Your own custom GPT, step by step

Together we will build a custom GPT assistant for one specific job - from idea to sharing. No programming, just cleverly assembled.

Pick the job

Ideally something you do over and over: writing quotes, answering customers, checking copy, onboarding new people.

Step by step

  1. Give the assistant instructions: who it is, how it writes, what it should and should not do.
  2. Upload source materialfor it to draw on.
  3. Add examples of "this is how I want it" (few-shot).
  4. Test it on real inputs and refine the instructions.
  5. Use it yourself or share it with the team.

When to go further

When you need it wired into your systems, a large volume of data or strict privacy, a custom GPT is not enough - at that point it is a custom-built solution.

What to watch out for

Mind what you upload into the assistant (privacy) and keep checking the output.

A custom assistant is not magic. It is a well-written set of instructions for the AI that you save and reuse over and over.

Want an assistant that goes further than a custom GPT?

I will build one to fit - with your data, inside your systems, and safely. Get in touch.
