GPTs are custom, interactive bots that you can build yourself in minutes using ChatGPT. The end result is a chat interface, just like the normal ChatGPT one, that remembers unique information you used to build it.

In this tutorial, we’ll create a GPT that will write a newsletter post in the style and format you prefer, based on an article you feed it. You can send the newsletter as is, or use it as a base that you can refine and edit until you’re happy. Either way, if you regularly write newsletters, this GPT will save you hours of time.

Steps we’ll follow:

  • Set up your GPT in ChatGPT
  • Configure your GPT to your unique needs and preferences
  • Test and refine the GPT
  • Publish your finished GPT and start writing newsletters in seconds!

Set up your GPT

Log in to ChatGPT and click ‘Explore GPTs’ on the left-hand side of the screen. Click +Create in the top-right corner and you’ll be taken to the build screen.

In the chat area on the left, there are two options: ‘Create’ and ‘Configure.’ Make sure ‘Create’ is selected.

Where the builder asks you “What would you like to make?”, respond with a brief description of your newsletter writer GPT, like this:

I want to build an AI that can transform articles into engaging newsletters in my unique tone and writing style. I need it to be professional yet accessible, ensuring that complex information is presented clearly and understandably.

The GPT builder will continue to suggest a name and a profile image. You can accept them or ask for something different.

Configure your GPT

Now we’ve done the initial setup, the builder will prompt you with questions to help refine the GPT. You can respond back and forth, or, for speed, click the ‘Configure’ tab and enter the following prompt in the Instructions field:

[GPT name] helps you write newsletters in your tone of voice and writing style. You provide articles, and it transforms them into engaging newsletters that reflect your unique voice.

The writing style and tone should be professional yet accessible, ensuring that complex information is presented clearly and understandably.

Key characteristics to emphasize:

- Conciseness: Keep sentences short and to the point, avoiding unnecessary verbosity.
- Clarity: Use straightforward language to make the content easy to understand.
- Professionalism: Maintain a relaxed and fun tone but one that still conveys expertise and reliability. Emulate the tone of voice conveyed in the knowledge files you have access to.
- First Person: Write in the first person: "me" "I" "my" etc.
- Engagement: Include engaging elements such as rhetorical questions or anecdotes where appropriate to keep the reader's interest.
- Actionability: End each newsletter with clear, actionable steps or takeaways that readers can apply immediately, based on the content of that newsletter edition.
- Structure: Use well-organized sections with headings and subheadings to make the content easy to navigate.

Things to avoid:

- Jargon: Minimize the use of industry-specific jargon unless it is essential and explained clearly.
- Redundancy: Avoid repeating information; each point should add unique value.
- Overly Casual Language: While the tone should be accessible, relaxed and fun, it should not be too casual or informal.
- Complex Sentences: Steer clear of overly complex sentences that could confuse the reader.
- Avoid passive voice.
- Avoid overused and cliched phrases. This includes: today's fast-paced world, utilise, game-changer etc.

Newsletters should always be a minimum of 1000 words. They can link to other interesting articles or content where appropriate but keep this to a minimum.

These parameters will instruct the GPT on how to behave whenever its in use.

💡 Tip: The above is a template that we’ve tested and refined until it works reliably and consistently. Feel free to use it as is, or customise it in whatever way works for your needs.

Next, in the Description field, add the following text (or your own version):

Transforms articles into engaging newsletters in your unique tone and writing style. Simply paste the content of an article below and ask the bot to turn it into a newsletter!

This text will show below the profile image whenever you or someone else interacts with the GPT.

Remove any suggested Conversation Starters - they’re not necessary for this GPT. In the Knowledge field, upload files containing examples of your newsletter posts, if you have any. The GPT will use these as a guideline for formatting and style.

Test and refine the GPT

In the ‘Preview’ section on the right of the page, you can test out your GPT. Copy-paste the content of an article with this prompt:

Turn this article into a newsletter:

[insert article contents]
💡 Tip: If the article is especially long or includes images or other assets you’d like the GPT to be aware of, upload a PDF of the article instead of copy-pasting the contents.

If you’re unhappy with any elements of what the GPT produces, go back to the Configure tab and edit the instructions. Keep testing the output in the Preview window using different articles, until you like what’s created.

Publish and share your GPT

When you’ve finished customising your GPT, click ‘Create’ in the top-right corner and you’ll be presented with sharing options. Select your preference and click ‘Share’.

After the sharing link generates, click ‘View GPT’ to see your customised GPT in action. You can share this link with your team or use it yourself to interact with the GPT anytime.

Optimise and refine your GPT

Some tips to ensure your GPT stays up-to-date and effective at its job:

  • Update the knowledge documents with the most current newsletter posts, so the GPT can identify any subtle changes in style or format
  • Provide feedback on the GPT's outputs to help it learn and improve over time
  • Experiment with different prompts and parameters to fine-tune your GPT's performance
