you need to achieve an original, solid result. A text that is not too similar to the previous one (Google sometimes excludes pages from its search results because they look too much like another page on the same or another website) and which provides your copywriters with a solid starting point.
