If you have heard the term Custom GPT and thought it sounded technical or confusing, you are not alone. In reality, the idea is very simple.
A Custom GPT is a focused version of ChatGPT that has been set up to do one specific job well.
Instead of a general AI that answers anything, a Custom GPT is given clear instructions, boundaries, and reference material so it supports a defined task or role.
Think of it as briefing an assistant properly before they start work.
A plain English example
Normal ChatGPT is like asking questions to someone who knows a bit about everything.
A Custom GPT is like saying: “This assistant only helps with our policies. ”or“ This assistant writes emails in our brand tone.”
It does not guess. It does not decide strategy. It follows the instructions it has been given.
What a Custom GPT can help with
Businesses often use Custom GPTs to:
• answer common internal questions
• draft standard emails or documents
• support training and onboarding
• reinforce policies and procedures
This saves time and improves consistency, especially for teams answering the same questions again and again.
What a Custom GPT does not do
A Custom GPT
• does not think independently
• does not replace professional judgement
• does not automatically know your data unless you give it access
This is why training and clear rules matter.
Why this matters for GDPR and trust
Custom GPTs can be set up to avoid personal data and stick to approved information only. When used correctly, they can support compliance rather than create risk.
At Camari Training, we focus on helping professionals understand how to use AI tools safely, responsibly, and with confidence. The value is not the technology alone. It is knowing how and when to use it.
Key takeaway
A Custom GPT is simply a well-briefed AI assistant for a specific job. It helps reduce repetition, save time, and improve consistency. It works best when people understand its limits and use it responsibly.
If AI feels overwhelming, this is a sensible and practical place to start.
