What are GPT's

June 6, 2026

What a GPT is

AI often feels repetitive. You keep restating tone, structure and rules.

GPTs fix that.

A GPT is a version of ChatGPT that already knows how you want things done. You set it once, then reuse it.

At the same time, AI agents are becoming more common.

  • GPTs improve answers
  • Agents try to handle the task


Most people ask, correct and repeat.

GPTs move you to a setup model. Define the tone and structure once. Each response starts closer to what you want.

A GPT is a customised setup. You define behaviour, role, examples and what to avoid.

You are not changing the model. You are shaping the response.

If you prefer Google tools, you can do something similar with Google Gems in Gemini.



Where GPTs help

Use GPTs for repeatable work:

  • Turn notes into summaries
  • Explain documents in plain English
  • Create email or post templates
  • Structure research

If you repeat the same instruction often, create a GPT.

Quick example

Just using Chat:

“Turn these notes into a short blog post, keep it simple, use headings.”

You then fix tone and structure each time.

After with a GPT:

Open your GPT and paste notes. It already knows your style. You have created the GT to check for grammer, spelling and even given it examples of what good looks like.

You review instead of rewrite. No need to keep repeating yourself with repeatative tasks


Limits

A GPT depends on its setup.

  • Vague instructions give weak results
  • Poor examples give poor output

It still needs checking.

Good examples of useful GPT's



  • Writing assistant for blog drafts
  • Research summariser for long articles
  • Meeting notes organiser
  • Plain English rewriter
  • Content planner for outlines


How to create your first GPT


  • Pick one repeat task
  • Create a GPT in ChatGPT online
  • Add clear instructions
  • Include one or two examples
  • Test and refine

Keep it focused. Improve it over time.

The Nova9 view

We use GPTs a lot! Mainly for research and repeatable tasks such as summarising sources, structuring notes and shaping drafts. We also use ChatGPT to help write the instructions for the GPT. That speeds up setup and improves results early on.


The outcome is simple. less repetition, fewer corrections, more time reviewing.

Agents have their place, but for everyday work, GPTs do most of the heavy lifting without adding risk.
